To assess the factors associated with failed induction of labour (IOL) in a secondary care hospital.
This is a retrospective cross sectional study on women admitted for labour induction in Aga Khan Hospital for women Karimabad from 1st Jan, 2009 to 31st Dec, 2009. Induction was considered successful if the patient delivered vaginally and failed if it ended up in Caesarean Section.
Eighteen percent of our pregnant population who underwent induction of labour failed to deliver vaginally. About 25% of 328 nulliparous women had failed induction. With a Bishop score of <5 in 84.3%. In 28.2% with prolonged latent phase of more than 20 hours in Caesarean section had to be performed.
Nulliparity, poor Bishop score and prolonged latent phase had strongest association with failed Induction of Labour. Macrosomia, gestation age, bad obstetric history and pre labour rupture of membranes were other significant risk factors for emergency caesarean sections in IOL.
评估二级护理医院中引产失败的相关因素。
这是一项回顾性横断面研究，研究对象为2009年1月1日至2009年12月31日在阿迦汗妇女医院卡里马巴德院区入院引产的女性。如果患者经阴道分娩，则引产被视为成功；如果最终进行剖宫产，则引产失败。
接受引产的孕妇中有18%未能经阴道分娩。328名初产妇中约25%引产失败。84.3%的产妇 Bishop 评分<5。28.2%潜伏期延长超过20小时的产妇不得不进行剖宫产。
初产、Bishop评分低和潜伏期延长与引产失败的关联最为密切。巨大儿、孕周、不良产科史和临产前胎膜早破是引产时紧急剖宫产的其他重要危险因素。
