Accuracy of clinical suspicion of growth restriction at term despite a normal growth ultrasound: A retrospective cohort study

Abstract

BACKGROUND: Small for gestational age (SGA) is a major determinant of poor perinatal outcome. Detecting SGA at term using ultrasound is challenging and we often plan birth based on clinical assessment. AIMS: To determine the incidence of SGA infants with birthweight <10th centile among women undergoing planned birth at term for suspected SGA despite a normal estimated fetal weight (EFW) on ultrasound at 35-37 weeks. MATERIALS AND METHODS: We performed a retrospective study including all women with a fetal growth ultrasound at ≥35 weeks reporting an EFW ≥ 10th centile (appropriate for gestational age, AGA) who subsequently had an induction of labour or caesarean birth at ≥37 weeks due to ongo..
