  1. 1. Ultrasound prediction of large fetuses. Epidemiological and clinical investigations

    University dissertation from Department of Obstetrics and Gynecology, Lund University

    Author : Gun Lindell; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Two-dimensional ultrasound; three-dimensional ultrasound; fetus; intrauterine growth; maternal characteristic; large-for-gestational age; antenatal calculation; Bayesian theorem; fetal weight; estimation; post-term fetus; fetal macrosomia;

    Abstract : The proportions of newborns with a birth weight (BW) >4,000 g and of macrosomic newborns (BW >4,500 g) have increased during the last two decades, parallel with an increasing maternal pre-pregnancy body mass index (BMI) and age at the time for pregnancy. Delivery of a large fetus, especially >4,500 g might cause perinatal complications for both the mother and her child. READ MORE
