Estimation of Fetal Weight at Term by Clinical Method Using Symphysio Fundal Height and Abdominal Girth and Ultrasound Using Hadlock Formula and Its Correlation with Actual Birth Weight

Abstract

ReseaRch aRticleinjury, intrapartum asphyxia, perineal injuries, and postpartum hemorrhage in mothers with fetuses having macrosomia. 1 It helps in predicting the risk of neonatal morbidity, neonatal intensive IntroductIonPredicting the risk of mortality and morbidity in the 1st year of life largely depends on the weight of the fetus in utero. As fetal weight at birth is one of the prime factors that affect neonatal survival ex utero, an accurate estimate of the weight of the fetus may assist obstetricians and neonatologists in the management of the neonate after birth. It is a routine practice to calculate the weight of the fetus in utero clinically using Johnson's formula, but it is not done after 36 week period of gestation. After the 37 week period of gestation, we depend on USG mode for in utero calculation of the weight of the fetus. In high-risk antenatal women with gestational diabetes mellitus, intrauterine growth restriction and planning for vaginal delivery after cesarean section and estimation of fetal weight at term plays an important role in decision-making. Estimation of fetal weight helps us to make an early decision during labor in case of prolonged labor and malposition, so obstructed labor and its complications can be prevented.During regular antenatal visits, estimation of fetal weight helps us in the early detection of fetuses with macrosomia and growth restriction. Detection of abnormality helps in predicting the risk of complications like prolonged labor, brachial plexus
