Background: Oligohydramnios is associated with a variety of ominous pregnancy outcomes such as foetal distress, low birth weight, perinatal morbidity and increased incidence of Caesarean section. Objective of present study was to determine the outcome of maternal and Foetal wellbeing after diagnosis of oligohydramnios at term pregnancy.

Methods: 50 pregnant women aged between 18 – 27 years were screened with history of oligohydramnios by ultrasound scanning after 37 completed weeks, compared with 50 controls with no oligohydramnios.

Results: The mean age of the study group was 22.7 years and of the control group was 22.4 years, respectively. Majority of the patients were primigravidae in both the groups. The mean gestational age was 39.5 weeks in study group and 39.4 in control group. The occurrence of non reactive NST was more in study group compared to the control group. The efficacy of AFI as a screening test to predict foetal distress is more significant with Positive Predictive Value of 57% and Negative Predictive Value of 80%. The mean birth weight was 2.5 kg in the study group compared to 2.75 kg in the control group which is statistically significant. 34 % of the newborns were admitted to NICU in study group compared to 14% in the control group.

Conclusions: In the presence of oligohydramnios, the occurrence of non-reactive NST, meconium stained liquor, development of foetal distress are very high.
