A clinical study of feto-maternal outcome in pregnancies with oligohydramnios

Background The amniotic fluid that surrounds the fetus serves several roles during pregnancy. Oligohydramnios is diagnosed when ultrasonographically the AFI is less than 5cm/5th percentile. It affects 3-5% of all pregnancies. Assessment of amniotic fluid volume is a helpful tool in determining who is at risk for potentially adverse obstetric and perinatal outcome.

Methods Pregnant women with oligohydramnios reporting to Cheluvamba Hospital, attached to Mysore Medical College and Research Institute, Mysore from December 2012- June 2014 were included in the clinical study of maternal and fetal outcome. All singleton, non-anomalous, low risk pregnancies with AFI≤5cm with intact membranes and gestational age between 28-42 weeks were included in the study. Various outcomes such as mode of delivery, meconium staining, Apgar at 1 and 5 minutes, birth weight and NICU admissions were assessed.

Results A total of 130 cases of isolated oligohydramnios were assessed. 55.4% had vaginal delivery. 13.8% underwent elective LSCS and 30.8% had emergency LSCS. 18.5% had meconium stained liquor, 4.6% babies had APGAR of <7 at 5 minutes. 17.7% had birth weight of <2.5 kg and 6.9% of babies required NICU admission.

Conclusions The present study was conducted to know the feto-maternal outcome in pregnancies with oligohydramnios. The study showed that isolated oligohydramnios had no adverse maternal or perinatal outcome.
