adverse perinatal outcomes in borderline amniotic fluid index

Background: normal amniotic fluid predicts normal placental function, fetal growth and fetal well-being. objective: to determine adverse pregnancy outcomes in borderline amniotic fluid index (afi). materials and methods: pregnant women (37-40 wks) with diagnosis of borderline afi between december 2012 and august 2014 were identified. antepartum, intrapartum and neonatal data were collected and compared with those of pregnant women with normal afi. an afi less than 8 and more than 5 cm was defined for borderline afi. pregnancy outcomes included cesarean section for non-reassuring fetal heart rate, meconium stained amniotic fluid, 5-min apgar score <7, low birth weight, umbilical cord blood ph at term and nicu admission. results: gestational age at delivery in pregnancies with borderline afi was significantly lower than normal afi. cesarean section rate for non-reassuring fetal heart rate in women of borderline afi was significantly higher and there was an increased incidence of birth weight less than 10pthp percentile for gestation age in borderline afi group. incidence of low apgar score and low umbilical artery ph in pregnancies with borderline afi was significantly higher than women with normal afi. there were no significant difference in the rate of nicu admission and meconium staining in both groups. conclusion: there are significant differences for adverse pregnancy outcomes , such as cesarean section due to non-reassuring fetal heart rate, birth weight less than 10pthp percentile for gestation age, low 5 min apgar score and low umbilical artery ph between pregnancies with borderline and normal afi.
