Abstract:

Objective:To evaluate fetal weight by clinical and ultrasound methods and its correlation to actual birth weight.Methods:This study was cross sectional study of fetal weight estimation in Antenatal women with term gestation (37-42) weeks of gestation with vertex presentation,who hadgestational age confirmed by dates and ultrasound scanning of< 22 weeks admitted in antenatal clinics and maternitywards prepared for elective caesarean section within 24 hours. from September 2018 to march 2019. Included 84 women with singleton pregnancy, full term whowereadmittedinlabour room ofObstetrics and Gynecology department in Zagazig University Hospital.Results:comparisonbetween clinical and ultrasound methods at different gestational ages, the mean fetalweight was significantly higher in the clinical method at 37 and 38 weeks, while not reach significant level at 39 and 40 weeks. Both the methodshad moresensitivity inbirth weightrange 2500-4000gm than <2500gand >4000g. The Hadlocks formula is more accurate than Johnson’s formula the Sensitivity of ultrasound is 82.0 % higher than clinical 76.7 %.Conclusions:Antenatal fetal weight can be estimated with reasonable accuracy, by ultrasounography using Hadlocks formula and clinically using Johnson's formula. Hadlocks formula is more accurate, reliable and showed better sensitivity and specificity in detecting fetal weight than Johnson’s formula.
