A study of maternal and fetal outcome in third trimester diagnose case of oligohydramnios

Vibha Moses, Sarita Thakre


Background: Oligohydramnios is defined as when the maximum vertical pockets of liquor is less than 2 cm or when AFI is less than 5 cm or less than 10th centile. Amniotic fluid is part of the baby” life support system during labour so the purpose of this study is evaluate maternal and perinatal outcome in present study.

Methods: 150 patients with third trimester diagnosed case of oligohydramnios were included and were screened through exclusion and inclusion criteria.

Results: Oligohydramnios was more in primipara in our study. It was increase in case of prolonged pregnancy. 66% were of moderate AFI and 29% were severe oligohydramnios. Idiopathic was most common cause, and .second cause was PIH. Oligohydramnios was related to higher rate of IUGR and NICU admission.

Conclusions: Now a day oligohydramnios is most common occurrence in pregnant women. Amniotic fluid volume is a predictor of fetal tolerance in labour and its decrease is associated with increased perinatal morbidity and mortality, rates of caesarean section are rising. Take timely intervention can reduce perinatal morbidity and mortality. Vaginal delivery and caesarean section should be well balanced so that unnecessary maternal morbidities prevented and improve labour outcome.
