Abstract :

Objective:To make comparative evaluation of estimation of fetal weight in term pregnancy by using a) abdominal girth * symphysiofundal height b) Hadlock�s formula using ultrasound c) Johnson�s formula d) dawn�s formula Methods: fetal weight in utero is calculated by using above methods in 200 term pregnant women and the results were correlated with actual birth weight. Comparison done by various methods. Results: average error was least in AG*SFH method. Maximum error was in Dawns formula and least in AG*SFH and Hadlocks i.e.75.9% of cases came within 30% of birth weigth by both AG*SFH and Hadlocks method. Standard deviation of predicyion error was least with Hadlocks methof followed by AG*SFH. Conclusion: AG*SFH is the best predictor and is used in day to day practice. Hadlocks method had more accuracy but is done in places where facilities are available.
