Abstract:
Aim: To determine the accuracy of ultrasonography in estimation of fetal weight and after deliver birth weight.
Study Design: Prospective, cross-sectional study.
Place and Duration: This research was conducted at Department of Radiology, Sughra Shafi Medical Complex
Narowal from 1st January 2018 to 30th June 2018.
Methods: Two hundred and sixty five pregnant women of ages 20 years to 45 years were included. Patient’s
detailed history including literacy level, socio-economic was noted. Patient’s weight, height and parity were also
calculated. Fetal weight was examine by using ultrasound and compare it to after delivery birth weight.
Results: There were 144 (54.33%) patients were ages between 20 to 30 years, 90 (33.96%) patients were ages
between 30 to 40 years and rest 31 (11.70%) had an ages greater than 40 years. One hundred and ten (41.59%) were literate while rest were illiterate. One hundred and sixty (60.38%) had an urban residency. Patients weight were ranges between 40kg to 90 kg. Minimum fetal weight was observed as 2.30kg while maximum was 3.60kg.
Accuracy of ultrasound resulted 45.28%. Error estimation was noted as 45.28% 33.96% and 20.78% as accurate, over and under estimated.
Conclusion: It is concluded that error estimation of fetal weight was observed that is 100 grams of actual birth
weight. Moreover, rely only on ultrasonography for estimation fetal weight may lead to obstetrical problems.
