To determine whether sweeping of the membranes is an effective method of induction of labour in women with prolonged pregnancy.
Randomized controlled trial.
A district maternity hospital.
65 women attending an antenatal clinic; 33 randomized to sweeping of the membranes and 32 to a control group.
Proportion of women achieving spontaneous labour.
Spontaneous labour occurred more often in the sweeping of the membranes group than in the control group (25/33 (76%) vs 12/32 (38%); odds ratio (OR) 4.65; 95% confidence interval (CI) 1.75 to 12.31; P = 0.002). In addition a greater proportion of women in the sweeping group had a cervical dilatation of 4 cm or more at the first vaginal examination in the labour ward (16/33 (49%) vs 5/32 (16%); OR 4.39; 95% CI 1.56 to 12.32; P = 0.005). There were fewer maternal infections in the sweeping group (0/33 vs 4/32 (12%); OR 0.12; 95% CI 0.02 to 0.88; P = 0.04). There were no differences in the type of analgesia used in labour, the mode of delivery or neonatal outcome.

确定人工破膜是否是过期妊娠妇女引产的有效方法。
随机对照试验。
一家地区妇产医院。
65名参加产前门诊的妇女；33名随机分配至人工破膜组，32名分配至对照组。
自然分娩的妇女比例。
人工破膜组自然分娩的发生率高于对照组（25/33（76%）对12/32（38%）；优势比（OR）4.65；95%置信区间（CI）1.75至12.31；P = 0.002）。此外，人工破膜组中更大比例的妇女在产房首次阴道检查时宫颈扩张达4厘米或以上（16/33（49%）对5/32（16%）；OR 4.39；95%CI 1.56至12.32；P = 0.005）。人工破膜组产妇感染较少（0/33对4/32（12%）；OR 0.12；95%CI 0.02至0.88；P = 0.04）。分娩时使用的镇痛类型、分娩方式或新生儿结局无差异。
