Pregnancy outcome in pregnant women with oligohydramnios at term pregnancy
Objective: The aim of the study was to assess the pregnancy outcome in pregnant women with oligohydramnios at term pregnancy. Materials and Methods: This is a prospective, case-control study which was conducted at Silchar Medical College and Hospital over a period of one year from July 2016 to June 2017. It included 140 pregnant women at term pregnancy with amniotic fluid index ≤ 5cm. The control group included 200 pregnant women at term pregnancy with amniotic fluid index > 5cm. The two groups were compared. Statistical analysis was done using the Fisher’s exact test to calculate the P value. Results: There was a significantly higher incidence of low fetal biophysical profile, induction of labour, overall caesarean rates and caesarean due to non-reassuring fetal status, fetal distress, low birth weight babies, 5 minute Apgar score ≤ 6, neonatal intensive care unit (NICU) admission rates, hypothermia, meconium aspiration syndrome and perinatal death in the group with oligohydramnios as compared to the group with normal liquor volume. The incidence of instrumental delivery, fetal congenital anomaly, hypoglycaemia, hypoxic ischaemic encephalopathy, neonatal jaundice was higher in the oligohydramnios group but was not statistically significant. Conclusion: Oligohydramnios adversely affects the perinatal outcome. However, a favourable outcome can be expected by good antepartum and intrapartum surveillance and neonatal care.
