Abstract：Objective To analyze and discuss the impacts of the outcome of pregnancy according to the residual amount of amniotic fluid after full-term premature rupture of fetalmembranes. Methods 143 puerperas were divided into three groups according to their prenatal B ultrasound detection of residual amniotic fluid index(AFI) results, including Group A (8 cm≤AFI<25 cm) 75 cases,Group B(5 cm≤AFI<8 cm) 38 cases and Group C(AFI＜5 cm) 30 cases. Thedifferenceswere comparedbetween the three groups of pregnant women in mode of delivery, intrauterine infection, fetal distress, neonatal morbidity and meconium stained amniotic fluid rate. Results The cesarean section rate in Group C was significantly higher than in Group A (70.00% vs 37.30%,P＜0.05). The spontaneous vaginal delivery rates in Group C and Group B were lower than in Group A, with a significant difference(P＜0.05). The intrauterine infection rate, the incidence of neonatal disease, the meconium stained amniotic fluid rate and the incidence of fetal distress in Group C were higher than in Group A, with statistically significant difference(P＜0.05). The othercomparisonsbetween groups showed no significant difference. From the Logistic regression analysis results of the risk factors on maternal intrauterine infection rate and neonatal morbidity, it was known that the residual amount of amniotic fluid, the time of membranes ruptured till delivery and the meconium stained amniotic fluid were the main factors influencing the maternal intrauterine infection rate and neonatal morbidity. Conclusions The residual amount of amniotic fluid after full-term premature rupture of fetal membranes closely relates to the pregnancy outcome. The less the residual amount of amniotic fluid, the more seriousthe threat of maternal and infant health.
