胎膜早破对分娩方式的影响及产程观察

Effects of premature rupture of membranes on delivery mode and birth process

目的：探讨胎膜早破对产妇分娩方式及其产程的影响。方法选取2012年1月～2014年4月我院胎膜早破患者120例作为研究对象（观察组），选取同时期足月无胎膜早破正常产妇120例作为对照组，分析两组不同病情产妇对分娩方式、产程的影响。结果观察组阴道顺产率、剖宫产率分别为65.8％、34.2％，对照组则分别为78.3％、21.7％，观察组剖宫产率显著地高于对照组（x2=4.659，P=0.031）。观察组总产程时间、第二产程时间分别为（758.2±116.1）min、（92.6±12.8）min，均显著地高于对照组的（425.8±89.6）min、（38.4±4.1）min（t=24.829，P=0.000；t=44.174，P=0.000）。结论胎膜早破会提高剖宫产分娩率和延长产程时间，这可能与胎膜早破导致难产相关。

Objective To investigate effect of premature rupture of membranes on delivery mode and birth process. Methods 120 cases of patients with premature rupture of membranes from January 2012 to April 2014 in our hospital were selected as observation group, 120 cases of normal pregnant women were selected as control group. Effect of two groups on delivery mode and birth process were analyzed. Results The cesarean section rate of observation group was 34.2 % , which was significantly higher than that of control group （21.7 % ）（x2=4.659, P=0.031）. The vaginal delivery rate of observation group was 65.8%, which was significantly lower than that of the control group（78.3%）（x2=4.659, P=0.031）. The total labor time, and the second stage of labor time of observation group were（758.2±116.1）min, （92.6±12.8）min, which were significantly higher than those of the control group（425.8±89.6）min, （38.4±4.1）min （t=24.829, P=0.000; t=44.174, P=0.000）. Conclusion Premature rupture of membranes will increase the cesarean section rate and prolong the time of birth process, which was related with premature rupture of membranes resulting in dystocia.
