| Abstract Objective: To evaluate how far clinical and sonographic fetal weight assessment done by obstetrician can coincide and outline their correlation with the actual birth weight of the newborn. Study design and setting: This cross-sectional study was conducted at AL-Elwiya Maternity Teaching Hospital in Baghdad between Sept. 2009 to Sept. 2010. Material and methods: The study sample consisted of 100 singleton term pregnant women (completed 38 weeks) with cephalic presentation and intact membranes; they were admitted for early labour or for induction of labour or cesarean section. Their gestational age determination depended on precise LMP and early pregnancy ultrasound (<20 weeks). Fetal weight estimation was done using Johnson's formula and sonographic weight estimation by Hadlock's formula. Immediately after delivery the newborns were weighed by using digital balance. Results: Fetal weight estimation by clinical method is relatively accurate and comparable to ultrasound. The clinical fetal weight estimation is more accurate than ultrasound method when fetal weight is >3kg (p-value 0.907), while ultrasound is more accurate than clinical when fetal weight is <3kg (p-value 0.535). Conclusion: Clinical fetal weight estimation is proved to be a relatively accurate and comparable to ultrasound. The study also proved that clinical estimation is better than ultrasound when actual fetal weight is more than 3 kg. Key Words: Fetal weight, Johnson's formula, Hadlock's formula | ||
