胎膜早破致早产的妊娠结局分析

Analysis on the pregnancy outcomes of premature delivery caused by premature rupture of fetal membranes

目的 探讨胎膜早破致早产发生的危险因素及对母儿的影响。方法 回顾性分析 116例胎膜早破致早产的原因及对母儿的影响 ,并对不同孕龄组 2 8～ 3 5周 3 5 + ～ 3 7周两组作分析比较。结果 77 6%胎膜早破致早产有易发因素存在。孕2 8～ 3 5周与孕 3 5 + ～ 3 7周间 ,胎膜早破致早产者分娩方式的比较 ,差异无显著性 (P >0 0 5 )。孕 2 8～ 3 5周胎膜早破致早产者新生儿发病率和死亡率明显高于孕 3 5 + ～ 3 7周者 (P <0 .0 1)。 2例新生儿死亡均发生在孕 3 0周前。结论 对于孕 2 8～3 5周胎膜早破致早产者宜采取期待疗法 ,以减少新生儿并发症的发生。对于孕周小者 ,尽量延长孕周至 3 0周以上 ,以降低新生儿死亡率。

ObjectiveTo investigate the risk factors of premature delivery caused by premature rupture of fetal membranes and its effect on the mother and the infant.[Methods]Retrospective analysis was made on 116 cases of premature delivery caused by premature rupture of fetal membranes to study the reasons and effect on the mother and infant. Analysis and comparison were made between the 28～35 weeks' pregnancy and the 35+～37 weeks' pregnancy.[Results]Easy happening factors exists in 77.6% of the cases. No significant difference was found in the mode of delivery. The neonate morbidity rate and mortality rate in the 28～35 weeks' group were significantly higher than that of the 35+～37 weeks' group (P<0.01). Both the two cases of neonatal death occurred before a gestational period of 30 weeks.[Conclusion]For the gestational age of 28～35 weeks' cases, waiting management scheme is suggested to be applied to decrease the neonatal complications. For the cases with PPROM, the gestational age should be prolonged to more than 30 weeks to decrease neonatal mortality.
