Nutritional Practice-Related Alteration of Mesenteric Tissue Oxygenation in Fully Enteral-Fed Very and Extremely Preterm Neonates

Objective: The role of full enteral feeding (FEF) methods in preterm infants who are at risk for inadequate regulatory mechanisms supporting nutritional requirements for intestinal oxygen supplies is not well understood. In this study, we aimed to determine how the FEF method affects mesenteric tissue oxygenation parameters in fully enterally fed very preterm neonates. We also assessed whether the changes in mesenteric tissue oxygenation during and after feeding in these infants are influenced by hemodynamic and feeding-associated parameters.
