Özet

Objectives: The aim of the study to compare the accuracy of

different ultrasonographic weight estimating equations for

predicting the fetal weight in pregnant patients on insulin

therapy.

Design: Prospective clinical study

Setting: Erciyes University Obstetric Clinic Perinatology

Unit, Turkey

Subjects: One hundred and eleven diabetic pregnant women

using insulin

Intervention(s): The fetal weight estimations were calculated

off-line using the two previously investigated methods

(Hadlock 1 and Shepard) and abdominal circumference

(AC).

Main outcome measure(s): The accuracy of different weight

estimating equations for predicting fetal weight in pregnant

patients on insulin therapy

Results: Hadlock 1 and Shepard methods had estimated fetal

weight values close to the actual birth weight whereas AC

had not. The success rates and the sensitivity of the methods

for detecting macrosomic fetuses weighing over 4000 g in

insulin using diabetic women were low and the rates were

0.65 (95% CI: 0.40-0.84), 0.13 (95% CI: 0.01-0.40) and 0.55 (95%

CI: 0.31-0.76), for the Hadlock 1, AC and Shepard formulae

respectively (P<.05).

Conclusion(s): The study showed that Hadlock 1 and Shepard

methods were significantly better for estimating fetal weight

than AC. The success rates of the methods for detecting

macrosomic fetuses weighing over 4000 g were similar, but

the methods did not have high sensitivity.
