COOK球囊用于宫颈评分不同的足月妊娠引产的疗效观察

Clinical efficacy of COOK cervical ripening balloon on induced labour of term pregnancy with different cervical bishop scores

目的 探讨COOK球囊用于宫颈成熟度Bishop评分不同的初产妇、经产妇的临床疗效.方法 选择270例有引产指征的足月妊娠孕妇作为研究对象,宫颈成熟度Bishop评分1～2分的初产妇70例作为对照组1,宫颈成熟度Bishop评分3～5分的初产妇80例作为观察组1;宫颈成熟度Bishop评分1～2分的经产妇50例作为对照组2,宫颈成熟度Bishop评分3～5分的经产妇70例作为观察组2;比较观察组与对照组促宫颈成熟效果、球囊放置到分娩时长、总产程、分娩方式、产后出血量及新生儿情况.结果 观察组1促宫颈成熟总有效率、剖宫产率、产后出血、新生儿评分与对照组1比较,差异未见统计学意义（P＞0.05）;观察组1球囊放置到分娩时长、总产程与对照组1比较,差异有统计学意义（P＜0.05）;观察组2促宫颈成熟总有效率、剖宫产率、球囊放置到分娩时长、总产程、产后出血、新生儿评分与对照组2比较,差异未见统计学意义（P＞0.05）.结论 经产妇及宫颈成熟度Bishop评分3～5分的初产妇采用COOK球囊引产可有效促进宫颈成熟,COOK球囊可作为引产首选;宫颈成熟度Bishop评分1～2分的初产妇可根据其意见采用不同方法进行引产.

Objective To investigate the clinical efficacy of COOK cervical ripening balloon on primiparas and multiparas with different cervical Bishop scores.Methods A total of 270 full-term pregnancy women with induced labour indications were assigned as the research objects.Among them,80 primiparas with a cervical Bishop score of 3 to 5 points were selected as observation group 1,70 primiparas with a cervical Bishop score of 1 to 2 points were selected as control group 1;70 multiparas with a cervical Bishop score of 3 to 5 points were selected as observation group 2,50 multiparas with a cervical Bishop score of 1 to 2 points were selected as into control group 2.The promoting effect for cervical ripening effect,time of balloon placed to delivery,total labour time,mode of delivery,postpartum hemorrhage and neonatal status were observed and compared between observation groups and control groups.Results There was no significant difference in the promoting effect for cervical ripening,cesarean section rate,the volume of postpartum hemorrhage and neonatal status between control group 1 and observation group 1 （P 〉 0.05）,while there were significant differences in time of balloon placed to delivery and total labor time between control group 1 and observation group 1 （P 〈 O.05）.There was no significant difference in the promoting effect for cervical ripening effect,cesarean section rate,time of balloon placed to delivery,total labour time,the volume of postpartum hemorrhage and neonatal score between observation group 2 and control group 2 （P 〉 0.05）.Conclusions The COOK balloon can effectively improve cervical ripening in indution of term-pregnancy primiparas with a Bishop score of 3 to 5 points and multiparas,and COOK balloon can be the first choice;primiparas with a Bishop score of 1 to 2 points can choose different methods for induction.
