Correlation of Ultrasound (Hadlock Method) in Estimating Antepartum Fetal Weight Keeping Actual Weight at Birth as Gold Standard
Abstract
Objective: To determine the link between ultrasonography and antepartum fetal weight, keeping the actual weight at birth as the gold standard.
Methods\ology: This cross-sectional validation study was conducted at dept. of Radiology, KRL Hospital Islamabad from January 1st, 2020 until July 1st 2020. Non-probability convenient sampling was used to choose and analyze 64 patients. At the time of delivery, the newborn's exact weight was recorded. The SPSS software (version 17.0), was used to analyze the data, and the results were interpreted using descriptive and inferential statistics.
Results: At a mean gestational age of 37 weeks, with a standard deviation of 1.2 weeks. The study included a sample size of 64 pregnant women who presented to the department of radiology. According to ultrasound estimates, the fetus weighed 3006.9+/-292 grams, however the baby weighed 3000.5+/-305 grams after birth. Hence, it is concluded that there is a significant positive correlation between the sonographically estimated fetal weight and the actual fetal weight.
Conclusions: We conclude that the sonographically estimated antenatal birth weight and the actual birth weight are indistinguishable, hence antenatal ultrasound can be used with confidence to determine birth weight.
