Previous randomized controlled studies in several different settings demonstrated the positive effects of continuous labor support by an experienced woman (doula) for low-income women laboring without the support of family members. The objective of this randomized controlled trial was to examine the perinatal effects of doula support for nulliparous middle-income women accompanied by a male partner during labor and delivery.
Nulliparous women in the third trimester of an uncomplicated pregnancy were enrolled at childbirth education classes in Cleveland, Ohio, from 1988 through 1992. Of the 686 prenatal women recruited, 420 met enrollment criteria and completed the intervention. For the 224 women randomly assigned to the experimental group, a doula arrived shortly after hospital admission and remained throughout labor and delivery. Doula support included close physical proximity, touch, and eye contact with the laboring woman, and teaching, reassurance, and encouragement of the woman and her male partner.
The doula group had a significantly lower cesarean delivery rate than the control group (13.4% vs 25.0%, p = 0.002), and fewer women in the doula group received epidural analgesia (64.7% vs 76.0%, p = 0.008). Among women with induced labor, those supported by a doula had a lower rate of cesarean delivery than those in the control group (12.5% vs 58.8%, p = 0.007). On questionnaires the day after delivery, 100 percent of couples with doula support rated their experience with the doula positively.
For middle-class women laboring with the support of their male partner, the continuous presence of a doula during labor significantly decreased the likelihood of cesarean delivery and reduced the need for epidural analgesia. Women and their male partners were unequivocal in their positive opinions about laboring with the support of a doula.
此前在几种不同情况下开展的随机对照研究表明,由经验丰富的女性(导乐)提供持续的分娩支持,对那些在分娩时没有家人陪伴的低收入女性具有积极影响。这项随机对照试验的目的是研究导乐支持对分娩期间有男性伴侣陪伴的初产中等收入女性围产期的影响。
1988年至1992年期间,在俄亥俄州克利夫兰的分娩教育课程中招募了妊娠晚期无并发症的初产妇。在招募的686名产前女性中,420名符合入选标准并完成了干预。对于随机分配到实验组的224名女性,导乐在她们入院后不久就到达,并在整个分娩过程中一直陪伴。导乐支持包括与产妇保持密切的身体距离、接触和眼神交流,以及对产妇及其男性伴侣进行教导、安慰和鼓励。
导乐组的剖宫产率显著低于对照组(13.4%对25.0%,p = 0.002),导乐组接受硬膜外镇痛的女性也更少(64.7%对76.0%,p = 0.008)。在引产的女性中,有导乐支持的女性剖宫产率低于对照组(12.5%对58.8%,p = 0.007)。在产后第二天的问卷调查中,100%接受导乐支持的夫妇对导乐的体验给予了积极评价。
对于在男性伴侣陪伴下分娩的中产阶级女性,分娩期间导乐的持续陪伴显著降低了剖宫产的可能性,并减少了硬膜外镇痛的需求。女性及其男性伴侣对在导乐支持下分娩的积极看法是明确无疑的。
