Predicting the likelihood of successful vaginal birth after cesarean delivery.

摘要

The American College of Obstetricians and Gynecologists and the American Academy of Family Physicians recommend that pregnant women with a single previous cesarean delivery and a low-transverse incision be offered a trial of labor. Although the rate of vaginal birth after cesarean delivery (VBAC) increased from 19 percent of all deliveries in 1989 to a peak of 28 percent in 1996, the rate decreased to only 9.2 percent of all deliveries in 2004. The decline has been partially driven by concerns about the small but measurable risk of uterine rupture with VBAC, particularly when labor is induced or augmented.
