Assessment of Fetal Weight Using Johnson’s Formula and Ultra sonographically and its Correlation with Actual Birth Weight
Introduction: The estimation of fetal weight is of paramount importance in the management of labor and delivery. The study was conducted to find usefulness of clinical estimation of fetal weight as it is useful for developing countries where ultrasonography facilities are unavailable in many areas. Aim: The study aimed at determining accuracy of fetal weight estimation clinically by Johnson’s formula and ultrasonographical by Hadlock’s method. Material & Methods: A descriptive study in the department of obstetrics and gynecology at a tertiary care hospital in western India was conducted between July 2017-June 2018 on pregnant patients with 37 to 40 weeks gestation after applying inclusion and exclusion criteria. Results: The study group consists of 260 subjects from urban, rural settings and different socio-economic classes. There was positive correlation between actual birth weight and Johnson’s formula weight (R=0.533, P= 0.000) as well as between actual birth weight and esti...
