Abstract

 

Background: Birth weight of an infant is the single most important determinant of newborn survival & is a standard routine antepartum evaluation in high risk pregnancies. The present study was aim to estimate of fetal birth weight clinically and sonographically and compare them with actual birth weight after delivery of fetus.

Material & Methods: This is a descriptive type of observational study done on 100 full term pregnant woman who have been admitted in Department of Obstetric and Gynecology, SMS Medical College and Hospital, Jaipur (Raj.) from April 2017 onwards. All the examination was performed by a single person to avoid the bias. This measurement was recorded in the checklist and EFW were calculated by applying this information Johnson’s formula & Hadlock formula.

Results: Our study showed that the majority of cases (60%) were seen in 21-25 years of age. The mean age of patients was 24.34 years. Majority of the birth weight were distributed between 3-3.5 kg, P value for both Hadlock formula and Johnson’s formula were 0.5 i.e.>0.05 not significant. The mean birth weight of Johnson’s formula is closest to the mean of actual birth weight. Average error is least between 2.5-3.0 kg in both the groups.

Conclusion: We regard the overestimation of foetal weight by the clinical method as a positive factor since it will enhance the sensitivity of health workers at peripheral centres if properly taught to them for earlier referral of mothers with macrosomic foetuses, thus contributing to reduction of obstructed labour and its sequelae.

Keywords: Birth weight, Hadlock formula, Johnson’s formula, Fetal weight.
