Insights
Withholding feeding during blood transfusions for preterm infants with anemia may reduce necrotizing enterocolitis risk. Clinical equipoise suggests local decisions on feeding practices are reasonable until more evidence is available.
Area of Science:
- Neonatal Medicine
- Pediatric Gastroenterology
- Hematology
Background:
- Anemia of prematurity is common in preterm infants.
- Blood transfusions are frequently required but carry risks.
- Transfusion-associated necrotizing enterocolitis (TANEC) is a serious complication.
Purpose of the Study:
- To evaluate the impact of feeding practices during blood transfusions on TANEC risk in preterm infants.
- To synthesize current evidence on the clinical question: 'In a preterm infant with anemia of prematurity, do feeding practices during blood transfusion reduce the risk of developing TANEC?'
Main Methods:
- Evidence-based review of existing literature.
- Analysis of clinical trial data (where available).
Main Results:
- Limited evidence suggests withholding enteral feeds during red blood cell transfusion may decrease TANEC risk.
- Clinical equipoise exists regarding the optimal feeding strategy.
Conclusions:
- Individual clinical units may consider withholding enteral feeds during transfusions based on current limited evidence.
- The UK-based Withholding Enteral Feeds Around Transfusion (WHEAT) trial is expected to provide definitive evidence.
- Further research using innovative study designs in neonatal care is warranted.
Abstract:
Our evidence-based review set out to answer the clinical question 'In a preterm infant (patient) with anaemia of prematurity, do feeding practices (intervention) during blood transfusion reduce the risk of developing transfusion-associated necrotising enterocolitis (outcome)'? We found limited evidence that withholding feeding during red blood cell transfusion in preterm infants may reduce the risk of development of transfusion-associated necrotising enterocolitis. As clinical equipoise seemingly exists, it seems reasonable for individual units to make their own decisions regarding whether to withhold or continue enteral feeds during red blood cell transfusion until further evidence is available. The UK-based Withholding Enteral Feeds Around Transfusion (WHEAT) trial, a nation-wide multi-centre 'opt-out' randomised controlled study, hopefully will definitively answer our clinical question. Further research in other areas of neonatal care, using this innovative study design, is needed and it is exciting to see such a study underway.
