presentation breech during pregnancy

Fetal Presentation, Position, and Lie (Including Breech Presentation)

• Key Points |

Abnormal fetal lie or presentation may occur due to fetal size, fetal anomalies, uterine structural abnormalities, multiple gestation, or other factors. Diagnosis is by examination or ultrasonography. Management is with physical maneuvers to reposition the fetus, operative vaginal delivery , or cesarean delivery .

Terms that describe the fetus in relation to the uterus, cervix, and maternal pelvis are

Fetal presentation: Fetal part that overlies the maternal pelvic inlet; vertex (cephalic), face, brow, breech, shoulder, funic (umbilical cord), or compound (more than one part, eg, shoulder and hand)

Fetal position: Relation of the presenting part to an anatomic axis; for transverse presentation, occiput anterior, occiput posterior, occiput transverse

Fetal lie: Relation of the fetus to the long axis of the uterus; longitudinal, oblique, or transverse

Normal fetal lie is longitudinal, normal presentation is vertex, and occiput anterior is the most common position.

Abnormal fetal lie, presentation, or position may occur with

Fetopelvic disproportion (fetus too large for the pelvic inlet)

Fetal congenital anomalies

Uterine structural abnormalities (eg, fibroids, synechiae)

Multiple gestation

Several common types of abnormal lie or presentation are discussed here.

Transverse lie

Fetal position is transverse, with the fetal long axis oblique or perpendicular rather than parallel to the maternal long axis. Transverse lie is often accompanied by shoulder presentation, which requires cesarean delivery.

Breech presentation

There are several types of breech presentation.

Frank breech: The fetal hips are flexed, and the knees extended (pike position).

Complete breech: The fetus seems to be sitting with hips and knees flexed.

Single or double footling presentation: One or both legs are completely extended and present before the buttocks.

Types of breech presentations

Breech presentation makes delivery difficult ,primarily because the presenting part is a poor dilating wedge. Having a poor dilating wedge can lead to incomplete cervical dilation, because the presenting part is narrower than the head that follows. The head, which is the part with the largest diameter, can then be trapped during delivery.

Additionally, the trapped fetal head can compress the umbilical cord if the fetal umbilicus is visible at the introitus, particularly in primiparas whose pelvic tissues have not been dilated by previous deliveries. Umbilical cord compression may cause fetal hypoxemia.

Predisposing factors for breech presentation include

Preterm labor

Uterine abnormalities

Fetal anomalies

If delivery is vaginal, breech presentation may increase risk of

Umbilical cord prolapse

Birth trauma

Perinatal death

Face or brow presentation

In face presentation, the head is hyperextended, and position is designated by the position of the chin (mentum). When the chin is posterior, the head is less likely to rotate and less likely to deliver vaginally, necessitating cesarean delivery.

Brow presentation usually converts spontaneously to vertex or face presentation.

Occiput posterior position

The most common abnormal position is occiput posterior.

The fetal neck is usually somewhat deflexed; thus, a larger diameter of the head must pass through the pelvis.

Progress may arrest in the second phase of labor. Operative vaginal delivery or cesarean delivery is often required.

Position and Presentation of the Fetus

If a fetus is in the occiput posterior position, operative vaginal delivery or cesarean delivery is often required.

In breech presentation, the presenting part is a poor dilating wedge, which can cause the head to be trapped during delivery, often compressing the umbilical cord.

For breech presentation, usually do cesarean delivery at 39 weeks or during labor, but external cephalic version is sometimes successful before labor, usually at 37 or 38 weeks.

Fetal Presentation, Position, and Lie (Including Breech Presentation)

• Variations in Fetal Position and Presentation |

During pregnancy, the fetus can be positioned in many different ways inside the mother's uterus. The fetus may be head up or down or facing the mother's back or front. At first, the fetus can move around easily or shift position as the mother moves. Toward the end of the pregnancy the fetus is larger, has less room to move, and stays in one position. How the fetus is positioned has an important effect on delivery and, for certain positions, a cesarean delivery is necessary. There are medical terms that describe precisely how the fetus is positioned, and identifying the fetal position helps doctors to anticipate potential difficulties during labor and delivery.

Presentation refers to the part of the fetus’s body that leads the way out through the birth canal (called the presenting part). Usually, the head leads the way, but sometimes the buttocks (breech presentation), shoulder, or face leads the way.

Position refers to whether the fetus is facing backward (occiput anterior) or forward (occiput posterior). The occiput is a bone at the back of the baby's head. Therefore, facing backward is called occiput anterior (facing the mother’s back and facing down when the mother lies on her back). Facing forward is called occiput posterior (facing toward the mother's pubic bone and facing up when the mother lies on her back).

Lie refers to the angle of the fetus in relation to the mother and the uterus. Up-and-down (with the baby's spine parallel to mother's spine, called longitudinal) is normal, but sometimes the lie is sideways (transverse) or at an angle (oblique).

For these aspects of fetal positioning, the combination that is the most common, safest, and easiest for the mother to deliver is the following:

Head first (called vertex or cephalic presentation)

Facing backward (occiput anterior position)

Spine parallel to mother's spine (longitudinal lie)

Neck bent forward with chin tucked

Arms folded across the chest

If the fetus is in a different position, lie, or presentation, labor may be more difficult, and a normal vaginal delivery may not be possible.

Variations in fetal presentation, position, or lie may occur when

The fetus is too large for the mother's pelvis (fetopelvic disproportion).

The uterus is abnormally shaped or contains growths such as fibroids .

The fetus has a birth defect .

There is more than one fetus (multiple gestation).

Position and Presentation of the Fetus

Variations in fetal position and presentation.

Some variations in position and presentation that make delivery difficult occur frequently.

Occiput posterior position

In occiput posterior position (sometimes called sunny-side up), the fetus is head first (vertex presentation) but is facing forward (toward the mother's pubic bone—that is, facing up when the mother lies on her back). This is a very common position that is not abnormal, but it makes delivery more difficult than when the fetus is in the occiput anterior position (facing toward the mother's spine—that is facing down when the mother lies on her back).

When a fetus faces up, the neck is often straightened rather than bent,which requires more room for the head to pass through the birth canal. Delivery assisted by a vacuum device or forceps or cesarean delivery may be necessary.

Breech presentation

In breech presentation, the baby's buttocks or sometimes the feet are positioned to deliver first (before the head).

When delivered vaginally, babies that present buttocks first are more at risk of injury or even death than those that present head first.

The reason for the risks to babies in breech presentation is that the baby's hips and buttocks are not as wide as the head. Therefore, when the hips and buttocks pass through the cervix first, the passageway may not be wide enough for the head to pass through. In addition, when the head follows the buttocks, the neck may be bent slightly backwards. The neck being bent backward increases the width required for delivery as compared to when the head is angled forward with the chin tucked, which is the position that is easiest for delivery. Thus, the baby’s body may be delivered and then the head may get caught and not be able to pass through the birth canal. When the baby’s head is caught, this puts pressure on the umbilical cord in the birth canal, so that very little oxygen can reach the baby. Brain damage due to lack of oxygen is more common among breech babies than among those presenting head first.

In a first delivery, these problems may occur more frequently because a woman’s tissues have not been stretched by previous deliveries. Because of risk of injury or even death to the baby, cesarean delivery is preferred when the fetus is in breech presentation, unless the doctor is very experienced with and skilled at delivering breech babies or there is not an adequate facility or equipment to safely perform a cesarean delivery.

Breech presentation is more likely to occur in the following circumstances:

Labor starts too soon (preterm labor).

The uterus is abnormally shaped or contains abnormal growths such as fibroids .

Other presentations

In face presentation, the baby's neck arches back so that the face presents first rather than the top of the head.

In brow presentation, the neck is moderately arched so that the brow presents first.

Usually, fetuses do not stay in a face or brow presentation. These presentations often change to a vertex (top of the head) presentation before or during labor. If they do not, a cesarean delivery is usually recommended.

In transverse lie, the fetus lies horizontally across the birth canal and presents shoulder first. A cesarean delivery is done, unless the fetus is the second in a set of twins. In such a case, the fetus may be turned to be delivered through the vagina.

Appointments at Mayo Clinic

• Pregnancy week by week
• Fetal presentation before birth

The way a baby is positioned in the uterus just before birth can have a big effect on labor and delivery. This positioning is called fetal presentation.

Babies twist, stretch and tumble quite a bit during pregnancy. Before labor starts, however, they usually come to rest in a way that allows them to be delivered through the birth canal headfirst. This position is called cephalic presentation. But there are other ways a baby may settle just before labor begins.

Following are some of the possible ways a baby may be positioned at the end of pregnancy.

Head down, face down

When a baby is head down, face down, the medical term for it is the cephalic occiput anterior position. This the most common position for a baby to be born in. With the face down and turned slightly to the side, the smallest part of the baby's head leads the way through the birth canal. It is the easiest way for a baby to be born.

Head down, face up

When a baby is head down, face up, the medical term for it is the cephalic occiput posterior position. In this position, it might be harder for a baby's head to go under the pubic bone during delivery. That can make labor take longer.

Most babies who begin labor in this position eventually turn to be face down. If that doesn't happen, and the second stage of labor is taking a long time, a member of the health care team may reach through the vagina to help the baby turn. This is called manual rotation.

In some cases, a baby can be born in the head-down, face-up position. Use of forceps or a vacuum device to help with delivery is more common when a baby is in this position than in the head-down, face-down position. In some cases, a C-section delivery may be needed.

Frank breech

When a baby's feet or buttocks are in place to come out first during birth, it's called a breech presentation. This happens in about 3% to 4% of babies close to the time of birth. The baby shown below is in a frank breech presentation. That's when the knees aren't bent, and the feet are close to the baby's head. This is the most common type of breech presentation.

If you are more than 36 weeks into your pregnancy and your baby is in a frank breech presentation, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. It involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a breech position, talk with a member of your health care team about the choices you have for delivery. Most babies in a frank breech position are born by planned C-section.

Complete and incomplete breech

A complete breech presentation, as shown below, is when the baby has both knees bent and both legs pulled close to the body. In an incomplete breech, one or both of the legs are not pulled close to the body, and one or both of the feet or knees are below the baby's buttocks. If a baby is in either of these positions, you might feel kicking in the lower part of your belly.

If you are more than 36 weeks into your pregnancy and your baby is in a complete or incomplete breech presentation, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. It involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a breech position, talk with a member of your health care team about the choices you have for delivery. Many babies in a complete or incomplete breech position are born by planned C-section.

When a baby is sideways — lying horizontal across the uterus, rather than vertical — it's called a transverse lie. In this position, the baby's back might be:

• Down, with the back facing the birth canal.
• Sideways, with one shoulder pointing toward the birth canal.
• Up, with the hands and feet facing the birth canal.

Although many babies are sideways early in pregnancy, few stay this way when labor begins.

If your baby is in a transverse lie during week 37 of your pregnancy, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. External cephalic version involves one or two members of your health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a transverse lie, talk with a member of your health care team about the choices you have for delivery. Many babies who are in a transverse lie are born by C-section.

