A comparative study on estimation of fetal weight in term pregnancy by clinical methods and USG with actual birth weight in a tertiary care center
Keywords:
fetal birth weight, ultrasound, Johnsons formula, Dares formula, Hadlocks formulaAbstract
Background: Primary goal in modern obstetrics is to deliver a healthy baby in a healthy mother. Birth weight is the most important factor in determining the neonatal outcome and survival.1 So the accurate estimation of fetal weight is one of the important aspects in management of labour.2 objectives: To compare the accuracy of estimated fetal weight by USG and clinical methods with actual birth weight. Material & Methods: Study Design: Prospective hospital based cross – sectional study. Study area: Department of Obstetrics & Gynaecology, Modern Government Maternity Hospital, Osmania Medical college, Petlaburj, Hyderabad, Telangana state. Study Period: Feb. 2021 - Jan 2022. Study population: Pregnant women attending Obstetrics and Gynaecology department, Modern Government Maternity Hospital, Osmania Medical college, Petlaburj, Hyderabad. Sample size: Study consisted a total of 200 cases. Results: There was no significant difference between actual birth weight and USG, Johnson and Dare’s formula estimated weight. It is inferred that all the methods are more or less accurately estimated the actual birth weight. But, when compared to the other two methods, USG estimate was more accurate as the mean difference between USG estimate and actual birth weight was found to be very less ie. 13.00 g.
