Foeto-maternal outcome in oligohydramnios

Background: Oligohydramnios is defined as an amniotic fluid index (AFI) of ≤5 cm. AFI is calculated by adding the depth in centimetres of the largest vertical pocket in each of four equal uterine quadrants in ultrasonography. We aimed to evaluate the predictive value of amniotic fluid index (AFI) (≤5 cm) for mode of delivery, associated complications, perinatal outcome, birth weight, meconium staining and APGAR scores.Methods: This was a prospective study of 100 antenatal women who presented at our antenatal OPD at GMERS Medical College and Civil Hospital, Sola, Ahmedabad, Gujarat with gestational age between 34 and 41 weeks over a 1-year duration from 2020 to 2021. The women’s history was taken, clinical examination done, and AFI was measured, and results were tabulated.Results: Prevalence was most among the 20-30 age group. Most patients delivered vaginally. Anaemia and gestational hypertension were the most common associated complications. There was no neonatal death in this study. No significant correlation was found between oligohydramnios and low birth weight babies.Conclusions: Oligohydramnios has a significant correlation with caesarean section for foetal distress and low birth weight babies.
