Corre1ation between Rresidue amniotic fluid volume after preterm premature rupture of membranes and perinatal morbidity

Abstract

Objective To determine the relationship between the residue amniotic fluid volume after preterm premature rupture of membranes(PPROM) and perinatal morbidity. Methods Eightytwo pregnant woman women with PPROM during 28-36 gestational weeks were studied, hospitalized in Shaoguan maternal Maternal and child Child health Health Hospital from Dec.2004 to Dec.2009, and The fFirst People's hHospital of aShaoguan cCity from Dec,2004 to Dec,2009. All patients are were willing to take part in these experiments. According to Amniotic amniotic fluid index(AFI) by ultrasound, patients were devided into three groups: (1)① Group of oligohydramnis :AFI＜50 mm;(2) ② Group of borderline oligohydramnios: 50 mm ≤ AFI＜80 mm; ③(3) Group of normal amniotic fluid: 80mm ≤ AFI＜180mm.All the groups were similar with patient's' age. neonatal respiratory distress syndrome,neonatal hypoxic ischemic encephalopathy and neonatal respiratory failure ( P＞0.05 ). Results Group of oligohydramnios fetal distress (50%), neonatal asphyxia(50%), early-onset neonatal sepsis(53.8) and hypoxic-ischemic myocardial injury(48.0%) than those in Group group of normal amniotic fluid(8.3%, 16.7%, 15.3%, 12.0%;P＜0.05). Conclusions Oligohydramnios after pprom is associated fetal distress ,neonatal asphyxia,early-onset neonatal sepsis and hypoxic-ischemic myocardial injury.so, tThe amniotic fluid volume might be an important prognostic indicator to assess perinatal morbidity when PPROM happenedhappens. Key words: PPROM; Residue amniotic fluid volume volume; Perinatal perinatal morbidity
