Pregnancy outcome in patients with oligohydramnios at or beyond 34 weeks of gestation

Objectives: To study the effects of decreased Amniotic fluid Index (AFI≤5cm) on pregnancy outcome at or beyond 34 weeks of gestation. Methods: Prospective comparative study conducted in Department of Obstetrics and Gynaecology, SMS Medical College, Jaipur from Feb. 2013 to Oct. 2014. An analytic study comparing maternal and fetal outcomes in women with AFI ≤ 5 vs women with AFI > 5 in primigravida was designed. Results: AFI ≤ 5 was associated with higher number of labour induction (44.29% vs 22.86%) and LSCS (45.71% vs 35.71%) in mothers, increased incidence of low APGAR score (18.57% vs 2.86%), low birth weight (35.72% vs 8.57%), NICU admissions (17.14% vs 5.71%) and deaths (5.71% vs 1.43%) in neonates as compared to AFI > 5. Conclusion: Thus we conclude that oligohydramnios is associated with increased maternal morbidity and fetal morbidity and mortality. Early diagnosis and prompt management is essential. Antenatal and intrapartum monitoring will improve the perinatal outcome.
