Cesarean delivery is indicated at any stage in the labor process in the presence of nonreassuring fetal status or when conservative measures fail in the setting of abnormal labor. In the absence of maternal or fetal indications for expedited delivery, cesarean delivery is not indicated for latent phase disorders. When to intervene for protracted labor is arguable, but slow rates of labor progress are consistent with safe vaginal delivery. Cesarean delivery in the second stage should be avoided for at least 4 hours if there is progressive fetal descent.
在分娩过程中的任何阶段,若出现胎儿状况不佳,或在产程异常时保守措施失败,均需行剖宫产。在没有产妇或胎儿需要紧急分娩的指征时,潜伏期异常无需行剖宫产。对于产程延长何时进行干预存在争议,但产程进展缓慢与安全的阴道分娩是相符的。如果胎儿有进行性下降,第二产程应至少避免剖宫产4小时。
