Estimation of amniotic fluid volume is a good predictor of maternal and perinatal outcome. Oligohydramnios is due to anamolies of fetus and functional disorders of mother , fetus and placenta. A prospective hospital based study of hundred antenatal women conducted at Guntur Government Hospital (GGH) Guntur Medical College , Guntur from October 2007 to October 2008. Oligohydramnios influence both maternal and perinatal outcome .There is increased incidence of instrumental deliveries and caesarean sections in the pregnant women with oligohydramnios. It increases the incidence of adverse perinatal outcomes like fetal distress, meconium stained liquor , low APGAR scores , low birth weight , NICU admission , perinatal morbidity and mortality. The incidence of oligohydramnios is more in unbooked cases. In this study PIH can be attributed to be one of the aetiological factors of oligohydramnios. The incidence of instrumental deliveries and caesarean section rates(58%) are high when compared to control group. The incidence of fetal distress(40%), meconium stained liquor (36%), low APGAR (20%), low birth weight(56%), and NICU admissions (34%) when compared to control group..
