[摘要] 目的 探討妊娠晚期引产术中应用宫颈扩张球囊的效果。方法 方便选择2016年1月—2018年1月期间在该院行晚期妊娠引产术的120例产妇，按照随机方法将其分为两组，每组60例。对照组患者采用人工破膜联合小剂量缩宫素引产，观察组患者采用宫颈扩张球囊促进宫颈成熟引产。观察并评价两组患者宫颈成熟度，记录两组患者第一产程和总产程时间。同时就两组患者分娩方式进行分析。结果 观察组和对照组引产总有效率分别为98.33%、91.67%，两组比较差异有统计学意义（χ2=4.669 0，P<0.05）。观察组患者第一产程（301.35±21.05）min、总产程（368.74±30.26）min，对照组患者第一产程（358.76±24.88）min、总产程（500.17±40.23）min，相较于对照组，观察组时间更短（t=6.890 6，8.107 3，P<0.05）。观察组患者阴道分娩率90.00%显著高于对照组78.33%，差异有统计学意义（χ2=5.109 3，P<0.05）。结论 在晚期妊娠引产术中应用宫颈扩张球囊可促进宫颈成熟，缩短患者产程，提高引产成功率，改善妊娠产妇母婴结局。

[Abstract] Objective To study the application effect of cervical expansion ballon in the induced labor in late pregnancy. Methods 120 cases of delivery women for late induced labor in our hospital from January 2016 to January 2018 were conveniently selected and randomly divided into two groups with 60 cases in each， the control group were treated with artificial rupture of membranes combined with small-dose oxytocin for induced labor， while the observation group were treated with cervical expansion ballon， and the cervical ripening degree of the two groups was observed and evaluated， and the first labor course and total labor time of the two groups were recorded， and the delivery way was analyzed. Results The total effective rate of induced labor in the observation group and in the control group was respectively 98.33%， 91.67%， and the difference was statistically significant （χ2=4.669 0， P<0.05） ， and the first labor course and total labor course in the observation group were shorter than those in the control group，[（301.35±21.05） min， （368.74±30.26） min vs （358.76±24.88） min，（500.17±40.23） min]（t=6.890 6，8.107 3，P<0.05）， and the vaginal delivery rate in the observation group was obviously higher than that in the control group，（90.00% vs 78.33%）， and the difference was statistically significant （χ2=5.109 3，P< 0.05）. Conclusion The application of cervical expansion ballon in the induced labor in late pregnancy can promote the cervical ripening， shorten the labor course， improve the induced labor successful rate and improve the maternal and infant outcomes of delivery women.

引产是产科常见的手术，因母亲和胎儿的原因，继续妊娠可能影响母婴生命，此时需要采用人工诱发子宫收缩而终止妊娠。对于妊娠晚期产妇来说，因宫颈条件不成熟，在终止妊娠时可能导致一系列的分娩并发症，危害母婴安全。因此，对于妊娠晚期的引产需要采用有效、安全的方式进行。宫颈扩张球囊的应用受到医生及患者的认可，其效果显著，安全性高[1]。该次研究以2016年1月—2018年1月期间在该院行晚期妊娠引产术的120例产妇为例，探讨妊娠晚期引产术中应用宫颈扩张球囊的效果，现报道如下。

1.1 一般资料

方便选取的120例产妇均为该院收治，所有产妇均行晚期妊娠引产术。随机将其分为观察组和对照组，每组60例。观察组60例产妇年龄在23～38岁，平均（30.54±6.23）岁，孕周在37～40周，平均（38.54±1.24）周。对照组60例产妇年龄在22～35岁，平均（31.22±5.78）岁，孕周在38～40周，平均（38.62±1.45）周。……
