Oligohydramnios is frequently used to identify at risk fetuses. The purpose of this study was to assess adverse perinatal outcomes in oligohydramnios. Subjects comprised pregnant women diagnosed either with (590) or without (597) oligohydramnios who delivered after hospital admittance from 2000 to 2010 . Data, including the resuscitation of newborn, Apgar score at 5 min, NICU admission, death in 24 hours after birth, still birth, intrauterine growth restriction, fetal distress, meconium passage, and neonatal birth weight were abstracted from records. Chi – square, Fisher’s exact test, and t tests were used for analysis. An amniotic fluid index of 5 cm or less had a higher rate of meconium passage. Antepartum oligohydramnios is associated with an increased risk of perinatal morbidity and mortality.
