目的:评价使用导尿管球囊行宫颈扩促宫颈成熟和引产的有效性及安全性。方法:选择有引产指征的足月妊娠产妇58例,宫颈评分≤4分,使用导尿管球囊宫颈扩张引产,取出球囊后视情况需要人工破膜或缩宫素静脉滴注。分析促宫颈成熟情况及引产效果、缩宫素应用后至临产时间、缩宫素应用时间、分娩方式、产程、分娩结局以及不良反应。结果:使用导尿管球囊12h后宫颈成熟率为91.07%,阴道分娩成功率83.9%;缩宫素使用总时间约5.5h(16.8%不需使用缩宫素)、总产程平均约11.28h,剖宫产率19.64%。结论:使用导尿管球囊宫颈扩张促宫颈成熟安全有效、简单易行、经济实惠,值得推广应用。
OBJECTIVE: To evaluate the effectiveness and safety of cervical catheterization and induction of labor using a catheter balloon. Methods: Select full-term pregnant women induction of labor indications 58 cases of pregnancy, cervical score ≤ 4 points, the use of catheter balloon dilatation induced abortion, removal of the balloon as the case requires artificial rupture of membranes or oxytocin intravenous infusion. Analysis of cervical ripening and induction of labor effects, oxytocin application to labor time, oxytocin application time, mode of delivery, labor process, delivery outcomes and adverse reactions. Results: The rate of cervical ripening was 91.07% and the vaginal delivery rate was 83.9% after using catheter balloon for 12h. The total time of using oxytocin was 5.5h (16.8% without oxytocin), and the average length of labor was about 11.28h , Cesarean section rate of 19.64%. Conclusions: It is safe and effective to use ureteric balloon to promote cervical ripening. It is simple and economical, which is worth popularizing and applying.
