目的探讨人工破膜时机对产程的影响。方法本文采用回顾性研究方法对2004年6月至2006年6月间我院住院经阴道分娩的258例初产妇,按活跃期人工破膜时机的不同分为三组,即加速,最大加速,减速阶段各一组(A组136例,B组63例,C组59例),分析比较各组产程时间的差异。结果三组活跃期分别为2.38±1.26h,2.67±1.56h,2.19±1.48h,总产程时间分别为9.38±2.68h、9.14±2.38h、7.29±2.46h。三组活跃期无显著性差异,越接近活跃期晚期行人工破膜,总产程越短。结论活跃期常规破膜对产程影响不大,无指征时尽量不行破膜,等待自然破膜。
Objective To investigate the timing of artificial rupture of membranes on the impact of labor. Methods In this retrospective study, 258 primiparae during vaginal delivery in our hospital from June 2004 to June 2006 were divided into three groups according to the timing of artificial rupture of membranes during the active phase: acceleration, maximal acceleration, Each group had a deceleration phase (136 cases in group A, 63 cases in group B and 59 cases in group C). The difference of labor hours in each group was analyzed and compared. Results The active periods of the three groups were 2.38 ± 1.26h, 2.67 ± 1.56h and 2.19 ± 1.48h respectively, and the total duration of labor was 9.38 ± 2.68h, 9.14 ± 2.38h and 7.29 ± 2.46h respectively. No significant difference between the three groups of active stage, the closer to the active phase of artificial rupture of the line, the shorter the total labor. Conclusion The active phase of rupture of membranes has little effect on the birth process, as far as possible without rupture of membranes, waiting for natural rupture of membranes.
