Fetomaternal outcome in cases of oligohydramnios after 28 weeks of pregnancy

Abstract

Background: Aim of current study was to study the fetomaternal outcome in cases of oligohydramnios admitted in the labour room for delivery. Methods: A prospective hospital based study was conducted at Sharda hospital, school of medical sciences and research, Sharda University, Greater Noida. The study was undertaken over a period of two years from April 2012 to March 2014. Cases of oligohydramnios (AFI ≤5 cm) detected ultrasonographically at the time of admission in labour room were included in the study. The inclusion criteria for the purpose were: 28 completed weeks of gestation with singleton live pregnancy, intact membranes and no foetal anomalies. Data regarding bio-social characteristics, maternal and perinatal outcome were collected and results were analysed. 40 cases (with similar age and parity profile, as study cases) were taken as control. Results: There were 1342 deliveries during the study period. 41 cases were detected to have oligohydramnios. Majority of the cases (80.49%) in the study group belonged to the age group of 20-30 years. Incidence of associated maternal and foetal complications was higher in cases with oligohydramnios. Perinatal mortality was 9.76%. Fetal heart rate abnormalities were observed in 19.51% cases at the time of admission. Low Apgar score was seen in 19.51% neonates and 36.59% neonates were admitted in NICU. Conclusions: Oligohydramnios is being detected more often these days, due to routinely performed obstetric ultrasonography. In the present study, cases with AFI of ≤5 presenting for delivery (after 28 weeks of gestation), were studied. Babies were relatively more prone for complications.
