40 week ultrasound weight accuracy

"The accuracy of these ultrasounds depends on the skill of the technician and … J Am Sci 2013;9(12):798-802]. The calculations can give an average weight consistent with these measurements, but can be off by as much as 1/2 to 1 pound when performed by an experienced sonographer. The accuracy of Ultrasound in Estimation of fetal weight. Most physicians can detect a … estimated fetal weight (EFW) with the baby’s subsequent weight at birth, for preterm and term gestations. It has an accuracy similar to that of clinical ultrasound examination for delivery at or beyond 37 weeks' gestation, whereas it is significantly superior to clinical estimates of weight for preterm birth 6. One study found prenatal ultrasound diagnosis of prediction of birth weight to be no more accurate than maternal or clinical predictions of infant birth weight [39]. Unfortunately, the science of weight estimations is quite imprecise. Although substantial research has investigated the most accurate ultrasound formula for calculating estimated fetal weight, current evidence indi … Ultrasound estimation of fetal weight is a highly influential factor in antenatal management, guiding both the timing and mode of delivery of a pregnancy. Please share your experiences with the estimates given from ultrasounds vs. actual birth weights. CONCLUSIONS • Ultrasound biometry is overall a quite accurate means for the estimation of fetal weight in routine practice. Keep in mind that this is only an estimate. The purpose of this study is to compare the accuracy of EFW formulas in patients with PPROM, and to further evaluate the … Around week 20, an ultrasound might be used to detect fetal abnormalities. So they were way out! Ultrasound fetal biometry is routinely used to calculate estimated fetal weight (EFW). Usually on the high side, but sometimes on the low side, so I guess I'm looking for validation. Numerous formulas for EFW have been published but have not been validated in pregnancies complicated by preterm premature rupture of membranes (PPROM). My baby boy was born a 41 weeks 1day at 7.8lbs. The secondary outcome was to compare the accuracy of ultrasound with that of the most commonly reported maternal and pregnancy variables, including age, BMI, gestational age at assessment, and Bishop score, in predicting spontaneous onset of labor before 40 weeks of gestation. It is concluded that predicting fetal weight using the formula witch derived by Hadlock et al is accurate and valid and will be useful in our environment. EFW is a useful parameter with which to predict birth weight and outcome when it is calculated a few days before delivery. Accuracy of the EFW is reported to be best when examinations are performed within 7 days before delivery [38]. The ultrasound is more accurate during the first trimester, and early in the second trimester, it is accurate to within a week. The research I've done, just today, on estimated weight vs. actual birth weight is astounding in that at least 50% of the time the estimate is WAY off. Good job I stuck to my guns and said no because he could have well been user weight. Background Estimation of fetal weight (EFW) by ultrasound is useful in clinical decision-making. The aim of this study was to determine the accuracy of established ultrasound EFW formulae to identify small and large for gestational age fetuses when used after 35 weeks gestation.
