A comparative study of perinatal outcome in pregnancies complicated with isolated oligohydramnios and oligohydramnios with intrauterine growth restriction

Abstract

Objective: To study the perinatal outcome in pregnancies complicated with isolated oligohydramnios and oligohydramnios with intrauterine growth restriction (IUGR). Materials and Methods: A prospective comparative study of perinatal outcome in pregnancies complicated with isolated oligohydramnios (Amniotic fluid index (AFI) <8) and oligohydramnios with IUGR (fetal weight < 10th percentile) was carried out in women between 28-40 weeks of gestation in KMCH, Guntur in a period of March 2018-Jan 2020 with a sample of 50 cases with isolated oligohydramnios (AFI <8) and 50 cases with oligohydramnios with IUGR with statistical analysis based on chi-square test. Results: In our study, perinatal outcome in isolated oligohydramnios 90% of babies with APGAR scores > 8 and 28% of babies requiring NICU admission, perinatal mortality is 2%. Perinatal outcome in oligohydramnios with IUGR showing 26% of babies APGAR<7 and NICU admission seen in 48%. Perinatal mortality was 14%. Conclusion: Isolated decreased AFI after 37 weeks of gestation was having better prognosis when compared to oligohydramnios complicating with IUGR. Intense fetal surveillance and proper antepartum and intrapartum care in oligohydramnios can reduce the complications.
