Breech describes the position of the baby just before or during delivery.
A few weeks before birth, most babies will reposition themselves so that their heads are pointed down towards the birth canal. This is the optimal position for birth. If this does not happen, the baby's buttocks or feet will be in place to be delivered first. This is called a breech presentation.
Breech positions occur in about 1 of 25 full-term births.
The causes of breech presentations are not fully known. However, a breech birth is more common :
A few weeks prior to the due date, the health care provider may place his/her hands on the mother's lower abdomen to locate the baby's head, back, and buttocks. If they think the baby is in a breech position, an ultrasound may be used to confirm. Special x-rays can also determine the baby's position and measure the pelvis to determine if a vaginal delivery of a breech baby may be attempted.
Most breech babies are born healthy. However, they do have a higher risk for certain problems than babies born head first. Birth defects are slightly more common in breech babies. A birth defect may be the reason they have not moved into the right position before birth.
The best time to try to turn a breech baby is between 32-37 weeks of pregnancy. There are many different types of methods to use and all have different levels of success. Talk with your health care provider about which options they feel would be best for you to try.
Most health care providers do not believe a vaginal delivery is possible for a breech birth, although some will wait to make that decision until a woman is in labor. However, the following are often necessary in order for a vaginal birth to be attempted:
In a breech birth, the baby's head is the last part to emerge, and it may be harder to ease it through the birth canal. Sometimes forceps are used to guide the baby's head out. Another potential problem is cord prolapse in which the umbilical cord can get squeezed as the baby moves toward the birth canal, slowing the baby's supply of oxygen and blood.
If a vaginal delivery is attempted, electronic fetal monitoring will be used to monitor the baby's heartbeat throughout labor. A cesarean delivery may be considered if there are any signs that the baby may be in distress.
Most health care providers recommend a cesarean delivery for all babies that are in a breech position, especially those that are premature. Premature babies are small and fragile, and because the head is relatively larger, their bodies don't stretch the cervix as wide as full-term babies do during birth. This means that there may be less room for the head to emerge.
