The Correlation between Residual Amniotic Fluid Index after Premature Rupture of Membrane and Perinatal Infection Neonatal Morbidity

Objective:Our purpose was to determine whether the residual aminotic fluid index(AFI) of premature rupture of membrane(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 (P0.05),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 regress 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.
