The cesarean delivery rate in the United States has risen steadily over the past 5 decades such that approximately one in three women now undergo cesarean section. The rise in repeat operations and accompanying decline in trial of labor after cesarean (TOLAC) have been major contributors to this phenomenon. The appropriate use of TOLAC continues to be a topic of interest with the recognition that most women with a history of prior cesarean are candidates for trial of labor. The NICHD MFMU Network Cesarean Registry conducted from 1999 to 2002 provided contemporary data concerning the risks and benefits of TOLAC, which in turn have helped inform practitioners and women considering their options for childbirth following cesarean delivery.
在过去50年里,美国的剖宫产率稳步上升,如今约有三分之一的女性接受剖宫产。再次手术率的上升以及随之而来的剖宫产术后试产(TOLAC)率的下降是导致这一现象的主要因素。鉴于大多数有剖宫产史的女性都是试产的候选人,TOLAC的合理应用仍是一个备受关注的话题。1999年至2002年进行的美国国立儿童健康与人类发展研究所母胎医学单位网络剖宫产登记提供了有关TOLAC风险和益处的当代数据,这些数据反过来有助于为从业者和考虑剖宫产术后分娩选择的女性提供信息。
