An analysis of 931 consecutive inductions of labor over an eight-year period is presented. The success rate was 90.4%. Spontaneous vaginal delivery was achieved in 83.5% of cases and the induction-delivery interval was less than 12 hours in 82.6% of cases. The preinduction state of the cervix most significantly influenced the outcome of labor, followed by maternal age and parity. Provided induction of labor was by synchronous use of forewater amniotomy and oxytocin titration, labor outcome was regularly predictable two hours after induction using the concept of latent period of labor and the cervical dilatation at eight hours from the induction. When the latent period was two hours or less, 64.2% of the patients delivered within eight hours, and vaginal delivery was achieved in all women in whom the cervical dilatation was 8 cm or more at eight hours from the induction of labor. The maternal complication rate was 12.1%, the early neonatal morbidity was 11.6%, and the stillbirth rate was 2.3%.
本文呈现了对八年期间连续931例引产病例的分析。成功率为90.4%。83.5%的病例实现了自然阴道分娩，82.6%的病例引产至分娩间隔小于12小时。引产时宫颈的状态对分娩结局影响最为显著，其次是产妇年龄和产次。若引产采用同步人工破膜和缩宫素滴定法，运用产程潜伏期概念以及引产8小时时的宫颈扩张情况，引产两小时后分娩结局通常可预测。当潜伏期为两小时或更短时间时，64.2%的患者在8小时内分娩，且引产8小时时宫颈扩张8厘米或以上的所有女性均实现了阴道分娩。产妇并发症发生率为12.1%，早期新生儿发病率为11.6%，死产率为2.3%。
