胎膜早破的时间与产科并发症

目的：研究胎膜早破（ＰＲＯＭ）的潜伏期与产科并发症的关系。方法：河南医科大学第三附属医院１９９１年１月～１９９２年１２月期间产科３００例ＰＲＯＭ病例的总结和分析。结果：随着潜伏期的延长，感染和难产的发生率上升（Ｐ＜０．００１和Ｐ＜０．０００）。潜伏期在１２ｈ以内者难产和感染的发生率与对照组无明显差异（Ｐ＞０．０５）。对ＰＲＯＭ采取促宫颈成熟、计划分娩等干预措施可有效地控制难产的发生，但潜伏期在６ｈ内干预组的难产发生率高于非干预组（Ｐ＜０．０５）。ＰＲＯＭ的产科并发症明显高于对照组（Ｐ＜０．０５）。结论：在ＰＲＯＭ的处理方面潜伏期是一个不容忽视的因素，１２ｈ以内尤其是６ｈ以内者不应视为绝对异常，但要警惕潜伏期过长带来的不良并发症并采取一系列有效的预防和治疗措施。

The Time of Premature Rupture of Membranes and the Obsterical Complication

Objective:To study the relationship between the time from rupture to labor (latent period) and the obstetrical complication of premature rupture of membranes (PROM).Methods Analyzing 300 cases of PROM of our hospital from Jan 1991 to Dec 1992.Results: The longer latent period,the higher the rate of infection or dystocia (P<0.001 or 0.000).But there is no obvious difference in the rate between the patients whose latent period is within 12 hours and the control group (P>0.05).In the group within 6 hours,the dystocia rate of intervented patients is higher than that of non intervented ones.Conclusion:In management of PROM,latent period is an important factor.The group within 12 hours,especially within 6 hours cant be absolutely regard abnormal.But the complication caused by delaying latent period should be paid attention to and some effective measures of prevention and treatment should be taken.
