Perinatal outcome in cases of borderline oligohydramnios

Abstract

Introduction: Oligohydramnios is associated with intrauterine growth restriction, congenital anomaly, neonatal and maternal morbidities. The outcome in cases of borderline oligohydramnios is less clear. This study was performed to document fetal, neonatal and maternal outcome in cases of borderline oligohydramnios among those women who delivered in our unit. Materials and Methods: The duration of the study was July 2013-June 2016 and a total of 66 women who were more than 37 weeks gestation were included. The data was compared with 66 control women from the same institution. Results: Overall 45.4%% cases were delivered normally while 62.5% of the control group had a vaginal delivery (p=0.02). Emergency caesarean section cases were due to fetal distress in 35.29% of cases compared to 8.6%in the control group (p=0.02).The fetal and neonatal outcome was far better in the control group as there was 45 versus 8 cases where there was a neonatal problem (p< 0> Conclusions: Cases of borderline oligohydramnios at term have a higher risk of perinatal complications and operative delivery and should be monitored during labour. Delivery should preferably be in a unit where excellent neonatal facilities are available. Keywords: Oligohydramnios, Caesarean section, Intrauterine growth restriction, Meconium.
