ABSTRACT

Objective: identify the efficacy of AFI (amniotic fluid index) in pregnant women as a predictor of pregnancy outcome including mode of delivery and neonatal outcome. Methods: a prospective cohort study done from September 2018 to February 2019, the study involved 300 women with a gestational age between (36 – 40 weeks). The AFI was measured by ultrasound (US), and accordingly, the women were divided into three groups: normal (AFI = 5 – 25cm), oligohydramnios (AFI <5cm), and polyhydramnios (AFI >25cm), each group consisting of 100 women. Results: The group of oligohydramnios has a significantly higher rate of C/S, induction of labor in comparison to normal and polyhydramnios (p-value <0.05). There’s a significant correlation between AFI and fetal weight, small for gestation is more in oligohydramnios and big baby in polyhydramnios. There’s a significant difference between AFI and clinical/visual intrapartum estimation amount of liquor. There is a significant association between CTG and 1st minute Apgar, but not significant with the 5th minute Apgar score. In true groups (AFI is same with visual estimation), there was a significant association between mode of delivery and neonatal outcome regarding admission to NICU, is higher in elective CS and emergency CS after failed induction of labor, the Failure rate of induction of labor due to fetal distress was more in true oligohydramnios group, but statistically not significant. Conclusions: Rate of induction of labor and C/S is higher in oligohydramnios comparing to polyhydramnios and normal liquor. In true oligohydramnios failed of induction due to fetal distress is more but statistically not significant. The type of delivery significantly affects neonatal outcomes regarding admission to NICU.
