Bicocca MJ, Le TN, Zhang CC, et al. - Researchers performed comparison of the diagnostic characteristics of sonographic estimated fetal weight (SEFW) undertaken within 7 vs 8-14 days before delivery for identification of fetal macrosomia (birthweight ≥ 4,500 g). In this multicenter, retrospective cohort study, they assessed 330 non-anomalous singletons with SEFW ≥ 4,000 g by Registered Diagnostic Medical Sonographers conducted within 14 days of delivery. Of these, 250 (75.8%) had SEFW measured within 7 days and 80 (24.2%) had SEFW measured 8-14 days prior to delivery. They observed macrosomia rate of 15.1%. Observations revealed that when the sonographic examination is performed within 7 days of birth, the detection of BW ≥ 4,500 g is significantly higher with SEFW ≥ 4,000 g; this was observed irrespective of maternal diabetes.
