Objectives

To investigate whether using the abdominal circumference growth velocity (ACGV) improves the prediction of perinatal outcome in small for gestational age (SGA) fetuses beyond that afforded by estimated fetal weight (EFW) and cerebroplacental ratio (CPR).

Methods

A cohort of 235 singleton SGA fetuses at 36‐38 weeks was examined. The AC growth velocity (ACGV), EFW and CPR centiles were calculated. The ACGV was determined from a large database of 19‐21 and 36‐38 week scans in an unselected population. Binary variables of an ACGV< 10 th, EFW< 3 rd and CPR< 5 th centiles were defined as abnormal. Composite outcomes were 1) 1+ of: umbilical artery pH< 7.10, 5 min Apgar score< 7, or neonatal unit admission, and 2) in addition, hypoglycaemia, intrapartum fetal distress, and perinatal death. Univariate and multivariate logistic regression analyses were used to analyse the relationship …
