Accuracy of Sonographic Fetal Weight Estimation in Bangladesh

ObjectiveThis study was conducted to determine the accuracy of estimated fetal weight (EFW) by ultrasound, compared with birth weight (BW), in Bangladesh.MethodsThis is a prospective, cross-sectional study on well-dated singleton fetuses. The accuracy of weight-prediction formula is determined by assessing how well the formula works in a group of fetuses scanned close to delivery. Results of previous studies were compared with those of this study.ResultsA total of 73 infants were included in the analysis to determine the accuracy of EFW. The mean absolute difference between ultrasound EFW and BW was −64.5 (±218.5) g, and the mean relative difference or the mean percentage error of fetal weight estimation was −1.4% (±7.6%).ConclusionUltrasound is a reliable modality for estimating fetal weight in a Bangladeshi population using the head circumference, femur length, and abdominal circumference formula of Hadlock.
