Objective: To evaluate the mode of delivery and perinatal outcomes of oligohydramnios.
Methodology: This descriptive cross-sectional study was done at the Department of Obstetrics & Gynecology, Bahawal Victoria Hospital, Bahawalpur from November 2017 to October 2018. All women presenting with oligohydramnios at >32 weeks of gestation were selected, and ultrasonography was used to confirm oligohydramnios.
Results: Total of 700 patients were in the study. The incidence of oligohydramnios was 3%. Incidence of congenital anomalies was 8%, most of them being the fetal renal tract anomalies. Intrauterine growth restriction (IUGR) was observed in 84(12%), stillbirths in 42(6%), neonatal intensive care unit (NICU) admissions were observed in 125(25%) babies, and early neonatal deaths (ENND) occurred in 42(6%) with or without NICU admissions. No adverse perinatal outcome was noted in 371(43%) babies. Cesarean section was done in 336(48%) patients and 364(52%) were delivered vaginally.
Conclusion: Oligohydramnios is a condition requiring vigilant feto-maternal surveillance and a consultant-led decision regarding the mode of delivery due to increased perinatal mortality and morbidity associated with this condition and to reduce the maternal morbidity associated with caesarean section if decided unnecessarily.