If you're pregnant with twins and only the twin that's lower in the uterus is head down, as shown below, your health care provider may first deliver that baby vaginally.

Then, in some cases, your health care team may suggest delivering the second twin in the breech position. Or they may try to move the second twin into a head-down position. This is done using a procedure called external cephalic version. External cephalic version involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

Your health care team may suggest delivery by C-section for the second twin if:

• An attempt to deliver the baby in the breech position is not successful.
• You do not want to try to have the baby delivered vaginally in the breech position.
• An attempt to move the baby into a head-down position is not successful.
• You do not want to try to move the baby to a head-down position.

In some cases, your health care team may advise that you have both twins delivered by C-section. That might happen if the lower twin is not head down, the second twin has low or high birth weight as compared to the first twin, or if preterm labor starts.

What Causes Breech Presentation?

What Is Breech Presentation?

Types of breech presentation, what causes a breech baby, can you turn a breech baby, how are breech babies delivered.

FatCamera/Getty Images

Toward the end of pregnancy, your baby will start to get into position for delivery, with their head pointed down toward the vagina. This is otherwise known as vertex presentation. However, some babies turn inside the womb so that their feet or buttocks are poised to be delivered first, which is commonly referred to as breech presentation, or a breech baby.

As you near the end of your pregnancy journey, an OB-GYN or health care provider will check your baby's positioning. You might find yourself wondering: What causes breech presentation? Are there risks involved? And how are breech babies delivered? We turned to experts and research to answer some of the most common questions surrounding breech presentation, along with what causes this positioning in the first place.

During your pregnancy, your baby constantly moves around the uterus. Indeed, most babies do somersaults up until the 36th week of pregnancy , when they pick their final position in the womb, says Laura Riley , MD, an OB-GYN in New York City. Approximately 3-4% of babies end up “upside-down” in breech presentation, with their feet or buttocks near the cervix.

Breech presentation is typically diagnosed during a visit to an OB-GYN, midwife, or health care provider. Your physician can feel the position of your baby's head through your abdominal wall—or they can conduct a vaginal exam if your cervix is open. A suspected breech presentation should ultimately be confirmed via an ultrasound, after which you and your provider would have a discussion about delivery options, potential issues, and risks.

There are three types of breech babies: frank, footling, and complete. Learn about the differences between these breech presentations.

Frank Breech

With frank breech presentation, your baby’s bottom faces the cervix and their legs are straight up. This is the most common type of breech presentation.

Footling Breech

Like its name suggests, a footling breech is when one (single footling) or both (double footling) of the baby's feet are in the birth canal, where they’re positioned to be delivered first .

Complete Breech

In a complete breech presentation, baby’s bottom faces the cervix. Their legs are bent at the knees, and their feet are near their bottom. A complete breech is the least common type of breech presentation.

Other Types of Mal Presentations

The baby can also be in a transverse position, meaning that they're sideways in the uterus. Another type is called oblique presentation, which means they're pointing toward one of the pregnant person’s hips.

Typically, your baby's positioning is determined by the fetus itself and the shape of your uterus. Because you can't can’t control either of these factors, breech presentation typically isn’t considered preventable. And while the cause often isn't known, there are certain risk factors that may increase your risk of a breech baby, including the following:

• The fetus may have abnormalities involving the muscular or central nervous system
• The uterus may have abnormal growths or fibroids
• There might be insufficient amniotic fluid in the uterus (too much or too little)
• This isn’t your first pregnancy
• You have a history of premature delivery
• You have placenta previa (the placenta partially or fully covers the cervix)
• You’re pregnant with multiples
• You’ve had a previous breech baby

In some cases, your health care provider may attempt to help turn a baby in breech presentation through a procedure known as external cephalic version (ECV). This is when a health care professional applies gentle pressure on your lower abdomen to try and coax your baby into a head-down position. During the entire procedure, the fetus's health will be monitored, and an ECV is often performed near a delivery room, in the event of any potential issues or complications.

However, it's important to note that ECVs aren't for everyone. If you're carrying multiples, there's health concerns about you or the baby, or you've experienced certain complications with your placenta or based on placental location, a health care provider will not attempt an ECV.

The majority of breech babies are born through C-sections . These are usually scheduled between 38 and 39 weeks of pregnancy, before labor can begin naturally. However, with a health care provider experienced in delivering breech babies vaginally, a natural delivery might be a safe option for some people. In fact, a 2017 study showed similar complication and success rates with vaginal and C-section deliveries of breech babies.

That said, there are certain known risks and complications that can arise with an attempt to deliver a breech baby vaginally, many of which relate to problems with the umbilical cord. If you and your medical team decide on a vaginal delivery, your baby will be monitored closely for any potential signs of distress.

Ultimately, it's important to know that most breech babies are born healthy. Your provider will consider your specific medical condition and the position of your baby to determine which type of delivery will be the safest option for a healthy and successful birth.

INTRODUCTION

This topic will provide an overview of major issues related to breech presentation, including choosing the best route for delivery. Techniques for breech delivery, with a focus on the technique for vaginal breech delivery, are discussed separately. (See "Delivery of the singleton fetus in breech presentation" .)

TYPES OF BREECH PRESENTATION

● Frank breech – Both hips are flexed and both knees are extended so that the feet are adjacent to the head ( figure 1 ); accounts for 50 to 70 percent of breech fetuses at term.

● Complete breech – Both hips and both knees are flexed ( figure 2 ); accounts for 5 to 10 percent of breech fetuses at term.

Risk Factors

Complications.

Breech concerns the position of the fetus before labor . Typically, the fetus comes out headfirst, but in a breech delivery, the buttocks or feet come out first. This type of delivery is risky for both the pregnant person and the fetus.

This article discusses the different types of breech presentations, risk factors that might make a breech presentation more likely, treatment options, and complications associated with a breech delivery.

Verywell / Jessica Olah

Types of Breech Presentation

During the last few weeks of pregnancy, a fetus usually rotates so that the head is positioned downward to come out of the vagina first. This is called the vertex position.

In a breech presentation, the fetus does not turn to lie in the correct position. Instead, the fetus’s buttocks or feet are positioned to come out of the vagina first.

At 28 weeks of gestation, approximately 20% of fetuses are in a breech position. However, the majority of these rotate to the proper vertex position. At full term, around 3%–4% of births are breech.

The different types of breech presentations include:

• Complete : The fetus’s knees are bent, and the buttocks are presenting first.
• Frank : The fetus’s legs are stretched upward toward the head, and the buttocks are presenting first.
• Footling : The fetus’s foot is showing first.

Signs of Breech

There are no specific symptoms associated with a breech presentation.

Diagnosing breech before the last few weeks of pregnancy is not helpful, since the fetus is likely to turn to the proper vertex position before 35 weeks gestation.

A healthcare provider may be able to tell which direction the fetus is facing by touching a pregnant person’s abdomen. However, an ultrasound examination is the best way to determine how the fetus is lying in the uterus.

Most breech presentations are not related to any specific risk factor. However, certain circumstances can increase the risk for breech presentation.

These can include:

• Previous pregnancies
• Multiple fetuses in the uterus
• An abnormally shaped uterus
• Uterine fibroids , which are noncancerous growths of the uterus that usually appear during the childbearing years
• Placenta previa, a condition in which the placenta covers the opening to the uterus
• Preterm labor or prematurity of the fetus
• Too much or too little amniotic fluid (the liquid that surrounds the fetus during pregnancy)
• Fetal congenital abnormalities

Most fetuses that are breech are born by cesarean delivery (cesarean section or C-section), a surgical procedure in which the baby is born through an incision in the pregnant person’s abdomen.

In rare instances, a healthcare provider may plan a vaginal birth of a breech fetus. However, there are more risks associated with this type of delivery than there are with cesarean delivery. 

Before cesarean delivery, a healthcare provider might utilize the external cephalic version (ECV) procedure to turn the fetus so that the head is down and in the vertex position. This procedure involves pushing on the pregnant person’s belly to turn the fetus while viewing the maneuvers on an ultrasound. This can be an uncomfortable procedure, and it is usually done around 37 weeks gestation.

ECV reduces the risks associated with having a cesarean delivery. It is successful approximately 40%–60% of the time. The procedure cannot be done once a pregnant person is in active labor.

Complications related to ECV are low and include the placenta tearing away from the uterine lining, changes in the fetus’s heart rate, and preterm labor.

ECV is usually not recommended if the:

• Pregnant person is carrying more than one fetus
• Placenta is in the wrong place
• Healthcare provider has concerns about the health of the fetus
• Pregnant person has specific abnormalities of the reproductive system

Recommendations for Previous C-Sections

The American College of Obstetricians and Gynecologists (ACOG) says that ECV can be considered if a person has had a previous cesarean delivery.

During a breech delivery, the umbilical cord might come out first and be pinched by the exiting fetus. This is called cord prolapse and puts the fetus at risk for decreased oxygen and blood flow. There’s also a risk that the fetus’s head or shoulders will get stuck inside the mother’s pelvis, leading to suffocation.

Complications associated with cesarean delivery include infection, bleeding, injury to other internal organs, and problems with future pregnancies.

A healthcare provider needs to weigh the risks and benefits of ECV, delivering a breech fetus vaginally, and cesarean delivery.

In a breech delivery, the fetus comes out buttocks or feet first rather than headfirst (vertex), the preferred and usual method. This type of delivery can be more dangerous than a vertex delivery and lead to complications. If your baby is in breech, your healthcare provider will likely recommend a C-section.

A Word From Verywell

Knowing that your baby is in the wrong position and that you may be facing a breech delivery can be extremely stressful. However, most fetuses turn to have their head down before a person goes into labor. It is not a cause for concern if your fetus is breech before 36 weeks. It is common for the fetus to move around in many different positions before that time.

At the end of your pregnancy, if your fetus is in a breech position, your healthcare provider can perform maneuvers to turn the fetus around. If these maneuvers are unsuccessful or not appropriate for your situation, cesarean delivery is most often recommended. Discussing all of these options in advance can help you feel prepared should you be faced with a breech delivery.

What Does It Mean to Have a Breech Baby?

You’re almost full term and the finish line is approaching, when suddenly your OB or midwife informs you that baby is breech—plot twist! If baby is in a breech position, it means their feet or bottom is pointed toward your cervix rather than their head. You’ve just encountered an early example of a universal truth in parenting: Few things ever go as perfectly as you planned.

A breech birth often means a c-section delivery is in store for you, and that can feel disappointing and worrisome, especially if you’ve been hoping to deliver vaginally. Deep breath— you may still have options; your doctor will talk you through everything well before the big day comes. In the meantime, it’s helpful to get a better grasp on all things breech baby. Want to know how to tell if baby is breech, what the position means for your pregnancy, how it affects delivery and ways your doctor (and you!) can try to turn baby? Read on for the full lowdown.

What Is a Breech Baby?

