Management of breech presentation and delivery.

Vaginal delivery of a fetus in breech position carries a risk three times that of vertex delivery. Patients must be carefully selected for vaginal delivery. The position should be that of a frank breech; the child should not be excessive in size; the mother's pelvis should be normal, and there should be no other complications of pregnancy. The fetal heart rate should be carefully monitored throughout labor. When patients with breech position are carefully studied, about two-thirds will be delivered by cesarean section.
