摘要
目的探讨胎膜早破后残余羊水量与宫内感染和新生儿发病率的相关性。方法175例胎膜早破患者在破膜后均行超声检测羊水指数(AFI),根据残余AFI将孕妇分成3组羊水过少组(AFI≤50mm)22例、羊水量偏少组(50mm<AFI≤80mm)24例、羊水量正常组(AFI>80mm)129例,分析胎儿宫内感染、胎儿窘迫和新生儿发病等指标在3组之间的差别。结果羊水残余量少者,破膜时孕周和分娩孕周均明显比残余量多者短,胎儿宫内感染率和新生儿发病率明显增加。胎儿窘迫的发生与羊水残余量无明显相关性,孕妇的年龄、孕次、产次、破膜后继续妊娠的时间、分娩方式和胎儿的出生体重等在3组之间无明显差别。结论胎膜早破后,羊水残余量的减少可能与宫内感染和新生儿发病率升高等有关,可作为临床监测胎儿宫内安危的指标。
Objective：Our purpose was to determine whether the residual aminotic fluid index（AFI） of premature rupture of membrahe（PROM） is associated with an increased risk of perinatal infection and neonatal morbidity. Methods：175 Pregnant women with PROM were categorized into three groups according to the residual AFI;group of low - ,mid- and high- AFI （ n=22,24 and 129, respectively）. Perinatal outcomes were evaluated by intrauterine infection,fetal distress and neonatal morbidity. Results： Gestational ages at PROM,the duration between rupture of the membrane and delivery,and Gestational ages at delivery were significantly lower in low- AFI group than in high - AFI group （P〈0.05） ,while the different of maternal age,fetal birth weight,mode of delivery among these three groups were similar. The incidence of intrauterine infection and neonatal morbidity were increased from low - AFI group though mid, AFI group to high - AFI group; the difference proved to be significant using Logistic negress analysis. However,the association of fetal distress and residual AFI was not significant. Conclusions： A significantly decreased residual AFI after PROM was associated with an increased risk of intrauterine infection and neonatal morbidity, which could be used as a valuable monitoring index in clinical practice.
