Effect of amniotic fluid index after preterm premature rupture of membrane on pregnancy outcome and neonatal outcome

Objective To investigate the effect of amniotic fluid index after preterm premature rupture of membrane (PPRM) on pregnancy outcome and neonatal outcome. Methods 120 PPRM pregnant women treated at our hospital from April, 2015 to August, 2016 were selected as study objects and were divided into a control group (normal amniotic fluid) and an observation group (amniotic fluid volume abnormality) according to the amount of amniotic fluid, 60 cases for each group. The delivery method, perinatal complications, and neonatal situation were compared between these two groups. Results There was no statistical difference in vaginal accouche rate between these two groups (P>0.05). The cesarean section rate was 65.00% in the observation group and 25.00% in the control group. The normal vaginal delivery rate was 23.33% in the observation group and 60.00% in the control group. The incidences of umbilical cord prolapse, puerperal infection, and chorioamnionitis were significantly higher in the observation group than in the control group, with statistical differences (all P<0.05). The neonatal mortality rate was 18.33%, the intrauterine infection rate was 15.00%, the rate of meconium stained amniotic fluid was 13.33%, and the neonatal asphyxia rate was 16.67% in the observation group and which were 5.00%, 1.67%, 1.67%, and 3.33% in the control group, with statistical differences (all P<0.05). Conclusions After preterm premature rupture of membrane, too much and too little amniotic fluid both can increase the cesarean section rate and the risk of maternal complications and neonatal adverse circumstances, so amniotic fluid index after premature rupture can be used as an important index to observe the maternal and infant conditons.
