Abstract: Objectives: To determine the ultrasound accuracy of estimated fetal weight in small for gestational age and appropriate for gestational age pregnancies and compare ultrasound accuracy in the two groups. Method: In a Prospective randomized observational study 50 pregnant women at term with AGA pregnancy and 50 other women at term with SGA pregnancy were included and ultrasonic estimation of fetal weight was performed within a week of delivery. Result: In present study, EFW overestimated birth weight in a total of 69% cases and underestimated in 31% cases. Underestimation was more in SGA cases (40%) as compared to AGA (22%). Overestimation was more in AGA (78%) cases as compared to SGA (60%) cases. The mean absolute error of EFW for estimation of birth weight was more in AGA neonates (154.4 ? 266.2 gm) as compared to the SGA neonates (45.96 ? 191.3 gm) (p=0.021). The mean relative error of EFW for estimation of birth weight was more in AGA neonates (5.70 ? 9.08%) as compared to the SGA neonates (2.15 ? 8.75 %) (p=0.049). Conclusion: Ultrasound estimation of fetal weight in small for gestational age pregnancies is comparable to accuracy of estimation of fetal weight in appropriate for gestational age pregnancies.