In the last few weeks of pregnancy, most babies move in the womb so that their heads are facing down, positioned to come out of the vagina first during delivery. But if baby is breech, their head is not approaching the birth canal; rather, it’s their feet or bottom that’s poised to come out first.

Types of breech positions

There are three different types of breech positions, according to the American Pregnancy Association :

• Complete. Baby’s buttocks are pointing down and legs are crossed beneath it
• Frank. Baby’s bottom is positioned down and legs are pointed up toward the head
• Footling. Baby has one leg pointed toward the cervix, poised to deliver before the rest of their body. “There’s also a double footling breech, where the baby’s feet and legs are facing down toward the cervix,” says Elizabeth Deckers , MD, director of the maternal quality and safety program at Hartford HealthCare.

Baby could also be in a transverse lie position (occasionally referred to as a transverse breech position). This means that they’re horizontal across the uterus instead of vertical.

What percentage of babies are breech?

According to the American Pregnancy Association, approximately 1 out of every 25 full-term births involves a baby in a breech position. That means roughly 4 percent of babies have their bottom and/or feet pointed down toward the birth canal.

Why a Breech Position Can Be a Concern

Your doctor won’t be too concerned if baby is in a breech position throughout most of your pregnancy. In fact, it’s likely that at some point in your second or early third trimester, baby will be breech. At this early stage, though, baby is smaller and has more room to move around and turn, notes Deckers.

As baby grows and your due date nears, a breech position becomes slightly more concerning. For starters, there’s some evidence linking a breech presentation—and its tendency to reduce the amount of space in the womb—with hip dysplasia , a condition where the ball and socket joint of baby’s hip doesn’t properly form.

Your doctor or midwife may raise a red flag if baby is in breech position at 36 weeks or later. At this point, they’ll probably start talking about the potential need for a c-section. “Vaginal breech delivery is no longer commonly done in the US because about 20 years ago there was a large, well-designed trial that showed there was more risk to the fetus of going through a vaginal breech delivery versus being born by a c-section,” says Deckers. The trial showed that breech babies born vaginally were more likely to have fetal fractures and a harder time getting out of the birth canal, says Amber Samuel , MD, medical director of Obstetrix Maternal-Fetal Medicine Specialists of Houston. Deckers reiterates this, noting that most babies in the US identified as breech will be born via c-section, as doctors “believe it’s safer in the short run for baby.”

What Causes a Breech Pregnancy?

Don’t beat yourself up or worry that you did something wrong in pregnancy to put baby into a breech position. The truth is there’s usually no rhyme or reason to explain baby’s breech presentation, says Samuel. That said, if you have a uterine anomaly, where your uterus is wider at the top or generally more narrow, it may play a role, she says. “If the shape is abnormal, some babies get stuck,” she says. Having too much amniotic fluid around baby might also be a potential factor.

The American College of Obstetricians and Gynecologists (ACOG) lists other factors that might contribute to baby being breech: you’ve been pregnant before, you’re expecting twins or multiples, you have placenta previa (where your placenta is covering part of your uterine opening) or baby is preterm . Suffice it to say, though, that these potential breech baby causes are out of your control.

How to Tell If Baby Is Breech

You might be able to detect that baby is breech if you feel them kick low near your cervix or feel their head under your ribs, says Deckers. Samuel notes that some moms who’ve had babies before are really good at determining how and where they’re positioned.

Doctors gauge baby’s position by placing their hands on different parts of your belly to feel where fetal parts are, a technique known as Leopold’s maneuvers, explains Samuel. They may also perform a cervical exam to see if they can feel any presenting parts. Sometime around 36 or 37 weeks, they’ll confirm baby’s position with an ultrasound.

What to Expect from a Breech Pregnancy

You may not know if or when baby is in a breech position. Earlier on in your pregnancy, when they’re smaller and have more room in the womb, they may flip all around; roughly 20 percent of babies are breech at 28 weeks, says Samuel. If you discover that your little acrobat is breech at this stage, don’t panic; there’s still more than enough time for them to flip into the preferred position (and then possibly do a few more rotations).

Are breech babies more painful to carry?

The good news: Breech presentation doesn’t typically cause discomfort or pain during pregnancy, Samuel says. Pain is more likely related to “prior scar tissue, the size of your baby and your pregnancy history,” she adds.

What to Expect from a Breech Delivery

There is a possibility for a vaginal breech birth under the right circumstances. Deckers notes that you may be a candidate if baby is in a frank or complete breech presentation and your pelvic structure is adequate for vaginal birth—and if your hospital has guidelines in place for a planned vaginal breech delivery. Unfortunately, the risk of the umbilical cord falling through the cervix is too high with a double footling breech; there’s also a higher risk that baby will get stuck during delivery, which can cause birth asphyxia. Of course, you’ll also want to ensure that your doctor has a lot of experience with vaginal breech delivery and that your hospital will allow it.

If baby is in a breech position beyond 36 weeks and your doctor feels that a vaginal birth is too risky, they’ll likely recommend that you allow them to try turning baby— more on that soon . If that’s not successful, you’ll be scheduled for a c-section, says Samuel.

Having twins where one is breech changes the game a little too. If the baby that’s poised to come out first is breech, you’ll have to deliver via c-section, says Deckers. But if the first baby is head down and second is not, you and your OB have three options: deliver both via c-section; deliver the first baby vaginally and then attempt to turn the second one to deliver vaginally (if it’s unsuccessful, you’ll proceed with a c-section) or deliver the first vaginally and then do a breech extraction of the second baby (your OB will reach inside to grasp baby’s feet and pull them down.)

“The ability to do a safe breech extraction depends on the gestational age of the babies, how well the mother and babies are tolerating labor, the size of the babies and a provider with experience in performing this procedure,” says Deckers.

How to Turn a Breech Baby

Many parents want to have a vaginal birth; what’s more, they know that a c-section is a major surgery with inherent risks. To that end, before scheduling a c-section, most doctors will suggest trying an external cephalic version (ECV), which is an attempt to turn baby from the outside.

First you’ll be given medication to relax your uterus; don’t worry, your doctor will continually monitor baby. “One hand elevates the fetal breech out of the pelvis and you push up and away from the pelvis,” says Samuel. “The other hand is on the back of baby’s head to induce them to turn over—it looks like an aggressive belly massage.”

Your doctor will push baby forward before attempting a backward roll. “You can tell pretty early into it whether it’s going to work or not—some babies are ready to flip, some aren’t,” says Samuel. “We try not to struggle too much with it.”

External cephalic versions are successful roughly 58 percent of the time, says Deckers, although there’s always the chance that baby will flip back to breech on their own. If the turning is successful and you’re at 39 weeks, you can choose to be induced. If it didn’t work, you’ll be scheduled for a c-section. ECVs should only be performed in hospitals equipped to perform emergency c-sections ; risks of the procedure, which are rare, include bleeding from the placenta, rupture of membranes and going into labor, says Samuel.

It’s also worth noting that not every mom is a candidate for an EVC. If you’re having multiples or there’s a problem with placental position, an EVC is too risky, according to the ACOG.

Safe ways to try to turn a breech baby at home

If you prefer to try to make things happen on your own, there are a few things you can do to help turn a breech baby from the comfort of your home. Deckers notes, though, that research on DIY techniques hasn’t provided strong enough evidence to prove that they really work.

A little bit of gentle prenatal yoga may help. One pose to practice? Deckers says some moms try “a head down/knee-to-chest position.” You can also assume a few different sleeping positions to turn a breech baby: “Mothers can try positional things like elevating your pelvis,” she says. Finally, Deckers mentions two Eastern medicine techniques that many moms actively seek out: acupuncture and moxibustion, a therapy that involves waving burning dried plant bundles over specific parts of the body to encourage baby to turn on their own. These methods have been long used, but she points out that the efficacy of these methods haven’t been proven in trials, so “the data isn’t compelling enough to say this is something you should do.”

What to Expect for a Breech Baby After Birth

If baby is presenting breech and you and your doctor decide to move forward with a vaginal delivery, there are some potential complications to be aware of that could ultimately affect baby’s health and well being.

It’s possible for baby’s head or shoulders to get wedged against your pelvic bones; a prolapsed umbilical cord could also decrease blood flow and cut off baby’s oxygen supply, explains the ACOG. That said, even a planned c-section comes with its own set of risks.

Welcoming a healthy baby into the world is the ultimate goal, regardless of how they’re delivered. Interestingly, babies who’ve been in breech presentation and are delivered via c-section tend to have nicely shaped heads because there’s none of the swelling and other head-shifting changes that occur in babies delivered through the birth canal, notes Deckers.

Do breech babies have problems later in life?

Sometimes babies who were breech have issues with their hips, as having one or both legs extended in a partially straight position rather than crossed can prevent a baby’s hip socket from developing properly. If your child was breech, Deckers recommends following up with your pediatrician.

Having a breech baby was probably not in your original birth plan. Your stubborn little one may turn before their grand debut, or they may—quite literally—put their foot down and refuse to budge. Either way, talk to your doctor about any concerns. And remember, the good news is that baby is coming soon, either way!

What to know if your baby is breech

Find out what breech position means, how to turn a breech baby, and what having a breech baby means for your labor and delivery.

What does it mean when a baby is breech?

Breech is a term used to describe your baby's position in the womb. Breech position means your baby is bottom-down instead of head-down.

Babies are often active in early pregnancy, moving into different positions. But by around 8 months, there's not much room in the uterus. Most babies maximize their cramped quarters by settling in head down, in what's known as a cephalic or vertex presentation. But if you have a breech baby, it means they're poised to come out buttocks and/or feet first. At 28 weeks or less, about a quarter of babies are breech, and at 32 weeks, 7 percent are breech. By the end of pregnancy, only 3 to 4 percent of babies are in breech position. At term, a baby in breech position is unlikely to turn on their own.

There are several types of breech presentations:

• Frank breech (bottom first with feet up near the head)
• Complete breech (bottom first with legs crossed)
• Incomplete or footling breech (one or both feet are poised to come out first)

(In rare cases, a baby will be sideways in the uterus with their shoulder, back, or arm presenting first – this is called a transverse lie.)

See what these breech presentations look like .

If your baby is in breech position, you may feel them kicking in your lower belly. Or you may feel pressure under your ribcage, from their head.

By the beginning of your third trimester , your practitioner may be able to tell what position your baby is in by feeling your abdomen and locating the baby's head, back, and bottom.

If your baby's position isn't clear during an abdominal exam at 36 weeks, your caregiver may do an internal exam to try to feel what part of the baby is in your pelvis. In some cases, they may use ultrasound to confirm the baby's position.

We don't usually know why some babies are breech – in most cases it seems to be chance. While sometimes a baby with certain birth defects may not turn to a head-down position, most babies in breech position are perfectly fine. Here are some things that might increase the risk of a breech presentation:

• You're carrying multiples
• You've been pregnant before
• You've had a breech presentation before
• There's too much amniotic fluid or not enough amniotic fluid
• You have placenta previa (the placenta is covering all of part of the opening of the uterus)
• Your baby is preterm
• Your uterus is shaped abnormally or has growths, such as fibroids
• The umbilical cord is short
• You were a breech delivery, or your sibling or parent was a breech delivery
• Advanced maternal age (especially age 45 and older)
• Your baby is a low weight at delivery
• You're having a girl

There is a procedure for turning a breech baby. It's called an external cephalic version (ECV). An ob/gyn turns your baby by applying pressure to your abdomen and manually manipulating the baby into a head-down position. Some women find it very uncomfortable or even painful.

