To evaluate the effect of continuous support provided by midwives during labor on the duration of the different stages of labor and the rate of cesarean delivery.
A randomized trial of 100 eligible nulliparous women who had not received education classes on childbirth. In the intervention group (n=50), continuous support during labor was provided; the control group (n=50) did not receive continuous support.
The two groups did not differ by age, employment, educational level, gestational age, economic status, and neonatal weight. Mean duration of the active phase of labor (167.9+/-76.3 vs 247.7+/-101 min, P<0.001), second stage of labor (34.9+/-25.4 vs 55.3+/-33.7 min, P=0.003), and the number of cesarean deliveries (4 vs 12, P=0.026) were significantly lower in the intervention group compared with the control group. The rates of oxytocin use and Apgar scores of less than 7 at 5 minutes were similar between the two groups.
Continuous support provided by midwives during labor may reduce the duration of labor and the number of cesarean deliveries; this model of support should be available to all women.
评估助产士在分娩过程中持续提供支持对分娩各阶段持续时间和剖宫产率的影响。
对 100 名符合条件的未接受分娩教育课程的初产妇进行随机试验。干预组（n=50）在分娩过程中持续接受支持；对照组（n=50）未接受持续支持。
两组在年龄、就业、教育水平、胎龄、经济状况和新生儿体重方面无差异。干预组活跃期（167.9+/-76.3 比 247.7+/-101 分钟，P<0.001）、第二产程（34.9+/-25.4 比 55.3+/-33.7 分钟，P=0.003）和剖宫产率（4 比 12，P=0.026）明显低于对照组。两组催产素使用率和 5 分钟时 Apgar 评分低于 7 分的比例相似。
助产士在分娩过程中持续提供支持可能会缩短产程和剖宫产率；这种支持模式应提供给所有女性。
