胎膜早破后羊水残余量与宫内感染和新生儿发病率的相关性分析

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：根据产妇胎膜早破后残余羊水指数（Amnitic Fluid Index，AFI）的监测结果，将本组120例产妇分为三组：羊水量正常组82例；羊水量较少组20例；羊水量过少组18例。所有产妇入院后行胎膜早破常规处理，回顾分析并统计三组产妇宫内感染率，胎儿窘迫率和新生儿发病率。结果：在宫内感染发生率上，三组比较，差异具有显著性，羊水量较少组、羊水量过少组宫内感染的发生率明显高于羊水量正常组（P〈0．01）。在胎儿窘迫发生率上，三组比较，差异无统计学意义（P〉0．05）。在新生儿发病率上，三组比较，差异具有显著性，羊水量较少组、羊水量过少组新生儿的发病率明显高于正常纽（P〈0．01）。Logistic回归分析发现羊水量、产妇基础性疾病和分娩孕周为孕产妇宫内感染和新生儿发病的关键影响因素。结论：胎膜早破后残余羊水量过少与宫内感染和新生儿发病=翠的升高密切相关，产妇于胎膜早破后应加强残余羊水量的监测，以采取有效措施降低宫内感染和新生儿发病的发生率。

Correlation Relationship between the Residual Amount of Amniotic Fluid after Premature Rupture of Fetal Membrane and Intrauterine Infection and the Incidence of Neonatal

Objective： To study the correlation relationship between the residual amount of anmiotic fluid after premature rupture of fetal membrane and intrauterine infection and the incidence of neonatal. Method： According to the monitoring results of Anmiotic Fluid Index （Amniotic Fluid Index, AFI） after premature rupture of membranes maternal of the residual, 120 cases of lying-in women were di- vided into three groups： normal group of amniotic fluid volume had 82 cases; amount less group of amniotic fluid volume had 20 cases; Too little amount group ofamniotic fluid volume had 18 cases, all maternal hospitalized were given the conventional treatment of prema- ture rupture of membranes, the rate of maternal intrauterine infection and fetal distress and neonatal morbidity in the three groups were retrospectively analyzed. Results： On the incidence of intrauterine infection, the difference from the three groups was significant; in- trauterine infection rate in amount less group of amniotic fluid volume, too little amount group of amniotic fluid volume were significant- ly higher than that in normal group （P〈0.01）. On the incidence of fetal distress, there was no statistically significant difference （P〉0.05）. On neonatal morbidity, there was significant difference among the three groups, the incidence of neonatal in amount less group of amni- otic fluid volume, too little amount group of amniotic fluid volume were significantly higher than that in normal group （P〈0.01）. Logistic regression analysis showed that anmiotic fluid,maternalbasic disease and gestational age were key factors of maternal intrauterine infec- tion and neonatal morbidity. Conclusion： The too little amount of amniotic fluid after premature rupture of fetal membrane is closely related to the increase of intrauterine infection and the incidence of neonatal, The residual amount should be strengthened for puerperal after premature rupture of fetal membranes, effective measures is adopt to reduce the incidence of intrauterine infection and neonatal morbidity.
