Breech Birth What is a breech position? Breech births occur in about 3% of term pregnancies. In the initial part of a pregnancy, the baby floats and turns every which way in the amniotic fluid. As the foetus grows, the intrauterine space begins to shrink and the baby has less and less space to float around in. Finally, around the 36th or 37th week, the baby settles down into a vertical, head-down position known as the vertex position. However, in the case of breech babies, they settle into a bottom-first or breech position. Up until 32 weeks gestation about 15% of babies lie this way, but the number at term is down to 3 or 4% as many spontaneously turn around without any assistance. There are three types of breech positions:
External Cephalic Version (ECV) A breech birth can be converted into a vertex position before the onset of labour by turning the baby manually. Manual manipulation of the breech baby is called external cephalic version (ECV). Some babies are stubborn and return to the breech position even after being turned. This is the reason doctors wait almost until term to turn the baby. ECV should not be attempted in the
following circumstances as it can lead to fetal distress or cause bleeding
or premature rupture of the membranes:
An ECV can be performed any time
after 36 weeks. The first step is to do an ultrasound scan to check the
position of the baby, the position of its limbs, the amount of amniotic
fluid, the location of the placenta, and the size of the baby and the mother.
All these factors have to be considered before taking the decision to go
ahead.
The procedure Once the doctor has given the go ahead, the woman is given some medication to relax her uterine muscles. The doctor then applies some body oil and places one of his hands on the mother's abdomen over the baby's head, the other over its buttocks. He then moves his hands in opposite directions as the baby is gently stroked around. The whole procedure takes a few minutes. The baby's heartbeat is monitored throughout the procedure to detect any sign of fetal distress like a significant increase, decrease or irregularity in the heart rate. In such a case, the baby is immediately returned to its original position. To ensure the success of ECV, the woman is usually requested to stay in an upright position for the rest of the day.
