Amniotic fluid estimation by ultrasound is an essential component of fetal assessment in utero. The present study aimed to measure and compare two semiquantitative methods of estimation of amniotic fluid i.e. single deepest vertical pocket with amniotic fluid index in prediction of adverse pregnancy outcomes.
Methods: Study included 120 booked pregnant women of 34 to 41weeks POG who were followed till minimum 48hours after delivery. They were divided in to two groups of 60 each, in Group-I, amniotic fluid volume estimation was done by Amniotic Fluid Index (AFI) and in Group-II by Single Deepest Vertical Pocket (SDVP) technique. AFI ≤5cm in group-I and SDVP<2cm in group-II were identified as Oligohydramnios and feto-maternal outcomes were compared.
Results: Oligohydramnios was diagnosed in 4 (7%) in group-I and 5 (8%) patients in group-II which was statistically not significant. Biophysical scoring, doppler parameters, induction of labour, intrapartum CTG, rate of cesarean section and admission to NICU were not statistically different in both the groups.
Conclusion: Both AFI and SDVP techniques for amniotic fluid volume (AFV) estimation were similarly effective in diagnosing oligohydramnios and predicting adverse pregnancy outcome.
