Vaginal Birth After Cesarean Delivery

摘要

Every year, approximately 1 in 3 babies in the United States is born via cesarean delivery. Although the major component of the rising cesarean rate relates to primary cesarean deliveries, the practice of repeat cesarean section has been a key focus of those who hope to curb the seemingly ever-rising rate. The doctrine of "once a cesarean, always a cesarean" has been increasingly questioned, and it was the de facto focus of a National Institutes of Health (N1H) Consensus Development Conference convened in 2010 to evaluate the current evidence on vaginal birth after cesarean delivery (VBAC). The conference developed a set of guidelines on VBAC, the goals of which are to help obstetricians more effectively select and care for patients who are considering a trial of labor after cesarean delivery (TOLAC).
