ABSTRACT
Introduction: Fetal weight estimation is considered one of the most significant criteria for perinatal mortality and morbidity assessment. It is very important for the prevention of prematurity, evaluation of pelvic disproportion before induction of labor and detection of labor and detection of intrauterine growth restriction. For estimation of fetal growth, two different routine methods are commonly used clinical examination and ultrasonography.
Materials and methods: The study was performed to determine the fetal weight in term pregnancy using abdominal girth x symphysis fundal height (Insler’s formula), Johnson’s formula and Hadlock’s formula using ultrasonography. All the measurements were taken and the results were compared to the actual birth weight.
Results: Out of 200 participants, 98 underwent full term vaginal delivery (FTND) and 102 participants underwent lower segment cesarean section (LSCS) which was reported to be high in the present study i.e. 51%. The mean birth weights by two methods symphysis-fundal height * Abdominal girth (AG) and actual birth weight were statistically insignificant in the present study. It was also found that, the mean birth weights by Johnson’s formula and Hadlock’s formula with actual birth weight are statistically significant.
Conclusion: Of the three clinical formula’s studied; Insler’s formula has better predictable results in fetal weight estimation, compared to Johnson’s and Hadlock’s formula. Clinical estimation of birth weight clearly has a role in management of labor and delivery in a term pregnancy. It was concluded from the study was sonographic examination is more accurate in assessing fetal growth and estimating fetal weight than clinical examination.
