Fetomaternal outcome in cases of oligohydramnios after 28 weeks of pregnancy

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.
