Residue amniotic fluid volume after premature rupture of membranes and maternal-fetal outcome

Objective To determine the relationship between the residue amniotic fluid volume after premature rupture of membranes(PROM) and maternal-fetal prognosis.Methods 162 pregnant women with PROM were studied,hospitalized in department of Obstetrics and Gynecology,the Affiliated Hefei Hospital of Anhui Medical University from Jun.2011 to Dec.2011.According to Amniotic fluid index(AFl) by ultrasound,patients were assigned into three groups:(1) Group of normal amniotic fluid: 90 pregnant women(80 mm≤AFI 180 mm);(2) Group of borderline oligohydramnios: 40 pregnant women(50 mm≤AFI 80 mm)(3) Group of oligohydramnios: 32 pregnant women(AFI 50 mm).The final delivery style and the maternal and children stermination were compared.Results The dystocia rate of oligohydramnios group was significantly higher than that of normal amniotic fluid group(P 0.05).There was no significant difference between borderline oligohydramnios group and normal amniotic fluid group(P 0.05).The rupture distance delivery time of three groups had no significant difference(P 0.05).The puerperal morbidity of three groups had no significant difference(P 0.05).The Neonatal asphyxia of oligohydramnios group was significantly higher than that of normal amniotic fluid group(P 0.05).There was no significant difference between borderline oligohydramnios group and normal amniotic fluid group(P 0.05).There was no significant difference between borderline oligohydramnios group and oligohydramnios group(P 0.05).Conclusion Oligohydramnios after prom increase neonatal asphyxia and cesarean section rate.The amniotie fluid volume might be an important prognostic indicator to assess the maternal and neonatal outcomes when PROM happened.
