Reliability of sonographic estimation of fetal weight: A study of three tertiary hospitals in Nigeria
Context: There is a dearth of sonologists in Nigeria, yet sonographic estimation of actual birth weight (ABW) is important in antenatal care. Aim: To determine the reliability of estimated fetal weight (EFW) by sonographers and sonologists in Lagos Nigeria. Settings and Design: In the cross-sectiona...

Aim: To determine the reliability of estimated fetal weight (EFW) by sonographers and sonologists in Lagos Nigeria. Settings and Design: In the cross-sectional study, a convenience sample of 663 healthy women with singleton pregnancy at term was selected. Ethical approval for the study design and consent of participants were obtained. Subjects and Methods: Three sonographers and three sonologists used a single ultrasound scanner with Hadlock-3 algorithm to measure biparietal diameter, abdominal circumference, and femur length in three centers while three midwives used a single neonatal weighing scale to measure ABW. Statistical Analysis Used: Medical® statistical software version 12.5 was used to analyze data. Descriptive and inferential statistics, as well as Bland/Altman plots were used to determine reliability of EFWs. Results were tested for statistical significance at P ≤ 0.05. Results: Majority (76.2%) of babies had normal weight while mean EFW and ABW were 3.50 ± 0.10 kg and 3.45 ± 0.12 kg, respectively and the difference between them is not statistically significant (P > 0.05). For sonographers and sonologists in each center, mean error and coefficient of variation were very small while Pearson's correlation coefficient as well as intra- and interclass correlation coefficients was very high. Conclusion: Independent estimation of ABW by sonographers in Lagos metropolis was very reliable. Sonography was also highly reliable in predicting macrosomia.http://www.sjmms.net/article.asp?issn=1658-631X;year=2017;volume=5;issue=1;spage=38;epage=44;aulast=EzeEstimationfetal weightreliabilitysonography |
