Upon arrival to labor and delivery, fetal position and estimated fetal weight should always be documented. Ultrasonography is commonly used to estimate fetal weight despite evidence from a prospective study reporting the sensitivity of clinical and ultrasonographic prediction of macrosomia as 68% and 58%, respectively. [14]

Despite the notion that estimations have an inherent margin of error, legal texts and journals have maintained that a physician’s failure to assess fetal weight during pregnancy or labor constitutes a deviation from standards of practice. [63]
