Abstract

Background: Oligohydramnios is a condition where the liquor amnii is deficient in amount to the extent of less than 200ml at term. Maternal complications can be prolonged labor due to inertia, increased operative interference. Methods: The present hospital based study was conducted in the department of obstetrics and gynaecology, East Point hospital, Bidrahalli, Bangalore, Karnataka, India. Duration of the study was for 6 months from November 2015 to April 2016. All pregnant women of gestational age >37 weeks attending the outpatient department were subjected to routine ultrasound examination. Results: Out of the total 410 pregnant women of gestational age >37 weeks in the study duration, the incidence of oligohydramnios was found to be 14% (n=58). 36 patients (62%) underwent lower segment caesarean section with fetal distress being most common indication for it. Incidence of low birth weight (<2.5 kg) was seen in 22 newborns (38.6%). One fourth of them had Apgar score less than 7 at 1 minute and 10 babies had less than 7 score at 5 minutes. Neonatal intensive care unit (NICU) was required in 23 newborns (40%). Conclusions: A higher incidence of oligohydramnios was seen in the present study with increased maternal and perinatal complications associated with it.
