Breech birth

Pregnancy - breech; Delivery - breech

The best position for your baby inside your uterus at the time of delivery is head down. This position makes it easier and safer for your baby to pass through the birth canal.

In the last weeks of pregnancy, your health care provider will check to see what position your baby is in.

If your baby's position does not feel normal, you may need an ultrasound. If the ultrasound shows your baby is breech, your provider will talk with you about your options for a safe delivery.

What is Breech?

In breech position, the baby's bottom is down. There are a few types of breech:

Complete breech means the baby is bottom-first, with knees bent.
Frank breech means the baby's legs are stretched up, with feet near the head.
Footling breech means one leg is lowered over the mother's cervix.

You are more likely to have a breech baby if you:

Go into early labor
Have an abnormally shaped uterus, fibroids, or too much amniotic fluid
Have more than one baby in your womb
Have placenta previa (when the placenta is on the lower part of the uterine wall, blocking the cervix)

Turning Your Baby (External Version)

If your baby is not in a head-down position after your 36th week, your provider can explain your choices and their risks to help you decide what steps to take next.

Your provider may offer to try to guide the baby into the right position. This is called external version. It involves pushing on your belly while watching the baby on an ultrasound. The pushing may cause some discomfort.

If your provider tries to change your baby's position, you may be given a medicine that relaxes the muscles of your uterus. You can also expect:

An ultrasound to show your provider where the placenta and baby are located.
Your provider to push on your abdomen to try and turn your baby's position.
Your baby's heartbeat to be monitored.

Success is higher if your provider tries this procedure at about 35 to 37 weeks. At this time, your baby is a little smaller, and there is most often more fluid around the baby. Your baby is also old enough in case there is a problem during the procedure that makes it necessary to deliver the baby promptly. This is rare. External version cannot be done once you are in active labor.

Risks are low for this procedure when a skilled provider does it. Rarely, it may lead to an emergency cesarean birth (C-section) if:

Part of the placenta tears away from the lining of your womb
Your baby's heartbeat drops too low, which can happen if the umbilical cord is tightly wrapped around your baby

If My Baby Doesn't Turn, Will I Have a C-section?

Most babies who remain breech after an attempt at turning them will be delivered by C-section. Your provider will explain the risk of delivering a breech baby vaginally.

Today, the option to deliver a breech baby vaginally is not offered in most cases. The safest way for a breech baby to be born is by C-section.

The danger of breech birth is mostly due to the fact that the largest part of a baby is its head. When the breech baby's pelvis or hips deliver first, the woman's pelvis may not be large enough for the head to be delivered also. This can result in a baby getting stuck in the birth canal, which can cause injury or death.

The umbilical cord may also be damaged or blocked. This can reduce the baby's oxygen supply.

If a C-section is planned, it will most often be scheduled for no earlier than 39 weeks. You will have an ultrasound at the hospital to confirm the position of your baby just before the surgery.

There is also a chance that you will go into labor or your water will break before your planned C-section. If that happens, call your provider right away and go to the hospital. It is important to go in right away if you have a breech baby and your bag of water breaks. This is because there is a higher chance that the cord will come out even before you are in labor. This can be very dangerous for your baby.

Presentation

<strong>Breech - series</strong><p>The term fetal presentation refers to the part of your baby's body that is closest to the birth canal. In most full-term pregnancies, the baby is positioned head down, or cephalic, in the uterus.</p>

<strong>Breech presentation</strong><p>If your baby is breech, his bottom is the part of his body closest to the birth canal. No one is sure what causes a breech presentation, but it happens in 3% to 5% of single-baby deliveries. As your pregnancy nears full term, your caregiver will check your baby's position during regular prenatal visits. Common methods for assessing fetal position include vaginal exams, ultrasound, feeling your abdomen, and listening to the baby's heartbeat with a Doppler device.</p>

<strong>Types of breech presentation</strong><p>There are three types of breech presentation complete, incomplete, and frank. Complete breech is when both of the baby's knees are bent and his feet and bottom are closest to the birth canal. Incomplete breech is when one of the baby's knees is bent and his foot and bottom are closest to the birth canal. Frank breech is when the baby's legs are folded flat up against his head and his bottom is closest to the birth canal. There is also footling breech where one or both feet are presenting.</p>

<strong>Complications of breech</strong><p>A prolapsed umbilical cord is common in breech deliveries. This happens when part of the umbilical cord slips down through the cervix before the baby does. The cord is then compressed during contractions, which cuts down on blood flow to the baby. An emergency cesarean section is usually needed.</p>

<strong>Correcting breech</strong><p>If you are near term and your baby is breech, your doctor may try to manually move him into a head-down position for delivery. There are two ways to do this. During an external version, the doctor moves your baby by pressing on the outside of your belly. During an internal version, the doctor inserts his hand through your vagina and cervix and moves the baby from the inside. If your doctor cant manually reposition your baby, a cesarean section may be needed.</p>

<strong>Other presentations</strong><p>If your baby is in a posterior position, his face is turned up toward your belly. This can make labor longer and more difficult, since the widest part of his head has to fit through the birth canal. You may be able to help your baby rotate into a normal, face-down position by getting on all fours with your bottom in the air, which allows your uterus to drop forward. Your doctor may also try to reposition your baby by reaching in through your vagina and gently rotating his head with his hand or forceps. If none of these methods works, a cesarean section may be needed.</p>

<strong>Other presentations, Part 2</strong><p>If your baby is transverse, he is lying horizontally in your uterus. Your doctor may try to manually turn him into a head-down position, but a cesarean section is usually needed.</p>
