We studied the effects of a supportive lay woman ("doula") on the length of labor and on mother-infant interaction after delivery in healthy Guatemalan primigravid women. Initial assignment of mothers to the experimental (doula) or control group was random, but controls showed a higher rate (P less than 0.001) of subsequent perinatal problems (e.g. cesarean section and meconium staining). It was necessary to admit 103 mothers to the control group and 33 to the experimental group to obtain 20 in each group with uncomplicated deliveries. In the final sample, the length of time from admission to delivery was shorter in the experimental group (8.8 vs. 19.3 hours, P less than 0.001). Mothers who had a doula present during labor were awake more after delivery (P less than 0.02) and stroked (P less than 0.001), smiled at (P less than 0.009), and talked to (P less than 0.002) their babies more than the control mothers. These observations suggest that there may be major perinatal benefits of constant human support during labor.
我们研究了一位有支持作用的非专业女性(“导乐”)对危地马拉健康初产妇分娩时长以及产后母婴互动的影响。母亲最初被随机分配到实验组(导乐组)或对照组,但对照组随后出现围产期问题(如剖宫产和胎粪污染)的发生率更高(P<0.001)。为了使每组有20例顺产的产妇,有必要让103位母亲进入对照组,33位进入实验组。在最终样本中,实验组从入院到分娩的时间更短(8.8小时对19.3小时,P<0.001)。分娩时有导乐陪伴的母亲产后清醒的时间更多(P<0.02),抚摸(P<0.001)、对婴儿微笑(P<0.009)以及与婴儿交谈(P<0.002)的次数都比对照组母亲多。这些观察结果表明,分娩期间持续的人力支持可能会给围产期带来重大益处。
