Abstract :
Objective: To study and analyse the neonatal outcome and appropriate route of delivery in oligohydramnios of AFI < 5 cm at or beyond 34 weeks gestation.
Methods: In this prospective case control study of 50 women (study group) with ultrasound diagnosis of oligohydramnios of AFI < 5 cm at or beyond 34 weeks of gestation was compared with 50 women (control group) with AFI > 5 cm and less than 25 at or beyond 34 weeks matched for age, parity, gestational age. Women with PROM, gestational age < 34 weeks and greater than 40 weeks, congenital anomaly, PIH, multiple gestations were excluded from this study. Pregnancy was assessed with respect to antepartum, intrapartum and neonatal outcome measures.
Results: In our study we found that oligohydramnios was associated with increased rate of non reassuring fetal heart rate (20% Vs 4%), labor induction (28% Vs 2%), cesarean delivery (56% Vs 8%), low birth weight (62% Vs 24%), IUGR (18% Vs 2%) and admission to NICU (18% Vs 4%). No difference in occurrence of meconium stained liquor, Apgar score < 7 at 5 minutes was found. There was no neonatal death in the study.
Conclusion: Pregnancies with isolated oligohydramnios (AFI
