Gastric emptying of different meal volumes of identical composition in preterm infants: a time series analysis

Background Preterm infants’ meals typically progress to higher volumes over time. Knowledge of gastric emptying (GE) responses to differing meal volumes may inform enteral feeding management. We examined the effect of meal volume and composition on preterm GE. Methods Forty infants were studied at 3...

Summary:Background Preterm infants’ meals typically progress to higher volumes over time. Knowledge of gastric emptying (GE) responses to differing meal volumes may inform enteral feeding management. We examined the effect of meal volume and composition on preterm GE. Methods Forty infants were studied at 33.3±1.4 (29.7–35.6) weeks postmenstrual age when fully enteral fed (target 150 ml/kg/day). Intraindividual comparisons of GE were made for paired meals of 100% and 75% prescribed volume and identical composition of mother’s own milk ( n =21) and pasteurized donor human milk ( n =19). Serial stomach ultrasound images were used to calculate gastric residual volumes (GRVs) and remaining meal proportions (% meal). Results GE was faster in the early postprandial period and slowed over time ( P
