目的探讨早期人工破膜对子痫前期患者引产时产程的影响,以期为子痫前期患者适时终止妊娠确定恰当的引产方法。方法对160例中重度子痫前期患者分为A、B两组,A组采用缩宫素静脉滴注引产,待自然破膜,B组采用早期人工破膜加缩宫素静脉滴注引产。对两组患者的产程、剖宫产率及产后出血量进行比较。结果早期人工破膜组的潜伏期、活跃期及总产程时间明显缩短为(7.7±2.7)h,引产者均在破膜后24 h内结束分娩,剖宫产率明显下降为21%。结论早期人工破膜可有效缩短产程,减少母婴并发症及剖宫产率,是行之有效的引产方法。
Objective To investigate the effect of early artificial rupture of membranes on the labor process in preeclampsia in order to determine the appropriate induction of labor during the termination of pregnancy in patients with preeclampsia. Methods One hundred and sixty patients with moderate-severe preeclampsia were divided into A and B groups. A group received oxytocin intravenous drip induction, until spontaneous rupture of membranes, and group B received intravenous injection of artificial rupture of membrane and oxytocin intravenously. The two groups of patients with labor, cesarean section rate and postpartum hemorrhage were compared. Results The latent period, active period and total duration of labor were significantly shortened to (7.7 ± 2.7) h in the early rupture of the artificial rupture membrane. The induced labor rate was reduced to 21% within 24 h after rupture of membranes. Conclusion Early artificial rupture of the membrane can effectively shorten the labor process, reduce maternal and child complications and cesarean section rate, is an effective method of induction of labor.