An EVC has about a 58 percent success rate, and it's more likely to work if this isn't your first baby. It's not for everyone – you can't have the procedure if you're carrying multiples or if you have too little amniotic fluid or placental abruption , for example. Your provider also won't attempt to turn your breech baby if your baby has any health problems.

The procedure is done after 36 weeks and in the hospital, where your baby can be monitored and where you'll be near a delivery room should any complications arise.

It depends, and it's something you'll want to talk with your caregiver about ahead of time. Discuss your preferences, the advantages and risks of each option ( vaginal and cesarean delivery of a breech presentation), and their experience. The biggest risk of a breech delivery is when the body delivers but the head stays entrapped within the cervix.

In the United States, most breech babies are delivered via cesarean. You may wind up having a vaginal breech delivery if your labor is so rapid that you arrive at the hospital just about to deliver. Another scenario is if you have a twin pregnancy where the first baby is in the head-first position and the second baby is not. A baby who delivers head-first will make room for the breech baby.

However, the vast majority of babies who remain breech arrive by c-section. If a c-section is planned, it will usually be scheduled at 39 weeks. To make sure your baby hasn't changed position in the meantime, you'll have an ultrasound at the hospital to confirm their position just before the surgery.

If you go into labor or your water will break s before your planned c-section, be sure to call your provider right away and head for the hospital.

In rare circumstances, if you're at low risk of complications and your caregiver is experienced delivering breech babies vaginally, you may choose to have what is called a "trial of vaginal birth." This means that you can attempt to deliver vaginally but should be prepared to have a cesarean delivery if labor isn't progressing well. You and your baby will be closely monitored during labor.

In addition to ECV, there are some alternative, natural ways to try to turn your baby. There's no proof that any of them work – or that all of them are safe. Consult your practitioner before trying them.

There's no conclusive proof that the mother's position has any effect on the baby's position, but the idea is to employ gravity to help your baby somersault into a head-down position. A few tips:

• Get into one of the following positions twice a day, starting at around 32 weeks.
• Be sure to do these moves on an empty stomach, lest your lunch comes back up.
• Make sure there's someone around to help you get up if you start feeling lightheaded.
• If you find these positions uncomfortable, stop doing them.

Position 1: Lie flat on your back and raise your pelvis so that it's 9 to 12 inches off the floor. Support your hips with a pillow and stay in this position for five to 15 minutes. Position 2: Kneel down, with your forearms on the floor in front of you, so that your bottom sticks up in the air. Stay in this position for five to 15 minutes. Sleeping position

Many women wonder if there are sleeping positions to turn a breech baby. But the positions you use to try to coax your baby head down for a short time shouldn't be used while you're sleeping. (It's not safe to sleep flat on your back in late pregnancy, for example, because the weight of your baby may compress the blood vessels that provide oxygen and nutrients to them.)

The best position for sleeping during pregnancy is on your side. Placing a pillow between your legs in this position may help open your pelvis, giving your baby room to move more easily. Support your back with plenty of pillows, too. Again, there's no proof that this works, but since it's the best sleeping position for you and your baby, you may as well give it a try.

Moxibustion

This ancient Chinese technique burns herbs to stimulate key acupressure points. To help turn a breech baby, an acupuncturist or other practitioner burns mugwort near the acupressure point of your pinky toes. According to Chinese medicine, this should stimulate your baby's activity enough that they may change position on their own. Some studies show that moxibustion in combination with acupuncture and/or positioning methods may be of some benefit. Others show moxibustion to provide no help in coaxing a baby into cephalic position. If you've discussed it with your caregiver and want to give it a try, contact your state acupuncture or Chinese medicine association and ask for the names of licensed practitioners.

One small study found that women who are regularly hypnotized into a state of deep relaxation at 37 to 40 weeks are more likely to have their baby turn than other women. If you're willing to try this technique, look for a licensed hypnotherapist with experience working with pregnant women.

Chiropractic care

There's a technique – called The Webster Breech Technique – that aims to reduce stress on the pelvis by relaxing the uterus and surrounding ligaments. The idea is that a breech baby can turn more naturally in a relaxed uterus, but research is limited as to the risks and benefits of this technique. If you're interested, talk with your provider about working with a chiropractor who's experienced with the technique.

This is a safe – and again, unproven – method based on the fact that your baby can hear sounds outside the womb. Simply play music close to the lower part of your abdomen (some women use headphones) to encourage your baby to move in the direction of the sound.

Baby Breech

Posted March 22, 2024

Babies change positions in the uterus many times during the first 36 weeks of pregnancy. In the last few weeks, they will move less as there is less room. By three to four weeks prior to the due date, most babies will position themselves so their head is near the birth canal. If a baby does not move into this position and the baby’s feet, buttocks, or both are positioned to come out first, this is called a breech position. This occurs in about three percent of full-term births. Most breech babies are healthy, but they have a higher risk for certain problems.

Breech position is more common when:

• The woman has had more than one pregnancy.
• There is more than one fetus in the uterus.
• The uterus has too much or too little amniotic fluid.
• The uterus is not normal in shape or has abnormal growths like fibroids.
• The placenta partly or fully covers the opening of the cervix.
• The baby is preterm.

Finding the Baby’s Position

Your health care provider can determine the baby’s position by placing their hands at certain points on the abdomen to feel the baby’s head, back, and buttocks. Because babies may change position up until delivery, they may not be able to tell for sure if the baby has settled into a breech position.

Ultrasound may also be used to confirm the baby’s position.

Can a Breech Presentation be Changed?

Your health care provider may try to turn the baby into a head-down position using a technique called an external cephalic version. This may be attempted if you are at least 36 weeks along.

Your health care provider will use an ultrasound exam to determine the placement of the baby and view the baby during the turning. To perform a version, the health care provider will place their hands at certain points on your abdomen and then push the baby into a head-down position. At all times, your baby’s heartbeat will be closely monitored. If any problems arise during the version, it will be stopped right away. More than half of the attempts are successful.

Risks of a version include:

• Rupture of membranes.
• Problems with the baby’s heart rate.
• Labor may begin.
• Placental abruption.

Talk with your health care provider to determine if a version is an option for you.

Vaginal delivery of a breech baby carries more risk. Because the head is the largest and firmest part of the baby, and during a breech birth it comes out last, it may be harder to ease through the birth canal. There is also an increased risk of a prolapsed cord, where the umbilical cord slips through the cervix and enters the birth canal before the baby. This can stop the flow of blood through the cord.

Cesarean delivery may pose less risk but is still difficult. Cesarean delivery is major surgery that carries its own risks, including:

• Heavy bleeding.
• Problems from the pain medication.

Cesarean deliveries are the best option for most women if the baby is breech.

Most breech babies are born healthy. Talk with your health care provider about your options for delivery if your baby is in the breech position as your due date approaches.

To determine if the common risks for breech presentation at term labor are also eligible in preterm labor.

A Finnish cross-sectional study included 737,788 singleton births (24–42 gestational weeks) during 2004–2014. A multivariable logistic regression analysis was used to calculate the risks of breech presentation.

The incidence of breech presentation at delivery decreased from 23.5% in pregnancy weeks 24–27 to 2.5% in term pregnancies. In gestational weeks 24–27, preterm premature rupture of membranes was associated with breech presentation. In 28–31 gestational weeks, breech presentation was associated with maternal pre-eclampsia/hypertension, preterm premature rupture of membranes, and fetal birth weight below the tenth percentile. In gestational weeks 32–36, the risks were advanced maternal age, nulliparity, previous cesarean section, preterm premature rupture of membranes, oligohydramnios, birth weight below the tenth percentile, female sex, and congenital anomaly. In term pregnancies, breech presentation was associated with advanced maternal age, nulliparity, maternal hypothyroidism, pre-gestational diabetes, placenta praevia, premature rupture of membranes, oligohydramnios, congenital anomaly, female sex, and birth weight below the tenth percentile.

Breech presentation in preterm labor is associated with obstetric risk factors compared to cephalic presentation. These risks decrease linearly with the gestational age. In moderate to late preterm delivery, breech presentation is a high-risk state and some obstetric risk factors are yet visible in early preterm delivery. Breech presentation in extremely preterm deliveries has, with the exception of preterm premature rupture of membranes, similar clinical risk profiles as in cephalic presentation.

Introduction

The prevalence of breech presentation at delivery decreases with increasing gestational age. At 28 pregnancy weeks, every fifth fetus lies in the breech presentation and in term pregnancies, less than 4% of all singleton fetuses are in breech presentation at delivery [ 1 , 2 ]. Most likely this is due to a lack of fetal movements [ 3 ] or an incomplete fetal rotation, since the possibility of a spontaneous rotation declines with increasing gestational age. Consequently, preterm labor itself is often associated with breech presentation at delivery, since the fetus was not yet able to rotate [ 4 – 9 ]. This fact makes preterm labor as one of the strongest risk factors for breech presentation.

Vaginal breech delivery in term pregnancies is not only associated with poorer perinatal outcomes compared to vaginal delivery with a fetus in cephalic presentation [ 6 , 10 , 11 ], but also it is debated whether the cause of breech presentation itself is a risk for adverse peri- and neonatal outcomes [ 3 , 12 , 13 ]. Several fetal and maternal features, such as fetal growth restriction, congenital anomaly, oligohydramnios, gestational diabetes, and previous cesarean section, are linked to a higher risk of breech presentation at term, and, furthermore, are associated with an increased risk for adverse perinatal outcomes [ 3 – 5 , 8 , 9 , 14 – 17 ].

The literature lacks studies on the risk factors of breech presentation in preterm pregnancies. It remains unclear whether breech presentation at preterm labor is only caused by the incomplete fetal rotation, or whether breech presentation in preterm labor is also associated with other obstetric risk factors. Most of the studies reviewing risk factors for breech presentation focus on term pregnancies. Our hypothesis is that breech presentation in preterm deliveries is, besides preterm pregnancy itself, associated with other risk factors similar to breech presentation at term. We aim to compare the risks of preterm breech presentation to those in cephalic presentation by gestational age. Such information would be valuable in the risk stratification of breech deliveries by gestational age.

Materials and methods

We conducted a retrospective population-based cross-sectional study. The population included all the singleton preterm and term births, from January 2004 to December 2014 in Finland. The data were collected from the national medical birth register and the hospital discharge register, maintained by the National Institute for Health and Welfare. All Finnish maternity hospitals are obligated to contribute clinical data on births from 22 weeks or birth weight of 500 g to the register. All newborn infants are examined by a pediatrician and given a personal identification number that can be traced in the case of perinatal mortality or morbidity. The hospital discharge register contains information on all surgical procedures and diagnoses (International Statistical Classification of Diseases and Related Health Problems 10th Revision, ICD-10) in all inpatient care and outpatient care in public hospitals.

