低位水囊促宫颈成熟在足月引产中的临床对比研究

A clinical comparative study of the method of low position water bag for full term pregnancy induced labor

目的：探讨低位水囊促宫颈成熟与催产素引产在足月引产中的优越性．方法：选择2009-01／2012-10妇产科病区宫颈评分小于6分，无催产素引产禁忌症晚孕孕妇，应用催产素引产成功者50例（对照组）；选择2012—12／2013-10足月孕妇希望结束妊娠、延期妊娠孕妇欲结束妊娠者、过期妊娠者，宫颈Bishop评分均小于6分，无水囊引产禁忌症者50例（研究组），观察指标为引产至宫口开大3cm时间、引产开始至分娩总时间．应用SPSS统计学软件分析两组的统计学差异，进行临床对比研究．观察指标：观察孕妇宫缩，引产至宫口开大3em时间，宫口开大3cm到分娩时间，引产至分娩总时间等．结果：①研究组应用水囊后至宫口开大3cm时间：（1545．5±486．3）min，对照组应用催产素引产至宫口开大3cm时间：（1749．5±512．4）min，差异有统计学意义（P〈0．01）；②研究组应用水囊至分娩时间：（1848．9±463．3）min，对照组应用催产素至分娩时间：（2014．6±519．8）min，差异有统计学意义（P〈0．01）．结论：宫颈不成熟是终止足月妊娠经阴道分娩的棘手问题，如何促官颈成熟，经过临床观察发现低位水囊促宫颈成熟进行足月引产是一种操作简便、行之有效、安全可靠、成功率高的最佳方法，明显降低剖宫产率，值得临床广泛推广．

AIM： To investigate advantages of low position water bag for full term pregnancy induced labor. METHODS： 100 cases were enrolled into this study. They were divided into two groups. 50 cases admitted into maternity ward from January 2009 to October 2012 were control group. They were induced with oxytocin without oxytocin induced labor contraindications, and their cervical score was less than six points. While 50 cases admitted into maternity ward from November 2012 to Octomber 2013 were study group. They were full term pregnancy, delayed pregnancy who want to end the pregnancy term and prolonged pregnancy without contraindication of induced of laber with water bag, and their cervical Bishop score was less than six points. The observed indicators were the time of inducing until the cervix was opened about 3 cm and the total time of inducing until delivering the baby. Analyzing the statistical differences by using SPSS statistical software in the two groups and making a clinical comparative study. RESULTS： The time of applying water bag until the cervix was opened about 3 cm were （ 1545.5 ± 486. 3） minutes in control group. The time of appiying oxytocin until the cervix was opened about 3 cm were （ 1749.5 ±512.4） minutes in study group. The difference was statistically significance （P 〈 0.01 ）. While the time of delivering with water bag were （ 1848.9 ± 463.3 ） minutes, and the time of delivering wth oxytocin were （2014.6 ± 519.8） minutes. The difference was statistically significant （P 〈 0.01 ）. CONCLUSION： Immature cervix is the termination of pregnancy. Clinical observation found that low position water bag for for term pregnancy induced labor is performed a simple, effective, safe, reliable and successful way. It effectively reduces the rate oi cesarean delivery and is worth of promoting.
