Emerging evidence on the safety of enteral feeding during PRBC transfusion in preterm infants

Area of Science:

• Neonatal Medicine
• Pediatric Gastroenterology
• Clinical Nutrition

Background:

• Premature infants often require packed red blood cell (PRBC) transfusions due to anemia.
• Current clinical practice frequently involves withholding enteral feeds during PRBC transfusions.
• The evidence supporting this practice is limited and potentially outdated.

Purpose of the Study:

• To evaluate the necessity and potential harms of withholding enteral nutrition during PRBC transfusions in preterm infants.
• To examine the physiological capacity of the preterm gut to tolerate feeding during transfusion.
• To inform evidence-based guidelines for nutritional management during transfusion in vulnerable neonates.

Main Methods:

• Review of existing literature on PRBC transfusion practices in neonates.
• Analysis of emerging physiological data regarding preterm gut function and autoregulation.
• Exploration of potential morbidities associated with unnecessary fasting.

Main Results:

• High-quality evidence supporting the routine withholding of feeds during PRBC transfusions is lacking.
• Physiological data suggest the preterm gut has adequate autoregulatory capacity to tolerate feeding during transfusion.
• Unintended morbidities may arise from prolonged or unnecessary fasting periods.

Conclusions:

• The practice of withholding feeds during PRBC transfusion requires re-evaluation due to insufficient evidence.
• Allowing feeding during transfusion may be physiologically feasible and beneficial for preterm infants.
• Future research should focus on safety profiles, anemia severity, and feeding types to optimize nutritional support and minimize fasting in extremely low birth weight infants.