Authorization to use the data was obtained from the National Institute for Health and Welfare as required by the national data protection law in Finland (reference number THL/652/5.05.00/2017).

The study population included all the women with a singleton fetus in breech presentation at the time of delivery. The control group included all the women with a singleton fetus in cephalic presentation at delivery. Other presentations were excluded from the study ( N  = 1671) (Fig.  1 ). Gestational age was determined according to early ultrasonographic measurement which is routinely performed in Finland and it encompasses over 95% of the mothers, or if not available, to the last menstrual period. We excluded neonates delivered before 24 weeks of gestation and birth weight of less than 500 g, because the lower viability may have influenced the mode of the delivery or the outcome. The study population was divided into four categories according to the World Health Organization (WHO) definitions of preterm and term deliveries. WHO defines preterm birth as a fetus born alive before 37 completed weeks of pregnancy. WHO recommends sub-categories of preterm birth, based on gestational age, as extremely preterm (less than 28 pregnancy weeks), very preterm (28–32 pregnancy weeks), and moderate to late preterm (32–37 pregnancy weeks).

Breech presentation for singleton pregnancies during the period of 2004–2014 in Finland

In our study, we assessed four factors that may be associated with breech presentation based on prior reports [ 3 – 5 , 14 , 17 – 20 ]. These factors were: maternal age below 25 and 35 years or more, smoking, pre-pregnancy body mass index (BMI) over 30, and in vitro fertilization. The following factors were also analyzed: nulliparity, more than three previous deliveries, and history of cesarean section. The obstetric risk factors including maternal hypo- or hyperthyroidism (ICD-10 E03, E05), gestational diabetes (ICD-10 O24.4) and other diabetes treated with insulin (ICD-10 O24.0), arterial hypertension or pre-eclampsia (ICD-10 O13, O14), and maternal care for (suspected) damage to fetus by alcohol or drugs (ICD-10 O35.4, O35.5) were assessed in the analysis. The variables that were also included in the analysis were: oligohydramnios (ICD-10 O41.0), placenta praevia (ICD-10 O44), placental abruption (ICD-10 O45), preterm premature rupture of membranes (PPROM) (ICD-10 O42), infant sex, fetal birth weight below the tenth percentile, fetuses with birth weight above the 97th percentile, and fetal congenital anomalies as defined in the register of congenital malformations.

The babies born in breech presentation from the four study groups were compared with the babies born in cephalic presentation with the equal gestational age, according to WHO classification. The calculations were performed using SPSS 19. Statistical differences in categorical variables were evaluated with the Chi-squared test or Fisher’s exact test when appropriate. We calculated odds ratios (ORs) with corresponding 95% confidence intervals (CIs) using binary logistic regression. Each study group was separately adjusted, according to gestational age at delivery, defined by WHO. The adjustment for the risk factors was done by multivariable logistic regression model for all variables. Differences were deemed to be statistically significant with P value < 0.05.

This analysis includes 737,788 singleton births, from these 20,086 were in breech presentation at the time of delivery. Out of all deliveries, 33,489 infants were born preterm. The prevalence of breech presentation at delivery decreased with the increase of the gestational age: 23.5% in extremely preterm delivery, 15.4% very preterm deliveries, and 6.7% in moderate to late preterm deliveries. At term, the prevalence of breech presentation at delivery was 2.5% (Fig.  1 ).

From all deliveries, 2056 fetuses were born extremely preterm (24 + 0 to 27 + 6 gestational weeks). The differences in the possible risk factors for breech presentation at delivery were higher odds of PPROM (aOR 1.39, 95% CI 1.08–1.79, P  = 0.010) and a lower risk of placental abruption (aOR 0.59, 95% CI 0.36–0.98, P  = 0.040). No statistically significant differences were observed for the other factors (Table ​ (Table1, 1 , Figs.  1 , ​ ,2, 2 , ​ ,3, 3 , ​ ,4 4 ).

The group of very preterm deliveries (28 + 0 to 31 + 6 gestational weeks) included 4582 singleton newborns. Breech presentation at delivery was associated with PPROM (aOR 1.61, 95% CI 1.32–1.96, P  < 0.001), oligohydramnios (aOR 1.65, 95% CI 1.03–2.64, P  = 0.038), fetal birth weight below the tenth percentile (aOR 1.57, 95% CI 1.19–2.08, P  = 0.002), and maternal pre-eclampsia and arterial hypertension (aOR 1.31, 95% CI 1.04–1.66, P  = 0.023). Details of risk factors in very preterm breech deliveries are described in Table ​ Table2. 2 . The risk of placenta praevia as well as having a birth weight above the 97th percentile was lower in pregnancies with fetuses in breech rather than in cephalic presentation (Table ​ (Table2, 2 , Figs. ​ Figs.2, 2 , ​ ,3, 3 , ​ ,4 4 ).

The moderate to late preterm delivery group (32 + 0 to 36 + 6 gestational weeks) included 26,851 deliveries. Breech presentation in moderate to late preterm deliveries was associated with older maternal age (maternal age 35 years or more aOR 1.24, 95% CI 1.10–1.39, P  < 0.001), nullipara (aOR 1.43, 95% CI 1.27–1.60, P  < 0.001), maternal BMI less than 25 (maternal BMI ≥ 25 aOR 0.75, 95% CI 0.62–0.91, P  = 0.004), previous cesarean section (aOR 1.31, 95% CI 1.12–1.53, P  < 0.001), female sex (aOR 1.22, 95% CI 1.11–1.34, P  < 0.001), congenital anomaly (aOR 1.37, 95% CI 1.22–1.55, P  < 0.001), fetal birth weight below the tenth percentile (aOR 1.31, 95% CI 1.10–1.56, P  = 0.003), oligohydramnios (aOR 3.60, 95% CI 2.63–4.92, P  < 0.001), and PPROM (aOR 1.58, 95% CI 1.41–1.78, P  < 0.001). Breech presentation decreased the odds of having a fetus with birth weight above the 97th percentile (aOR 0.60, 95% CI 0.42–0.85, P  = 0.004) (Table ​ (Table3, 3 , Figs. ​ Figs.2, 2 , ​ ,3, 3 , ​ ,4 4 ).

The term and post-term group included 704,299 deliveries, among them 17,044 fetuses in breech presentation. The factors associated with breech presentation amongst these were: maternal age of 35 years or more (aOR 1.24, 95% CI 1.19–1.29, P  < 0.001), nullipara (aOR 2.46, 95% CI 2.37–2.55, P  < 0.001), maternal BMI less than 25 (BMI ≥ 25 aOR 0.90, 95% CI 0.85–0.96, P  < 0.001), maternal hypothyroidism (aOR 1.53, 95% CI 1.28–1.82, P  < 0.001), pre-gestational diabetes treated with insulin (aOR 1.24, 95% CI 1.00–1.53, P  = 0.049), placenta praevia (aOR 1.45, 95% CI 1.11–1.91, P  = 0.007), premature rupture of membranes (PROM) (aOR 1.58, 95% CI 1.45–1.72, P  < 0.001), oligohydramnios (aOR 2.02, 95% CI 1.83–2.22, P  < 0.001), congenital anomaly (aOR 1.97, 95% CI 1.89–2.06, P  < 0.001), female sex (aOR 1.28, 95% CI 1.24–1.32, P  < 0.001), and birth weight below the tenth percentile (aOR 1.18, 95% CI 1.12–1.24, P  < 0.001) Table ​ Table4 4 includes details for risk factors of term and post-term group (Figs.  2 , ​ ,3, 3 , ​ ,4 4 ).

The main novel finding of our study was that the risk associations increase with each gestational age group after 28 weeks of gestation. With the exception of PPROM, the extremely preterm breech deliveries have similar clinical risk profiles as in cephalic presentation when matched for gestational age. However, as gestation proceeds, the risks start to cluster. In moderate to late preterm pregnancies as in term pregnancies, the breech presentation is a high-risk state being associated with several risk factors: PPROM, oligohydramnios, advanced maternal age, nulliparity, previous cesarean section, fetal birth weight below the tenth percentile, female sex, and fetal congenital anomalies. These are in line with the findings of previous studies [ 3 , 5 , 7 , 8 ], that associated breech presentation at term with obstetric risk factors. The prevalence of breech presentation was negatively correlated with the gestational age with a decline from 23.5% in extremely preterm pregnancies to 2.5% at term. The prevalence of breech presentation in preterm pregnancies observed in our trial is similar to that of comparable studies [ 1 , 2 ].

In extremely preterm deliveries, PPROM was the only risk factor for breech presentation and it stayed as a risk for breech presentation through the gestational weeks. This finding is comparable to the previous literature suggesting that PPROM occurs more often at earlier gestational age in pregnancies with the fetus in breech presentation compared with cephalic [ 21 , 22 ]. PPROM might prevent the fetus to change into cephalic presentation. Furthermore, Goodman and colleagues (2013) reported that in pregnancies with a fetus in a presentation other than cephalic had more complications such as oligohydramnios, infections, placental abruption, and even stillbirths. In our study, surprisingly, placental abruption seemed to have a negative correlation with breech presentation among extremely preterm deliveries. This inconsistency between our results and the literature might be due to the small number of cases. Many of the obstetric complications, for example gestational diabetes, late pre-eclampsia, and late intrauterine growth restriction develop during the second or the third trimester of the pregnancy which explains partially why the risk factors for breech presentation are rarer in extremely preterm deliveries.

In very preterm delivery, breech presentation was associated with PPROM, pre-eclampsia, and fetal birth weight below the tenth percentile. Fetal growth restriction is a known risk factor for breech presentation at term, since it is associated with reduced fetal movements due to diminished resources [ 23 – 25 ]. Furthermore, fetal growth restriction is known to be the single largest factor for stillbirth and neonatal mortality [ 26 – 30 ]. Maternal arterial hypertension disturbs placental function which might cause low birth weight [ 31 , 32 ]. Arterial hypertension and pre-eclampsia increased the risk for breech presentation in very preterm births, but not in earlier or later preterm pregnancies. This finding may be due to the bias that pre-eclampsia is a well-described risk factor for PPROM, fetal growth restriction, and preterm deliveries which are also independent markers for breech presentation itself [ 4 , 5 , 31 , 33 , 34 ]. The severity of early pre-eclampsia might affect the fetal wellbeing, reduce fetal movements and growth, which might reduce the spontaneous fetal rotation to the cephalic position [ 35 ]. In addition, the most severe cases might not reach older gestational age before the delivery.

