【摘要】 目的:探讨足月妊娠孕妇采用双球囊导管促宫颈成熟的临床效果及其对母婴结局的影响。方法:将本院住院分娩的初产妇494例分为三组,以双球囊导管和控释地诺前列酮栓联合使用促宫颈成熟的产妇91例设为观察1组,以单纯控释地诺前列酮栓促宫颈成熟的产妇89例设为观察2组,以自然临产且阴道分娩的产妇314例设为对照组。比较三组的临床疗效。结果:观察1组促宫颈成熟总有效率为94.5%,显著高于观察2组65.2%,差异有统计学意义(P<0.05);观察1组阴道分娩率明显高于观察2组(P<0.05);三组总产程对比,观察1组最短、对照组最长(P<0.05);球囊和/或栓剂取出后,观察1组宫颈Bishop评分明显优于观察2组(P<0.05)。结论:双球囊导管应用于足月妊娠促宫颈成熟效果显著,可有效促宫颈成熟、缩短产程,且安全性较高,值得临床推广应用。

【Abstract】 Objective:To discuss the effect of double-balloon catheter on cervical ripening in full-term pregnancy and its influence of the maternal-infant outcomes.Method:494 primipara in our hospital were divided into three groups,the observation group 1 with 91 primipara was given double-balloon catheter and controlled-release Dinoprostone Suppositories on cervical ripening,the observation group 2 with 89 primipara was just given controlled-release Dinoprostone Suppositories on cervical ripening,the control group with 314 primipara was given spontaneous labor and vaginal delivery.The clinical effect among three groups were compared.Result:The total effective rate of cervical ripening in observation group 1 was 94.5%,higher than those of the observation group 2 of 65.2%,the was statistical significance(P<0.05);the vaginal delivery rate of the observation group 1 was significantly higher than those of the group 2(P<0.05);the total stage of labor time,the observation group 1 was the shortest and the control group was the longest(P<0.05).The cervical Bishop score after removal of balloon or (and) suppository,the observation group 1 was significantly better than the observation group 2(P<0.05).Conclusion:Double-balloon catheter on cervical ripening in full-term pregnancy has a significant effect on cervical ripening,which can effectively improve cervical ripening,shorten total stage of labor time,has good safety,which is worthy of clinical application.

據相关数据统计,我国剖宫产率46.2%,为亚洲国家中排名第一位,因此如何提高阴道自然分娩率尤为重要。近年来随着妊娠合并症发生率的增高,越来越多的产妇需要通过引产终止妊娠。足月妊娠引产是最常见的产科干预手段之一,在促进自然分娩中具有重要意义[1]。主要是通过各种手段发动产程,使胎儿及早脱离宫内环境,避免不良结局的发生。足月妊娠引产的成功与否取决于宫颈成熟度,若Bishop评分<6分则需促进宫颈成熟以提高引产率。目前,临床上对于促宫颈成熟及引产主要采用药物方式,包括缩宫素、地诺前列酮栓等,但效果仍欠满意[2]。而且若促成熟方法使用不当,反而会增加宫内窘迫发生率,提高剖宫产率。双球囊导管法是一种促宫颈成熟的新技术,近年来越来越广泛地应用于足月妊娠促宫颈成熟中。本研究通过回顾性分析494例初产妇的临床资料,探讨双球囊导管应用于足月妊娠促宫颈成熟及引产的效果,旨在对其临床应用提供科学依据,现报道如下。endprint
