Abstract AIM: To determine whether an antepartum low amniotic fluid index (AFI) is a predictor of adverse perinatal outcome in normal pregnancy and to determine a threshold level of AFI that could predict an adverse outcome. METHODS: This was a prospective study conducted among 180 pregnant women at 37-40 weeks of gestation with no known obstetric or medical complications with an AFI ≤ 5th percentile. The results were statistically analyzed and compared. RESULTS: In the control group, the mean AFI was 10.14 cm and in the study group, it was 4.14 cm. 65 \% patients in the study group and 24 \% in the control group had a non-reactive non-stress Test. In the control group, 53 \% of patients were induced for reasons other than oligohydramnios, while in the study group, 86 \% of patients were induced for oligohydramnios. Among the control group, 33 \% had a LSCS, while 67 \% delivered vaginally; and in the study group, 34 \% delivered vaginally and 66 \% had a LSCS. In our study, a 5-min APGAR < 7 was seen in 34 \% in the study group and 11 \% in the control group. 33 \% neonates in the control group and 64 \% in the study group had birth weights <2.5 kg. CONCLUSIONS: In the presence of oligohydramnios, perinatal morbidity and mortality are high. Determination of AFI is a valuable screening test for predicting fetal distress.
