Immersion in water during labor or delivery has been popularized over the past several decades. The prevalence of this practice in the United States is uncertain because it has not been studied in births outside of the home and birth centers, and the data are not recorded on birth certificates. Among randomized controlled trials included in a 2009 Cochrane systematic review that addressed immersion in the first stage of labor, results were inconsistent with regard to maternal benefits. Neither the Cochrane systematic review nor any individual trials included in that review reported any benefit to the newborn from maternal immersion during labor or delivery. Immersion in water during the first stage of labor may be associated with shorter labor and decreased use of spinal and epidural analgesia and may be offered to healthy women with uncomplicated pregnancies between 37 0/7 weeks and 41 6/7 weeks of gestation. There are insufficient data on which to draw conclusions regarding the relative benefits and risks of immersion in water during the second stage of labor and delivery. Therefore, until such data are available, it is the recommendation of the American College of Obstetricians and Gynecologists that birth occur on land, not in water. A woman who requests to give birth while submerged in water should be informed that the maternal and perinatal benefits and risks of this choice have not been studied sufficiently to either support or discourage her request. Facilities that plan to offer immersion during labor and delivery need to establish rigorous protocols for candidate selection; maintenance and cleaning of tubs and pools; infection control procedures, including standard precautions and personal protective equipment for health care personnel; monitoring of women and fetuses at appropriate intervals while immersed; and moving women from tubs if urgent maternal or fetal concerns or complications develop.
在过去几十年里,分娩期间浸泡在水中的做法逐渐流行起来。在美国,这种做法的普及程度尚不确定,因为尚未在家庭和分娩中心以外的分娩中进行研究,且出生证明上也没有记录相关数据。在2009年Cochrane系统评价纳入的关于分娩第一阶段水中浸泡的随机对照试验中,关于对母亲的益处,结果并不一致。该Cochrane系统评价及其纳入的任何单项试验均未报告分娩期间母亲水中浸泡对新生儿有任何益处。分娩第一阶段水中浸泡可能与产程缩短、脊髓和硬膜外镇痛的使用减少有关,可提供给妊娠37 0/7周至41 6/7周、健康且无并发症的孕妇。关于分娩第二阶段水中浸泡的相对益处和风险,尚无足够数据得出结论。因此,在获得此类数据之前,美国妇产科医师学会建议在陆地上分娩,而非在水中。应告知要求在水中分娩的女性,这种选择对母亲和围产儿的益处及风险尚未得到充分研究,无法支持或劝阻她的请求。计划在分娩期间提供水中浸泡服务的机构需要制定严格的方案,包括候选人筛选;浴盆和水池的维护与清洁;感染控制程序,包括医护人员的标准预防措施和个人防护装备;浸泡期间定期对产妇和胎儿进行监测;以及在出现紧急的母亲或胎儿问题或并发症时将产妇从浴盆中移出。
