Comparative Evaluation between Two Clinical Methods of Fetal Weight Estimation with Actual Birth weight ? A Prospective Study

Objective Comparative evaluation of fetal weight using two clinical methods- Johnson-s and Dare-s formulae to the actual birth weight of the baby. Methods The fetal weight in utero was estimated in 150 antenatal women at term using two clinical formulae- Johnson-s and Dare-s and compared with actual birth weight of the baby - comparative analysis done. Results Demographic data like age, gravidity analysed. Average error and maximum error of the two clinical methods in each group calculated. In 95 % of cases, fetal weight was within 15 % error with both clinical methods. Conclusion 85.5 % of total cases were in the group of fetal weight 2500-3500 grams most commonly seen in the routine practice and in this group both the clinical methods had reasonable accuracy in estimating fetal weight.
