BACKGROUND
Amniotomy or artificial rupture of membranes is routinely used for induction of labour.
AIMS
To assess the efficacy of amniotomy alone for induction.
METHODS
A retrospective descriptive study of 3,586 cases of amniotomy for induction of labour between July 1996 and December 1999.
RESULTS
In total, 26,670 women delivered in the National Maternity Hospital during the study period. Of these 4,928 women required induction of labour and 72.8% of these (n = 3,586) underwent amniotomy only for induction of labour. Spontaneous labour occurred in 90.1% of the women who underwent amniotomy within 24 h. Oxytocin as an induction agent was employed in 9.8% of cases. Overall, 80.5% of the women had a spontaneous delivery, 7.3% had a ventouse delivery, 4.3% had a forceps delivery, and 7.9% underwent a caesarean section. In total, 90.5% of multips and 63.4% of primips had a spontaneous vaginal delivery.
CONCLUSIONS
Amniotomy is a simple, safe and effective method of induction of labour.
背景
羊膜穿刺术或人工破膜术通常用于引产。
目的
评估单纯羊膜穿刺术引产的效果。
方法
对 1996 年 7 月至 1999 年 12 月期间 3586 例因引产而行羊膜穿刺术的病例进行回顾性描述性研究。
结果
在研究期间，共有 26670 名妇女在国立妇产医院分娩。其中 4928 名妇女需要引产，其中 72.8%（n=3586）仅行羊膜穿刺术引产。在 24 小时内进行羊膜穿刺术的妇女中，90.1%自发分娩。催产素作为引产剂应用于 9.8%的病例。总体而言，80.5%的妇女自然分娩，7.3%的妇女行产钳助产，4.3%的妇女行胎头吸引术，7.9%的妇女行剖宫产。共有 90.5%的多胎和 63.4%的初产妇自然阴道分娩。
结论
羊膜穿刺术是一种简单、安全、有效的引产方法。
