how accurate is estimated fetal weight

A systematic review of the ultrasound estimation of fetal weight. In order to utilize our EFW measurements for antenatal management and delivery recommendations, improvements in our biometric measurements should strive for improved error rates of <5–10%. Department of Perinatal Medicine, King George V Hospital, Sydney, New South Wales. The accuracy of ultrasound estimated fetal weight has improved in the last decade, though a lack of consistency remains evident. Clinical EFW was obtained before rupture of the membranes by the attending senior resident, … The BPD is used to estimate fetal weight and gestational age. Visit our ABOG MOC II collection. Scans done at 40 weeks and beyond were more accurate than those done preterm. Findings from a UK birth cohort with independent validation. 10. In practice the most common equations for calculating the estimated fetal weight (EFW) are reported to be the Shepard and Hadlock formulas [5,8,9]: Shepard: Log 10 (weight) = -1.7492+ 0.166*BPD +0.046*AC - 2.646* (AC*BPD)/1,000. Precise estimated fetal weight is necessary to provide adequate and accurate counseling to our patients. Seven studies met the inclusion criteria and 11 different formulae were assessed; ultrasound calculation of fetal weight was most commonly overestimated. Due to the inherent error associated with ultrasound measurements, the accepted overall margin of error between EFW and actual birth weight (ABW) is 15%.
