Abstract :
Introduction: Oligohydramnios, defined as when the AFI is less than 5. Definition of increased or decreased amniotic fluid volume are based on sonographic criteria. Oligohydramnios complicates approximately 1 to 2% of pregnancies Amniotic fluid provides the cushion effect against the constricting confines of the gravid uterus. It creates space and helps in musculoskeletal development of foetus, helps in normal fetal lung development and prevents compression of umbilical cord, placenta and hence protects the foetus from vascular and nutritional compromises. Oligohydramnios is associated with high risk adverse perinatal outcome like fetal distress, meconium aspiration, low APGAR, joint contracture, pulmonary hypoplasia etc., and associated with maternal morbidity in the form of increased rates of induction and/or operative interference. This study is conducted to find out the effects of oligohydramnios in determining the obstetric and perinatal outcome.
Objectives: To study, 1) Primary outcome- Obstetric outcome in terms of mode of delivery, indication for operative interference. 2) Secondary outcome- Neonatal outcome in terms of birth weight, Apgar score, colour of liquor, admissions to NICU.
Materials and Methods: This is a prospective observational study conducted on 80 patients presenting to Department of Obstetrics and Gynecology at KIMS hospital, Bengaluru from January 2019 to June 2020 who were diagnosed with oligohydramnios with intact membranes with AFI
Results: A total of 80 cases of Isolated Oligohydramnios were assessed. 38.7% cases delivered vaginally, 61.2% of cases underwent Cesarean section, 15% had meconium stained liquor, 15% had APGAR score of
Conclusion: The present study was conducted to know the fetomaternal outcome in pregnancies with oligohydramnios. The study showed oligohydramnios was associated with higher rates of induction and Cesarean section and associated with Low birth weight babies.
