Perinatal Outcome Of Term Pregnancies Complicated By Oligohydramnios

Abstract

Background: To study the perinatal outcome in Oligohydramnios (AFI < 5) at term & find out incidence of relation of maternal high risk factors.

Methods: A Prospective cohort study of 30 women diagnosed to be having Oligohydramnios on ultrasound at 37 weeks of pregnancy was conducted in an obstetric hospital situated in an urban area. The patients were enrolled in this study on the basis of predefined inclusion and exclusion criteria.  Detailed history was taken in all the patients. General and systemic examination was done. Perinatal Outcome was studied in terms of birth asphyxia, presence of anomalies, need for admission to NICU and neonatal mortality. Odds ratio were calculated at appropriate associations. P < 0.05 was considered as significant. The data was tabulated and analyzed using SPSS 16.0 version software.

Results: Our study found that Oligohydramnios at term pregnancy was associated with increased incidence of nonreactive NST, meconium stained amniotic fluid, birth asphyxia, respiratory distress immediately after birth, congenital anomalies, need for admission to NICU and neonatal mortality.

Conclusions: Oligohydramnios diagnosed on ultrasound at or after term (37 weeks) is associated with adverse perinatal outcome. The possibility of congenital anomalies, birth asphyxia and need for NICU admission in immediate postnatal period makes it necessary that such patients be delivered at an appropriate centre having NICU facilities.