The risk factor for breech presentation in moderate to late preterm breech delivery was PPROM, oligohydramnios, advanced maternal age, nulliparity, previous cesarean section, fetal birth weight below the tenth percentile, female sex, and fetal congenital anomalies. Oligohydramnios is a known significant risk factor for term breech pregnancies [ 25 ] and it is linked to the reduced fetal movements partly due to a restricted intrauterine space [ 24 , 35 ] and nuchal cords [ 35 ]. Additionally, oligohydramnios is associated with placental dysfunction, which might reduce fetal resources and thus has a progressive effect on the fetal movements and prevent the fetus from turning into cephalic presentation [ 3 , 4 , 18 ]. Fetal female sex in moderate to late preterm breech pregnancies remained as a risk factor, as identified previously for term pregnancies [ 3 – 5 ]. It has been debated whether this risk is due to a smaller fetal size or that female fetuses tend to move less [ 9 , 20 ]. The mothers of infants born in breech presentation in moderate to late preterm and term and post-term pregnancies seemed to be older and had an increased risk of having a fetus with a congenital anomaly. The advanced maternal age is associated with negative effects on vascular health, which may have an influence on the developing fetus and increase the incidence of congenital anomalies [ 19 , 34 , 36 ]. Furthermore, congenital anomalies may have a negative influence on fetal movements [ 19 , 35 ]. Whereas, the low birth weight was found as a risk for breech presentation, a birth weight above the 97th percentile was, coherently a protective factor for breech presentation in very to term and post-term pregnancies.

We found that in term pregnancies, breech presentation was associated with advanced maternal age, nulliparity, maternal hypothyroidism, pre-gestational diabetes, placenta praevia, PROM, oligohydramnios, fetal congenital anomaly, female sex of the fetus, and birth weight below the tenth percentile. A previous cesarean section is known to be positively related to the odds of having a fetus in breech presentation at term [ 5 , 14 ], and in our study, this risk factor started to show already in moderate to late preterm pregnancies. Instead of the scar being the cause of breech presentation, it is more likely that the women with a history of breech cesarean section have, during subsequent pregnancies, a fetus in breech presentation again or have a cesarean section for another reason [ 3 , 5 , 37 ]. Our data suggest that the advanced maternal age and nulliparity are the risks for breech presentation at term, but as well as in moderate to late preterm pregnancies. The tight wall of the abdomen and the uterus of nulliparous women might inhibit the fetus from rotating to cephalic presentation [ 9 ]. In a meta-analysis from 2017, older maternal age has been considered to increase the risk of placental dysfunction such as pre-eclampsia and preterm birth [ 36 ] that are also common risk factors for breech presentation [ 4 , 5 ]. Bearing the first child in older maternal age and giving birth by cesarean section may affect the decision not to have another child and might explain the higher rate of nulliparity among moderate to late preterm and term deliveries [ 1 ]. Our study found correlation between maternal hypothyroidism and breech presentation at term. Some studies have demonstrated an association between maternal thyroid hypofunction and adverse pregnancy outcomes such as pre-eclampsia and low birth weight which are, furthermore, risks for breech presentation and may explain partly the higher prevalence of maternal hypothyroidism in term breech deliveries [ 38 – 40 ]. However, the absence of screening of, for example, thyroid diseases may cause bias in the diagnoses.

Our study demonstrated that as gestation proceeds, more obstetric risk factors can be found associating with breech presentation. In the earlier gestation and excluding PPROM, breech deliveries did not differ in obstetric risk factors compared to cephalic. The risk factors in 32 weeks of gestational age are comparable to those in term pregnancy, and several of these factors, such as low birth weight, congenital anomalies and history of cesarean section, are associated with adverse fetal outcomes [ 1 , 4 , 5 , 8 , 14 , 17 ] and must be taken into account when treating breech pregnancies. Risk factors should be evaluated prior to offering a patient an external cephalic version, as the presence of some of these risks may increase the change of failed version or fetal intolerance of the procedure. This study had adequate power to show differences between the risk profiles of breech and cephalic presentations in different gestational phase. Further research, however, is needed for improving the identification of patients at risk for preterm breech labor and elucidating the optimal route for delivery in preterm breech pregnancies.

Our study is unique since it is the first study, to our knowledge, that compares the risks for breech presentation in preterm and term deliveries. The analysis is based on a large nationwide population, which is the major strength of our study. The study population included nearly 34,000 preterm births over 11 years in Finland and 737,788 deliveries overall. The medical treatment of pregnancies is homogenous, since there are no private hospitals treating deliveries. A further strength relates to the important information on the characteristics of the mother, for example smoking during pregnancy and pre-pregnancy body mass index. The retrospective approach is a limitation of the study, another one is the design as a record linkage study, due to which the variables were restricted to the data availability. Therefore, we were not able to assess, for example uterine anomalies or previous breech deliveries to the analysis.

Our results show that the factors associated with breech presentation in very late preterm breech deliveries resemble those in term pregnancies. However, breech presentation in extremely preterm breech birth has similar clinical risk profiles as in cephalic presentation.

Breech Presentation: What It Is and How It Can Affect Your Baby's Delivery

As you get close to your due date, your baby might sense she’s approaching her grand entrance and move into a head-down position in your uterus, ready to be born. However, in some cases, she might choose another position instead, such as bottom or feet down. When this happens, it’s called a breech presentation. Read on to learn how your healthcare provider checks the position of your baby, what delivery options you may have if your baby is breech, and what can cause a breech presentation.

What Is Breech?

During your pregnancy, your baby has likely taken every opportunity to let you know she means business by kicking up a storm and doing countless somersaults. It's natural for your baby to move and shift positions within the uterus. Then, usually between 32 and 36 weeks of pregnancy, your baby will likely get into a head-down position in preparation for being born.

There is a small chance — just 3 to 4 percent — that your baby may not move into this head-down position by the time your pregnancy is full term. This is called a breech presentation. The chance of a breech presentation is higher if your pregnancy is not yet full term or if you go into preterm labor .

Types of Birth Positions

There are many different types of positions, including a number of breech presentations, that your baby may take on before birth:

Frank breech presentation. Your baby's bottom is positioned downward. This is the most common type of breech presentation.

Complete breech presentation. Your baby's feet are positioned downward with her hips and knees flexed, almost cross-legged.

Incomplete breech presentation. Your baby's feet are positioned downward with only one hip or one knee flexed.

Shoulder presentation or transverse lie. This is a form of breech in which your baby is positioned horizontally in the uterus. Few babies remain this way at the time of delivery.

Footling breech. One or both of your baby's feet are pointed downward.

Cephalic or vertex presentation (occiput). Your baby is in the normal position for delivery. Her head is down and she’s facing toward your back.

Cephalic or vertex presentation (occiput posterior). In some cases, your baby may be in a downward position but with her face toward your front. If this happens in early labor, your baby may naturally turn to face your back on her own, or, later in labor, your provider may decide to manually assist the baby in getting into this position. If this doesn't work, your baby can still be delivered vaginally, but delivery may be prolonged and more painful.

The causes of your baby being in breech position aren't always clear, but it can be more common if any of the following apply to you:

You've been pregnant before

You are pregnant with twins (read on to learn more about twin breech)

The uterus has more or less amniotic fluid than usual

The uterus has an abnormal shape or has abnormal growths, such as fibroids.

You have a condition called placenta previa , which is when the placenta covers the cervix.

Your healthcare provider likely already knows whether any of these factors affect your situation, but you might want to mention it just to be sure.

Diagnosis of a Breech Presentation

At one of your prenatal visits in the lead up to your due date, your provider will check that everything is progressing as planned , and will examine your abdomen to try to find out whether your baby is in the correct head-down position. If your provider thinks there may be a breech presentation, she or he may recommend an ultrasound exam to confirm it.

Can a Breech Baby Be Turned?

If your baby is breech, your provider may consider turning your baby so that a vaginal delivery can proceed, if that’s in the cards for you anyway. Alternatively, your provider may recommend that a cesarean delivery is the safer option.

Keep in mind, your baby's position might change at some point before delivery day, so your provider may recommend waiting and seeing.

If you are 37 weeks pregnant or more, your provider may recommend turning your baby through a process called external cephalic version or ECV.

ECV involves your provider placing hands on your abdomen and applying firm pressure in order to turn the baby. This procedure will most likely be done near a delivery room. Your provider may offer an epidural block to help with any pain this procedure causes.

An ECV is about 50 percent effective and there is a small risk of complications. You and your baby will be monitored closely before, during, and after the procedure to ensure that both of you are doing well.

If the ECV procedure is successful, your baby can be delivered vaginally , if there’s no other impediment.

Delivery Options for a Breech Baby

If your baby is in a breech position, the risks associated with a vaginal delivery are much higher than with a cesarean section. Risks include the umbilical cord cutting off his blood supply or his head or shoulders becoming stuck. That’s why, in some cases, your provider may recommend a cesarean delivery .

It could be that your provider’s level of experience in delivering breech babies might also inform the discussion you have with your provider about what’s right for your situation. Ultimately, your provider will recommend the best course of action for you and your baby based on your personal situation.

Twins and Breech Presentation

It's possible for twins to be delivered vaginally if the first baby — the lower-positioned twin — is correctly positioned with the head facing down. Of course, that's if the twin pregnancy is otherwise progressing well and there are no complications. If the second twin is in a breech position, the provider may do an ECV procedure to get this baby in the correct head-down position for a vaginal delivery, too.

If the first twin baby (the one lower down) is in a breech position, the provider may recommend a cesarean section. Triplets or more will most likely require a cesarean section.

Although you might feel like the added stress of a breech baby is the last thing you need as you approach your due date, remember that your healthcare provider has seen this situation before and will know what to do to ensure your baby is delivered safely. Next thing you know, you'll be bringing your brand-new baby home , stocking up on diapers, waking up for late-night feedings, and reveling in your baby's growth .

Where You Already Belong

What happens if your baby is breech?

Babies often twist and turn during pregnancy, but most will have moved into the head-down (also known as head-first) position by the time labour begins. However, that does not always happen, and a baby may be:

• bottom first or feet first (breech position)
• lying sideways (transverse position)

Bottom first or feet first (breech baby)

If your baby is lying bottom or feet first, they are in the breech position. If they're still breech at around 36 weeks' gestation, the obstetrician and midwife will discuss your options for a safe delivery.

Turning a breech baby

If your baby is in a breech position at 36 weeks, you'll usually be offered an external cephalic version (ECV). This is when a healthcare professional, such as an obstetrician, tries to turn the baby into a head-down position by applying pressure on your abdomen. It's a safe procedure, although it can be a bit uncomfortable.

Giving birth to a breech baby

If an ECV does not work, you'll need to discuss your options for a vaginal birth or  caesarean section  with your midwife and obstetrician.

If you plan a caesarean and then go into labour before the operation, your obstetrician will assess whether it's safe to proceed with the caesarean delivery. If the baby is close to being born, it may be safer for you to have a vaginal breech birth.

The Royal College of Obstetricians and Gynaecologists (RCOG) website has more information on what to expect if your baby is still breech at the end of pregnancy .

