Cook宫颈扩张球囊用于妊娠晚期促宫颈成熟的临床研究

Application of Cook cervical expansion balloon in promoting cervical ripening at third trimester of pregnancy

目的探讨Cook宫颈扩张球囊应用于妊娠晚期促宫颈成熟的有效性及安全性。方法以2010年8月-2011年8月我院住院有引产指征且宫颈评分<4分的妊娠晚期初产妇为研究对象,42例自愿选择应用宫颈扩张球囊患者为研究组,同期58例选择应用催产素者为对照组,比较两组方法促宫颈成熟的效果、引产成功率及感染风险。结果研究组促宫颈成熟效果、引产成功率显著高于对照组(97.6%vs 36.2%,73.8%vs 37.9%,P<0.01),但体温、白细胞水平与对照组比较差异无统计学意义(P>0.05)。结论 Cook宫颈扩张球囊能有效扩张宫颈和促进条件不佳的宫颈成熟,不增加分娩过程中的感染几率。

Objective To study the efficiency and safety of Cook cervical expansion balloon in promoting cervical ripening at third trimester of pregnancy.Methods One hundred primiparae at third trimester of pregnancy with labor induction indications and their cervical score 〈 4,admitted to our hospital from August 2009 to August 2010,were enrolled in this study and divided into study group（n=42） and control group（n=58）.Primiparae in study group selected Cook cervical expansion balloon for induction of labor while those in control group selected oxytocin for induction of labor.Cervical ripening,labor induction and infection risk of the two methods were compared between the two groups.Results The cervical ripening efficiency and success induction rate of labor were significantly higher in study group than in control group（97.6% vs 36.2%,73.8% vs 37.9%,P〈0.01）.However,no significant difference was found in temperature and WBC between the two group（P〉0.05）.Conclusion Cook cervical expansion balloon can effectively expand the uterine neck,promote the cervical ripening in poor condition and does not increase the infection rate during delivery.
