COMPARISION OF EFFICACY OF DIFFERENT TECHNIQUE FOR ESTIMATING FETAL WEIGHT DURNING PREGNANCY

Ashish Zarariya, Vivek L Durge, Jitendra Deshmukh

Abstract


Introduction: Fetal Weight estimation at term is an important factor for prevention of prematurity, evaluation of
fetopelvic disproportion, induction of labour, mode of delivery and detection of IUGR. Method: This is prospective
study conducted on 226 women at Government Medical College, Nagpur from November2017 to August2018 which included singleton
pregnencies after 37 weeks of gestation with cephalic presentation without any maternal or fetal complication and delivered within 48
hours of estimation of fetal weight. Fetal Weight was estimated using clinical formula(Johnsons and Dares) and ultrasonography(Hadlock)
and results were compared with actual birthweight. Results: Out of 226 cases analysed statistically ultrasonography is most accurate
followed by Johnsons formula and least efficacy was with Dares formula, however percentage error of Johnsons and Hadlock formula is
comparable. Conclusion: Although ultrasonography is best method for estimation of fetal weight clinical method specially Johnsons
formula can be effectively used in low resourse setting and should be taught to all health workers