The RCOG advises against a vaginal breech delivery if:

• your baby's feet are below its bottom – known as a "footling breech"
• your baby is larger or smaller than average – your healthcare team will discuss this with you
• your baby is in a certain position – for example, their neck is very tilted back, which can make delivery of the head more difficult
• you have a low-lying placenta (placenta praevia)

Lying sideways (transverse baby)

If your baby is lying sideways across the womb, they are in the transverse position. Although many babies lie sideways early on in pregnancy, most turn themselves into the head-down position by the final trimester.

Giving birth to a transverse baby

Depending on how many weeks pregnant you are when your baby is in a transverse position, you may be admitted to hospital. This is because of the very small risk of the umbilical cord coming out of your womb before your baby is born (cord prolapse). If this happens, it's a medical emergency and the baby must be delivered very quickly.

Sometimes, it's possible to manually turn the baby to a head-down position, and you may be offered this.

But, if your baby is still in the transverse position when you approach your due date or by the time labour begins, you'll most likely be advised to have a caesarean section.

Learning Objectives

• Explain how estrogen, progesterone, and hCG are involved in maintaining pregnancy
• List the contributors to weight gain during pregnancy
• Describe the major changes to the maternal digestive, circulatory, and integumentary systems during pregnancy
• Summarize the events leading to labor
• Identify and describe each of the three stages of childbirth

A full-term pregnancy lasts approximately 270 days (approximately 38.5 weeks) from conception to birth. Because it is easier to remember the first day of the last menstrual period (LMP) than to estimate the date of conception, obstetricians set the due date as 284 days (approximately 40.5 weeks) from the LMP. This assumes that conception occurred on day 14 of the woman’s cycle, which is usually a good approximation. The 40 weeks of an average pregnancy are usually discussed in terms of three trimesters , each approximately 13 weeks. During the second and third trimesters, the pre-pregnancy uterus—about the size of a fist—grows dramatically to contain the fetus, causing a number of anatomical changes in the mother (Figure \(\PageIndex{1}\)).

Effects of Hormones

Virtually all of the effects of pregnancy can be attributed in some way to the influence of hormones—particularly estrogens, progesterone, and hCG. During weeks 7–12 from the LMP, the pregnancy hormones are primarily generated by the corpus luteum. Progesterone secreted by the corpus luteum stimulates the production of decidual cells of the endometrium that nourish the blastocyst before placentation. As the placenta develops and the corpus luteum degenerates during weeks 12–17, the placenta gradually takes over as the endocrine organ of pregnancy.

The placenta converts weak androgens secreted by the maternal and fetal adrenal glands to estrogens, which are necessary for pregnancy to progress. Estrogen levels climb throughout the pregnancy, increasing 30-fold by childbirth. Estrogens have the following actions:

• They suppress FSH and LH production, effectively preventing ovulation. (This function is the biological basis of hormonal birth control pills.)
• They induce the growth of fetal tissues and are necessary for the maturation of the fetal lungs and liver.
• They promote fetal viability by regulating progesterone production and triggering fetal synthesis of cortisol, which helps with the maturation of the lungs, liver, and endocrine organs such as the thyroid gland and adrenal gland.
• They stimulate maternal tissue growth, leading to uterine enlargement and mammary duct expansion and branching.

Relaxin, another hormone secreted by the corpus luteum and then by the placenta, helps prepare the mother’s body for childbirth. It increases the elasticity of the symphysis pubis joint and pelvic ligaments, making room for the growing fetus and allowing expansion of the pelvic outlet for childbirth. Relaxin also helps dilate the cervix during labor.

The placenta takes over the synthesis and secretion of progesterone throughout pregnancy as the corpus luteum degenerates. Like estrogen, progesterone suppresses FSH and LH. It also inhibits uterine contractions, protecting the fetus from preterm birth. This hormone decreases in late gestation, allowing uterine contractions to intensify and eventually progress to true labor. The placenta also produces hCG. In addition to promoting survival of the corpus luteum, hCG stimulates the male fetal gonads to secrete testosterone, which is essential for the development of the male reproductive system.

The anterior pituitary enlarges and ramps up its hormone production during pregnancy, raising the levels of thyrotropin, prolactin, and adrenocorticotropic hormone (ACTH). Thyrotropin, in conjunction with placental hormones, increases the production of thyroid hormone, which raises the maternal metabolic rate. This can markedly augment a pregnant woman’s appetite and cause hot flashes. Prolactin stimulates enlargement of the mammary glands in preparation for milk production. ACTH stimulates maternal cortisol secretion, which contributes to fetal protein synthesis. In addition to the pituitary hormones, increased parathyroid levels mobilize calcium from maternal bones for fetal use.

Weight Gain

The second and third trimesters of pregnancy are associated with dramatic changes in maternal anatomy and physiology. The most obvious anatomical sign of pregnancy is the dramatic enlargement of the abdominal region, coupled with maternal weight gain. This weight results from the growing fetus as well as the enlarged uterus, amniotic fluid, and placenta. Additional breast tissue and dramatically increased blood volume also contribute to weight gain (Table \(\PageIndex{1}\)). Surprisingly, fat storage accounts for only approximately 2.3 kg (5 lbs) in a normal pregnancy and serves as a reserve for the increased metabolic demand of breastfeeding.

During the first trimester, the mother does not need to consume additional calories to maintain a healthy pregnancy. However, a weight gain of approximately 0.45 kg (1 lb) per month is common. During the second and third trimesters, the mother’s appetite increases, but it is only necessary for her to consume an additional 300 calories per day to support the growing fetus. Most women gain approximately 0.45 kg (1 lb) per week.

Table \(\PageIndex{1}\)

Changes in Organ Systems During Pregnancy

As the woman’s body adapts to pregnancy, characteristic physiologic changes occur. These changes can sometimes prompt symptoms often referred to collectively as the common discomforts of pregnancy.

Digestive and Urinary System Changes

Nausea and vomiting, sometimes triggered by an increased sensitivity to odors, are common during the first few weeks to months of pregnancy. This phenomenon is often referred to as “morning sickness,” although the nausea may persist all day. The source of pregnancy nausea is thought to be the increased circulation of pregnancy-related hormones, specifically circulating estrogen, progesterone, and hCG. Decreased intestinal peristalsis may also contribute to nausea. By about week 12 of pregnancy, nausea typically subsides.

A common gastrointestinal complaint during the later stages of pregnancy is gastric reflux, or heartburn, which results from the upward, constrictive pressure of the growing uterus on the stomach. The same decreased peristalsis that may contribute to nausea in early pregnancy is also thought to be responsible for pregnancy-related constipation as pregnancy progresses.

The downward pressure of the uterus also compresses the urinary bladder, leading to frequent urination. The problem is exacerbated by increased urine production. In addition, the maternal urinary system processes both maternal and fetal wastes, further increasing the total volume of urine.

Circulatory System Changes

Blood volume increases substantially during pregnancy, so that by childbirth, it exceeds its preconception volume by 30 percent, or approximately 1–2 liters. The greater blood volume helps to manage the demands of fetal nourishment and fetal waste removal. In conjunction with increased blood volume, the pulse and blood pressure also rise moderately during pregnancy. As the fetus grows, the uterus compresses underlying pelvic blood vessels, hampering venous return from the legs and pelvic region. As a result, many pregnant women develop varicose veins or hemorrhoids.

Respiratory System Changes

During the second half of pregnancy, the respiratory minute volume (volume of gas inhaled or exhaled by the lungs per minute) increases by 50 percent to compensate for the oxygen demands of the fetus and the increased maternal metabolic rate. The growing uterus exerts upward pressure on the diaphragm, decreasing the volume of each inspiration and potentially causing shortness of breath, or dyspnea. During the last several weeks of pregnancy, the pelvis becomes more elastic, and the fetus descends lower in a process called lightening . This typically ameliorates dyspnea.

The respiratory mucosa swell in response to increased blood flow during pregnancy, leading to nasal congestion and nose bleeds, particularly when the weather is cold and dry. Humidifier use and increased fluid intake are often recommended to counteract congestion.

Integumentary System Changes

The dermis stretches extensively to accommodate the growing uterus, breast tissue, and fat deposits on the thighs and hips. Torn connective tissue beneath the dermis can cause striae (stretch marks) on the abdomen, which appear as red or purple marks during pregnancy that fade to a silvery white color in the months after childbirth.

An increase in melanocyte-stimulating hormone, in conjunction with estrogens, darkens the areolae and creates a line of pigment from the umbilicus to the pubis called the linea nigra (Figure \(\PageIndex{2}\)). Melanin production during pregnancy may also darken or discolor skin on the face to create a chloasma, or “mask of pregnancy.”

Physiology of Labor

Childbirth, or parturition , typically occurs within a week of a woman’s due date, unless the woman is pregnant with more than one fetus, which usually causes her to go into labor early. As a pregnancy progresses into its final weeks, several physiological changes occur in response to hormones that trigger labor.

First, recall that progesterone inhibits uterine contractions throughout the first several months of pregnancy. As the pregnancy enters its seventh month, progesterone levels plateau and then drop. Estrogen levels, however, continue to rise in the maternal circulation (Figure \(\PageIndex{3}\)). The increasing ratio of estrogen to progesterone makes the myometrium (the uterine smooth muscle) more sensitive to stimuli that promote contractions (because progesterone no longer inhibits them). Moreover, in the eighth month of pregnancy, fetal cortisol rises, which boosts estrogen secretion by the placenta and further overpowers the uterine-calming effects of progesterone. Some women may feel the result of the decreasing levels of progesterone in late pregnancy as weak and irregular peristaltic Braxton Hicks contractions , also called false labor. These contractions can often be relieved with rest or hydration.

A common sign that labor will be short is the so-called “bloody show.” During pregnancy, a plug of mucus accumulates in the cervical canal, blocking the entrance to the uterus. Approximately 1–2 days prior to the onset of true labor, this plug loosens and is expelled, along with a small amount of blood.

Meanwhile, the posterior pituitary has been boosting its secretion of oxytocin, a hormone that stimulates the contractions of labor. At the same time, the myometrium increases its sensitivity to oxytocin by expressing more receptors for this hormone. As labor nears, oxytocin begins to stimulate stronger, more painful uterine contractions, which—in a positive feedback loop—stimulate the secretion of prostaglandins from fetal membranes. Like oxytocin, prostaglandins also enhance uterine contractile strength. The fetal pituitary also secretes oxytocin, which increases prostaglandins even further. Given the importance of oxytocin and prostaglandins to the initiation and maintenance of labor, it is not surprising that, when a pregnancy is not progressing to labor and needs to be induced, a pharmaceutical version of these compounds (called pitocin) is administered by intravenous drip.

Finally, stretching of the myometrium and cervix by a full-term fetus in the vertex (head-down) position is regarded as a stimulant to uterine contractions. The sum of these changes initiates the regular contractions known as true labor , which become more powerful and more frequent with time. The pain of labor is attributed to myometrial hypoxia during uterine contractions.

Stages of Childbirth

The process of childbirth can be divided into three stages: cervical dilation, expulsion of the newborn, and afterbirth (Figure \(\PageIndex{4}\)).

