Insights

This pilot study found no significant differences in infant oxygenation with different feeding strategies during red blood cell (RBC) transfusions. Further research is needed to confirm these findings for transfusion-related necrotizing enterocolitis (TR-NEC) prevention.

Area of Science:

  • Neonatalogy
  • Pediatric Gastroenterology
  • Critical Care Medicine

Background:

  • Red blood cell (RBC) transfusion is linked to transfusion-related necrotizing enterocolitis (TR-NEC) in preterm infants.
  • Peri-transfusion feeding practices vary, potentially influencing outcomes.

Purpose of the Study:

  • To investigate the effect of three feeding strategies on cerebral and splanchnic oxygenation during RBC transfusion in very preterm infants.
  • To explore the relationship between feeding strategies, oxygenation, and TR-NEC incidence.

Main Methods:

  • A single-center randomized pilot trial involving infants <32 weeks' gestation requiring RBC transfusion.
  • Infants were assigned to feeds withheld, reduced by 50%, or continued during transfusion.
  • Near-infrared spectroscopy (NIRS) measured cerebral and splanchnic oxygenation (rSO2, FTOE, SCOR) pre-, during, and post-transfusion.

Main Results:

  • No statistically significant differences in cerebral or splanchnic oxygenation (rSO2, FTOE, SCOR) were observed between the three feeding groups.
  • Exploratory analysis indicated lower pre- and during-transfusion splanchnic oxygenation in infants who developed TR-NEC.
  • TR-NEC occurred in 8/45 infants (2, 1, and 5 across groups).

Conclusions:

  • This pilot study did not demonstrate significant differences in cerebral or splanchnic oxygenation based on feeding strategies during RBC transfusion.
  • Findings are hypothesis-generating and do not imply equivalence; larger trials are required for confirmation.
  • Further investigation is needed to optimize feeding practices and reduce TR-NEC risk in transfused preterm infants.
