Fetal Weight Prediction in 3rd Trimester by Ultrasonography.

Abstract

Fetal weight estimation is a common obstetrical practice now-a-days. It guides clinicans to finalize important obstetrical decision. The antenatal ultrasound measurement of the fetal parameters; abdominal circumference and head circumference were compared with birth weight of new –born delivered within 72 hours of measurement. Birth weight was highly correlated with head circumference (γ=0.95). Fitted linear regression equations were calculated relating birth weight to the two ultrasound factors. A liver combination of abdomen circumference and head circumference values was better than abdomen circumference alone to predict birth weight.