Cervical Dilation

For vaginal birth to occur, the cervix must dilate fully to 10 cm in diameter—wide enough to deliver the newborn’s head. The dilation stage is the longest stage of labor and typically takes 6–12 hours. However, it varies widely and may take minutes, hours, or days, depending in part on whether the mother has given birth before; in each subsequent labor, this stage tends to be shorter.

True labor progresses in a positive feedback loop in which uterine contractions stretch the cervix, causing it to dilate and efface, or become thinner. Cervical stretching induces reflexive uterine contractions that dilate and efface the cervix further. In addition, cervical dilation boosts oxytocin secretion from the pituitary, which in turn triggers more powerful uterine contractions. When labor begins, uterine contractions may occur only every 3–30 minutes and last only 20–40 seconds; however, by the end of this stage, contractions may occur as frequently as every 1.5–2 minutes and last for a full minute.

Each contraction sharply reduces oxygenated blood flow to the fetus. For this reason, it is critical that a period of relaxation occur after each contraction. Fetal distress, measured as a sustained decrease or increase in the fetal heart rate, can result from severe contractions that are too powerful or lengthy for oxygenated blood to be restored to the fetus. Such a situation can be cause for an emergency birth with vacuum, forceps, or surgically by Caesarian section.

The amniotic membranes rupture before the onset of labor in about 12 percent of women; they typically rupture at the end of the dilation stage in response to excessive pressure from the fetal head entering the birth canal.

Expulsion Stage

The expulsion stage begins when the fetal head enters the birth canal and ends with birth of the newborn. It typically takes up to 2 hours, but it can last longer or be completed in minutes, depending in part on the orientation of the fetus. The vertex presentation known as the occiput anterior vertex is the most common presentation and is associated with the greatest ease of vaginal birth. The fetus faces the maternal spinal cord and the smallest part of the head (the posterior aspect called the occiput) exits the birth canal first.

In fewer than 5 percent of births, the infant is oriented in the breech presentation, or buttocks down. In a complete breech, both legs are crossed and oriented downward. In a frank breech presentation, the legs are oriented upward. Before the 1960s, it was common for breech presentations to be delivered vaginally. Today, most breech births are accomplished by Caesarian section.

Vaginal birth is associated with significant stretching of the vaginal canal, the cervix, and the perineum. Until recent decades, it was routine procedure for an obstetrician to numb the perineum and perform an episiotomy , an incision in the posterior vaginal wall and perineum. The perineum is now more commonly allowed to tear on its own during birth. Both an episiotomy and a perineal tear need to be sutured shortly after birth to ensure optimal healing. Although suturing the jagged edges of a perineal tear may be more difficult than suturing an episiotomy, tears heal more quickly, are less painful, and are associated with less damage to the muscles around the vagina and rectum.

Upon birth of the newborn’s head, an obstetrician will aspirate mucus from the mouth and nose before the newborn’s first breath. Once the head is birthed, the rest of the body usually follows quickly. The umbilical cord is then double-clamped, and a cut is made between the clamps. This completes the second stage of childbirth.

The delivery of the placenta and associated membranes, commonly referred to as the afterbirth , marks the final stage of childbirth. After expulsion of the newborn, the myometrium continues to contract. This movement shears the placenta from the back of the uterine wall. It is then easily delivered through the vagina. Continued uterine contractions then reduce blood loss from the site of the placenta. Delivery of the placenta marks the beginning of the postpartum period—the period of approximately 6 weeks immediately following childbirth during which the mother’s body gradually returns to a non-pregnant state. If the placenta does not birth spontaneously within approximately 30 minutes, it is considered retained, and the obstetrician may attempt manual removal. If this is not successful, surgery may be required.

It is important that the obstetrician examines the expelled placenta and fetal membranes to ensure that they are intact. If fragments of the placenta remain in the uterus, they can cause postpartum hemorrhage. Uterine contractions continue for several hours after birth to return the uterus to its pre-pregnancy size in a process called involution , which also allows the mother’s abdominal organs to return to their pre-pregnancy locations. Breastfeeding facilitates this process.

Although postpartum uterine contractions limit blood loss from the detachment of the placenta, the mother does experience a postpartum vaginal discharge called lochia . This is made up of uterine lining cells, erythrocytes, leukocytes, and other debris. Thick, dark, lochia rubra (red lochia) typically continues for 2–3 days, and is replaced by lochia serosa, a thinner, pinkish form that continues until about the tenth postpartum day. After this period, a scant, creamy, or watery discharge called lochia alba (white lochia) may continue for another 1–2 weeks.

Chapter Review

Hormones (especially estrogens, progesterone, and hCG) secreted by the corpus luteum and later by the placenta are responsible for most of the changes experienced during pregnancy. Estrogen maintains the pregnancy, promotes fetal viability, and stimulates tissue growth in the mother and developing fetus. Progesterone prevents new ovarian follicles from developing and suppresses uterine contractility.

Pregnancy weight gain primarily occurs in the breasts and abdominal region. Nausea, heartburn, and frequent urination are common during pregnancy. Maternal blood volume increases by 30 percent during pregnancy and respiratory minute volume increases by 50 percent. The skin may develop stretch marks and melanin production may increase.

Toward the late stages of pregnancy, a drop in progesterone and stretching forces from the fetus lead to increasing uterine irritability and prompt labor. Contractions serve to dilate the cervix and expel the newborn. Delivery of the placenta and associated fetal membranes follows.

Critical Thinking Questions

Q. Devin is 35 weeks pregnant with her first child when she arrives at the birthing unit reporting that she believes she is in labor. She states that she has been experiencing diffuse, mild contractions for the past few hours. Examination reveals, however, that the plug of mucus blocking her cervix is intact and her cervix has not yet begun to dilate. She is advised to return home. Why?

A. Devin is very likely experiencing Braxton Hicks contractions, also known as false labor. These are mild contractions that do not promote cervical dilation and are not associated with impending birth. They will probably dissipate with rest.

Q. Janine is 41 weeks pregnant with her first child when she arrives at the birthing unit reporting that she believes she has been in labor “for days” but that “it’s just not going anywhere.” During the clinical exam, she experiences a few mild contractions, each lasting about 15–20 seconds; however, her cervix is found to be only 2 cm dilated, and the amniotic sac is intact. Janine is admitted to the birthing unit and an IV infusion of pitocin is started. Why?

A. Janine is 41 weeks pregnant, and the mild contractions she has been experiencing “for days” have dilated her cervix to 2 cm. These facts suggest that she is in labor, but that the labor is not progressing appropriately. Pitocin is a pharmaceutical preparation of synthetic prostaglandins and oxytocin, which will increase the frequency and strength of her contractions and help her labor to progress to birth.

Shoulder Presentation – Everything You Should Be Aware Of

Image: Shutterstock

Vaginal delivery is the best way to bring your baby out, but it is not always an easy option. The position of the fetus is crucial as any deviation in this can lead to complications.

Shoulder presentation is a rare but a complicated instance when normal delivery becomes almost impossible. Read below to know more about this phenomenon, its diagnosis and the options you have when you face this situation.

What Is Shoulder Presentation:

Shoulder presentation happens when that part of the fetus pushes out of the mother’s body first. This may occur when the fetus is positioned transversely across the uterus.

In a shoulder presentation, a baby cannot be delivered through the natural way but only through Caesarean section because vaginal delivery is possible only if the baby’s head or feet/buttock are at the bottom. If the baby is facing downwards, its hand may appear through the cervix, and if it is facing upwards, its back may be visible.

[ Read: Brow Presentation And Its Complications ]

What Is Transverse Lie:

When the long axis of the fetus lies perpendicular to the maternal spine or uterine axis, it is called a transverse lie. When the fetal axis is slanted to the maternal spine, it is known as an oblique lie. In both the conditions, the shoulder presents over the cervical opening during labor.

Frequency Of Shoulder Representation:

Shoulder presentation is a rare condition and occurs among one in 300 births. It is common in macerated and premature fetuses and five times more frequent in multiparae than in primigravidae.

Causes Of Shoulder Presentation:

Shoulder presentation can be the result of various fetal or maternal factors.

The fetal factors include:

• Multiple pregnancies
• Preterm labor
• Polyhydramnios, a condition in which the fetus can move freely in excessive water
• Placenta previa, which prevents the head from entering the pelvic brim
• Intrauterine fetal death
• Macerated fetus, the lack of muscle tone, which causes the fetus to fall into the lower portion of the uterus.

[ Read: How To Push During Delivery ]

The maternal factors include:

• Uterine abnormality such as sub-septate and fibroid uterus and bicornuate
• Pelvic masses as ovarian tumors
• Lax uterine and abdominal muscles. It usually occurs in the case of multiple pregnancies.
• Contracted or abnormally narrow pelvis

What Are the Complications Of Shoulder Presentation?

• Trauma to a prolapsed arm
• Cord prolapse
• Ruptured uterus and obstructed labor
• Fetal hypoxia or even death

Diagnosis Of Shoulder Presentation:

• The most common diagnosis of shoulder presentation is the uterus becoming broader on abdominal palpation.
• The height of the fundus reduces because it is occupied by neither the buttock nor baby’s head.
• The expectant mother can feel the head on one side of her abdomen.
• On vaginal examination, especially during early labor, the presenting part may not be felt by the mother, but when it progresses, she can feel the baby’s ribs.
• If the shoulder enters the pelvic brim, the arm may become visible outside the vagina because of arms prolapse.

Management Of Shoulder Presentation:

Traverse lie can be versed in a longitudinal line before labor, but once the uterus starts contracting, it will not allow for any such procedures. Here are the different ways to manage shoulder presentation.

1. External cephalic version:

• The external cephalic version of shoulder presentation should be done in cases beyond 35 weeks, and only if the membranes are intact, and the vaginal delivery is feasible.
• The patient has to be admitted at 37 weeks when the risk of membranes and cord rupture prolapse. In such a case, Caesarean section is the preferred mode of delivery.
• Vaginal delivery can be allowed in the malformed or dead fetus. Labor must be permitted under full supervision, by destructive operation or internal version.

External cephalic version is done both during early and late labor.

Early Labor:

• External cephalic version can be done during early labor when a good amount of amnii is present. Doctors suggest a Caesarean section in early labor.

Late Labor:

• In the case of late labor, if the fetal condition is good and the baby is mature, Caesarean section is preferred. The internal version should be done only in the event of the second twin.
• For stillborn babies, Caesarean-section is preferred. If destruction operation needs to be done, the uterine cavity should be explored to avoid the rupture of the uterus.

2. Internal Podalic Version:

Internal Podalic Version is indicated in case of the second twin of a transverse lie, followed by breech extraction.

The prerequisites for internal podalic version include:

• Dilated Cervix
• Just ruptured or intact cervix
• Epidural or general anesthesia

3. Caesarean Section:

• Caesarean section is the safest management method in nearly all the cases of persistent transverse or oblique lie.
• Rupture of membranes can lead to cord prolapse. Elective Caesarean section should be planned before the commencement of labor.
• Remember, in shoulder presentation, the baby cannot be born through the vagina. So if you detect this anomaly, consult a specialist immediately.
