Changes to hepatic tissue oxygenation, abdominal perfusion and its association with enteral feeding with liberal transfusion threshold in anaemic preterm infants: A prospective cohort study.

In mildly anaemic preterm infants, when allowing a liberal Hb threshold-based trigger for PRBC transfusion, changes in abdominal arterial circulation were present, but not in hepatic tissue oxygenation. Withholding enteral feeds during PRBC transfusion had no impact on hepatic tissue oxygenation or mesenteric flows.
