Induction of labor is a widely used practice. From 2016 to 2019, >1 in 3 women giving birth in the United States did so after undergoing labor induction. The obvious goal of labor induction is vaginal birth with minimal maternal or neonatal morbidity. To achieve this goal, criteria for failed labor induction are needed. Herein, we provide an evidence-based approach to safely prevent unnecessary cesarean deliveries for failed induction. Although there are no randomized trials comparing failed labor induction criteria, the observational data have been consistent: if the status of the mother and the fetus permits, at least 12 to 18 hours of oxytocin should be administered after membrane rupture before deeming an induction of labor to have failed because of nonprogression to the active phase of labor.
引产是一种广泛应用的做法。在美国，2016 年至 2019 年期间，超过三分之一的分娩女性都接受了引产。引产的明显目标是实现阴道分娩，并使母婴发病率最小化。为了实现这一目标，需要制定引产失败的标准。在此，我们提供一种循证方法，以安全地避免因引产失败而进行不必要的剖宫产。尽管没有比较引产失败标准的随机试验，但观察数据一直是一致的：如果母亲和胎儿的状况允许，在膜破裂后至少应给予 12 至 18 小时的催产素，然后再判定引产因未进展至活跃期而失败。
