Our objective was to identify risk factors for failed labour induction. From January 2001 to December 2005, we conducted a retrospective case-control study in a Nigerian University Hospital. Cases were women who failed to deliver vaginally after labour induction, and therefore had caesarean section. Controls were patients who were similarly induced and achieved vaginal delivery. Univariate followed by Logistic regression analysis were performed. Failed induction occurred in 37.6%. Variables significantly and independently associated with failed induction were cervical effacement < 70% (adjusted odds ratio [OR] 5.12; 95% confidence interval [CI] 2.65-9.90), Bishop's score < 6 (OR 3.47; CI 1.75 - 6.85), nulliparity (OR 3.91; CI 1.92 - 7.99). Prolonged pregnancy independently reduced failure rate (OR 0.44: CI 0.24 - 0.81). These variables can help determine patients that will require early recourse to caesarean delivery in order to avoid prolonged induction-delivery interval.
我们的目标是确定引产失败的风险因素。2001年1月至2005年12月，我们在一家尼日利亚大学医院进行了一项回顾性病例对照研究。病例为引产术后未能经阴道分娩、因此接受剖宫产的女性。对照为同样接受引产并成功经阴道分娩的患者。进行了单因素分析，随后进行逻辑回归分析。引产失败率为37.6%。与引产失败显著且独立相关的变量包括宫颈消退<70%（调整比值比[OR]5.12；95%置信区间[CI]2.65 - 9.90）、Bishop评分<6（OR 3.47；CI 1.75 - 6.85）、初产（OR 3.91；CI 1.92 - 7.99）。过期妊娠独立降低了失败率（OR 0.44：CI 0.24 - 0.81）。这些变量有助于确定哪些患者需要尽早采取剖宫产，以避免引产至分娩间隔延长。
