Abstract
Neonates with absent-or-reversed umbilical artery end-diastolic flow (AREDF) are at an increased risk of feeding problems. In this retrospective study, authors evaluated the incidence of feed intolerance in 213 preterm neonates (January 2017-May 2022) with AREDF. The median (IQR) gestation and birth weight were 32 (30, 33) wk and 1120 (840, 1425) g, respectively. Of 213 neonates, 103 (48.4%; 95% CI 41.5%, 55.3%) neonates developed feed intolerance. Twelve of 213 neonates developed any stage necrotizing enterocolitis (NEC) (5.6%; 95% CI 2.9%, 9.6%) at a median age of 10 d. On multivariate regression, gestation was the only independent predictor of feed intolerance (OR 1.48; 95% CI 1.28, 1.70; for every 1 wk decrease below 36 wk).Almost 50% of preterm neonates with AREDF develop feed intolerance. Alternative feeding strategies warrant exploration to optimise nutrition in these neonates.
