Objectives: To study the maternal and foetal outcome in normal term pregnancy with isolated oligohydramnios. Methods: This was a prospective study conducted in the department of obstetrics and gynaecology at BGS Global Medical college, Bangalore over a period of one year from January 2015 to December 2015. A total of 100 patients of gestational age >37 weeks matched for age and parity were studied, of which the study group had 50 women with an AFI less than 5 and the control group had 50 women

Results: Non stress test (NST) was reassuring in 39 patients (78%) in the study group and 46 patients (92%) in the control group (p value <0.05) and was found to be statistically significant. In the study group, 16 of the 50 patients (32%) had normal vaginal delivery, 9 patients (18%) had instrumental delivery and 25 patients (50%) underwent caesarean section, whereas 34 of the 50 patients (68%) had normal vaginal delivery, 2 patients (4%) had instrumental delivery and 14 patients (28%) delivered by caesarean section in the control group (p value <0.05). This difference was statistically significant. Apgar score <7 was seen in 9 patients (18%) win the study group and in 6 patients (12%) in the control group (p value >0.05). The difference was not statistically significant. 22 babies (44%) in the study group had birth weight <2.5 kg, whereas 10 babies (20%) in the control group had birth weight <2.5 kg (p value <0.05). This difference was statistically significant. 6 babies in the study group (12%) were admitted to the neonatal intensive care unit (NICU), whereas 4 babies (8%) in the control group had NICU admission (p value >0.05). The difference was not statistically significant. All the babies were stable at the time of discharge. There were no babies needing ventilatory support and no perinatal deaths in either the study or control groups. Conclusion: Isolated oligohydramnios without any complicating factor is not associated with adverse perinatal outcome, though the babies may have a lower birth weight.
