Background: Oligohydramnios is a severe and common complication of pregnancy that is associated with a poor perinatal outcome 1. Aim of this study is to identify etiological factors and to suggest measures needed to improve the perinatal outcome in pregnancies complicated by oligohydramnios. Methods: This is a descriptive prospective cross-sectional, hospital-based study, carried out at Dept of Obgy, GGH Jamnagar in the period from Sept 2017 to Aug 2018. The studied population were 100 pregnant women diagnosed as cases of oligohydramnios by sonologists using the criterion AFI less than or equal to 5 The data was collected using questionnaire, labor ward records and NICU records. The collected data were coded in a master sheet and analyzed by computer. Results: 44% participants were belonged to 23 to 27 age group and 58% participants were primigravida. 62% represented the group 13 to 26 weeks gestation. Study found FMC <10 in 51% of participants. 67% patients had c/f of PET. 47% delivery was done by vaginal route. 6% babies were still born and prematurity was the most common cause of still birth. Around 56% babies were low birth weight and congenital anomalies were present in 1% babies. APGAR score measured <7 at 1 minute was in 47% and <7 at 5 minutes was in 29% babies. 3% babies had NSAID exposure and perinatal mortality amongst those not protected by betamethasone coverage was 5%. Conclusion: Various risk factors that lead to oligohydramnios are identifiable and recognition of risk factors for oligohydramnios constitutes a part of basic prenatal and antenatal care. Routine AN corticosteroids coverage in patients of oligohydramnios and i.v. hydrotherapy can improve the perinatal outcome in pregnancies complicated by oligohydramnios. 5 min APGAR score, either alone or in combination of 1 min score instead of only 1 min score alone, is a better predictor of neonatal outcome.ELLSCS is the preferred mode of delivery and induced vaginal delivery is discouraged in cases of oligohydramnios.
