Elective induction of labor is at an all-time high in the United States despite known associated risks. It can lead to birth of an infant too early, a long labor, exposure to a high-alert medication with its potential side effects, unnecessary cesarean birth, and maternal and neonatal morbidity. There is a cascade of interventions related to elective induction such as an intravenous line, continuous electronic fetal monitoring, confinement to bed, amniotomy, pharmacologic labor stimulating agents, parental pain medications, and regional anesthesia, each with their own set of potential complications and risk of iatrogenic harm. These risks apply to all women having the procedure, however for nulliparous women before 41 weeks of gestation with an unfavorable cervix, the main risk is cesarean birth after unsuccessful labor induction with the potential for maternal and neonatal morbidity and increased healthcare costs. When cesarean occurs, subsequent births are likely to be via cesarean as well. Elective labor induction before 41 weeks is inconsistent with quality perinatal care, and performance of this unnecessary procedure should be minimized. Convenience as the reason for labor induction is contrary to a culture focused on patient safety. A review of current evidence, followed by changes in practice, is warranted to support the safest care possible during labor and birth. Various strategies to reduce the rate of elective induction in the United States are presented.
在美国,尽管已知存在相关风险,但选择性引产的比例却达到了历史最高水平。它可能导致婴儿过早出生、产程延长、接触具有潜在副作用的高警示药物、不必要的剖宫产以及孕产妇和新生儿发病。与选择性引产相关的一系列干预措施包括静脉输液、持续电子胎心监护、卧床限制、人工破膜、药物引产剂、产妇止痛药物以及区域麻醉,每一项都有其自身的潜在并发症和医源性伤害风险。这些风险适用于所有接受该手术的女性,然而对于妊娠41周前宫颈条件不佳的初产妇来说,主要风险是引产失败后进行剖宫产,这可能导致孕产妇和新生儿发病以及医疗费用增加。当进行剖宫产时,后续分娩也很可能通过剖宫产进行。妊娠41周前的选择性引产不符合优质围产期护理的要求,应尽量减少这种不必要手术的实施。将引产作为便利手段的做法与以患者安全为重点的文化相悖。有必要对现有证据进行审查,并随之改变做法,以支持分娩期间尽可能安全的护理。本文介绍了美国降低选择性引产率的各种策略。
