胎膜早破与难产相关关系的研究

目的分析胎膜早破与难产的关系。方法316例胎膜早破孕妇为观察组(早破组),随机抽取同期300例无胎膜早破试产孕妇为对照组,从胎方位、分娩方式、新生儿Apgar评分、有无感染四个方面进行分析比较,采用χ2检验进行统计学处理。结果胎膜早破发生率与异常胎位呈显著性关系(P<0.01),早破组自然分娩率比对照组显著降低(P<0.01),而阴道手术产及剖宫产率则明显升高(P<0.01),新生儿窒息在两组间无明显差异(P>0.05),316例胎膜早破孕妇临床均无感染发生。结论胎膜早破与难产关系密切,胎位异常(尤其是头位的胎位异常)和阴道手术产及剖宫产率均显著增高。

Clinical analysis on the relationship of premature rupture of membranes and dystocia

Objective To study the relationship between premature rupture of membrane(PROM) and dystocia. Methods Authors took 316 cases of PROM as obversed group and 300 cases of non-PROM as control group and compared their fetal position,delivery methods,newborn Apgar score,infection,etc,then made the relative statistic analysis. Results The observed group showed higher rate of abnormal fetal position(P<0.01) and lower rate of normal labor than the control group. The rate of assisted delivery and caesarean section of the observed group was correspondingly rising(P<0.01). PROM had no correlation with newborn asphyxia(P>0.05). No infection happened in 316 cases of PROM. Conclusion PROM is related with dystocia closely. In PROM the rate of abnormal fetal position (especially head abnormal fetal position),assisted delivery and caesarean section remarkably increase.
