| Abstrakt: | Objectives: The estimation of prognostic value of ultrasonography in fetal weight assessment. Design: Assessment of practical value of ultrasonography in full term newborns. Material and Methods: We have retrospectively analyzed the outcomes of 611 ultrasonographic studies. It was divided into three groups: K, B, BD in relation to weight of newborns. According to that K group involved 302 newborns weighing between 2500-4000 g, B group 262 of newborns weighing more than 4000 g, BD group (47 cases) with weight exceeding 4500 g. Expected fetal weight were determined by using Shepard's algorithm. The single factor variance analysis with multiple coparison test was applied for assessment of mean errors of predicting fetal weight. Results: The highest absolute value of error of expected weught of newborns occured in the group of the newborns wieghing more than 4500g in comparison with its real weight stated just after delivery (p<0,05). The underestimation of fetal weight appeared with incresing newborn weight (beta, 1 BD groups). The overestimation of fetal weight was found in the group of the newborns between 2500-4000 g (p<0,05). Conclusions: The prognostic value of Shepard algorithm in predicting fetal weight is the most accurate for fetuses weighing between 2500-4000 g. The result of our study indicates U/S was the most useless for the newborns over 4500 g. Obstetricans should take into account other factors affecting fetal growth (maternal, paternal, environmental), especially with suspicion of fetal weight over 4500 g. |
