Total cesarean section rates and rates of various indications for primary cesarean section were reviewed for four yearly periods during the past decade. The time periods studied were chosen to follow the introduction of new obstetric practices and technologic advances in monitoring fetal condition. The total cesarean section rate increased from 6.8% to 17.1% during this time. The most common indication for primary cesarean section was cephalopelvic disproportion, which represented approximately 40% of cases during each study period. Primary cesarean section for fetal distress increased to 28.2% but has decreased over the past 2 years to a present rate of 11.7%. Primary cesarean section for breech presentation increased from 12.3% to 21%. From the perspective of this review a total cesarean section rate of 15% is predicted for the future.
回顾了过去十年中四个年度期间的剖宫产总率以及初次剖宫产各种指征的发生率。所研究的时间段是为了跟踪新的产科实践和监测胎儿状况的技术进步而选定的。在此期间，剖宫产总率从6.8%上升至17.1%。初次剖宫产最常见的指征是头盆不称，在每个研究期间约占病例的40%。因胎儿窘迫进行的初次剖宫产率升至28.2%，但在过去两年中已降至目前的11.7%。臀位分娩的初次剖宫产率从12.3%升至21%。从本次综述来看，预计未来剖宫产总率将为15%。
