METHODS
We describe a prospective study, done over a 2-year period in which a total of 958 women having a vaginal delivery were randomised to the drainage method (478 women) or controlled cord traction method (480 women) for placental delivery.
RESULTS
The mean age, parity, gestation and birth weight were similar in the two groups. The mean duration of third stage of labor was 3.24 min and 3.2 min in the placental drainage group in contrast to 8.57 min and 6.20 min in controlled cord traction method in primigravida and multigravida respectively.
CONCLUSION
Placental drainage significantly reduces the duration of third stage of labour in vaginal deliveries.
方法
我们描述了一项为期2年的前瞻性研究，共有958名经阴道分娩的妇女被随机分为胎盘娩出引流法组（478名妇女）或控制脐带牵引法组（480名妇女）以娩出胎盘。
结果
两组的平均年龄、产次、孕周和出生体重相似。初产妇和经产妇中，胎盘引流组第三产程的平均持续时间分别为3.24分钟和3.2分钟，而控制脐带牵引法组分别为8.57分钟和6.20分钟。
结论
胎盘引流显著缩短了阴道分娩第三产程的持续时间。
