Intrapartum Ultrasonography for Labor Management

Abstract

The term fetal macrosomia indicates a birth weight of more than 4000 g regardless of gestational age. The group of Alexander and Himes set the limit at 4500 g by putting the acronym LGA (large for gestational age) as a terminology that indicates a birth weight higher than 90° centile for the gestational age, for which LAG can be a fetus of 3500 g born at 34 weeks. Recently the concept of IUGA (intrauterine growth acceleration) has been introduced, which indicates a growth in excess of the intrinsic potential of the fetus (Fig. 39.1) [1].
