Abstract: Introduction:The ultimate goal of antepartum surveillance program is to improve perinatal outcome and to decrease intrauterine fetal demise besides prevention of maternal morbidity and mortality.Normal amniotic fluid index is one of the indicators of foetal well-being.Oligohydramnios is defined as amniotic fluid index (AFI) of less or equal to five centimetres.This study was conducted to determine whether an antepartum amniotic fluid index (AFI) of 5 cm or less can be used as an adjunct to other fetal surveillance methods as a predictor of adverse pregnancy as compared with outcome in those with normal AFI.Material and methods: This was a Cohort study done from over a period of 12 months (August 2016 to July 2017) at Civil Hospital, Aizawl.Patients were selected from those who fulfilled these inclusion and exclusion criteria.It consists of analysis of pregnancy outcome in 50 cases with diagnosis of oligohydramnios by ultrasound after 37 completed weeks of gestation (Cohort 1) compared with 50 controls with no oligohydramnios (Cohort 2) and matched for other variables like age, parity, gestational age.Various outcomes results were recorded and tabulated.The results were statistically analysed using parameters like mean, standard deviation and chi square test.In addition, epidemiological parameters like sensitivity, specificity, positive predictive value, negative value were used.Result: There were significant differences between two groups in delivery by LSCS for foetal distress (p-0.001)particularly among patients with AFI 0-1 (p-0.01).There was increased incidence of labour induction in women with AFI ≤ 5cms than women with AFI > 8 cms (p-0.01).Conclusion: An amniotic fluid index of ≤5 cms detected after 37 completed weeks of gestation is an indicator of poor pregnancy outcome.Determination of AFI can be used as an adjunct to other foetal surveillance methods.Determination of AFI is a valuable screening test for predicting foetal distress in labour requiring caesarean section.
