Insights
Red blood cell (RBC) transfusions are vital for neonates but carry uncertain risks. Improving RBC preparation and transfusion practices can enhance safety and outcomes for premature and term infants.
Area of Science:
- Neonatal Medicine
- Transfusion Medicine
- Pediatric Hematology
Background:
- Red blood cell (RBC) transfusion is a critical intervention for anemic neonates and infants, especially premature infants and those undergoing surgery.
- Current evidence-based guidelines for RBC transfusion indications and understanding of adverse effects (e.g., necrotizing enterocolitis, neurodevelopmental impairment) in neonates are limited.
- Existing blood banking practices are often extrapolated from adult and older pediatric populations, highlighting a need for neonatal-specific approaches.
Purpose of the Study:
- To review key opportunities for improving RBC preparation and transfusion practices in neonates and infants.
- To address current knowledge gaps concerning the safety and efficacy of RBC transfusions in preterm and term neonates.
- To explore how emerging technologies and neonatal-specific data can optimize transfusion strategies.
Main Methods:
- This review synthesizes current literature and highlights areas for future research in neonatal transfusion medicine.
- Focuses on identifying practical, addressable knowledge gaps to enhance RBC transfusion safety and efficacy.
- Emphasizes the potential of new technologies, biomarker discovery, and donor-recipient-linked cohort studies.
Main Results:
- Uncertainty persists regarding optimal RBC transfusion triggers and associated risks in neonates.
- Neonatal-specific RBC preparation and transfusion protocols are needed, differing from adult/pediatric standards.
- Emerging technologies and data can personalize transfusion needs, potentially reducing resource use and costs.
Conclusions:
- Significant opportunities exist to refine RBC transfusion practices for neonates, improving outcomes and safety.
- Developing neonatal-specific approaches in RBC preparation and transfusion is crucial for this vulnerable population.
- Further research, particularly large cohort studies, is essential to balance transfusion risks and benefits in neonates.
Abstract:
Red blood cell (RBC) transfusion is a common and lifesaving therapy for anemic neonates and infants, particularly among those born prematurely or undergoing surgery. However, evidence-based indications for when to administer RBCs and adverse effects of RBC transfusion on important outcomes including necrotizing enterocolitis, survival, and long-term neurodevelopmental impairment remain uncertain. In addition, blood-banking practices for preterm and term neonates and infants have been largely developed using studies from older children and adults. Use of and refinements in emerging technologies and advances in biomarker discovery and neonatal-specific RBC transfusion databases may allow clinicians to better define and tailor RBC transfusion needs and practices to individual neonates. Decreasing the need for RBC transfusion and developing neonatal-specific approaches in the preparation of donor RBCs have potential for reducing resource utilization and cost, improving outcomes, and assuring blood safety. Finally, large donor-recipient-linked cohort studies can provide data to better understand the balance of the risks and benefits of RBC transfusion in neonates. These studies may also guide the translation of new research into best practices that can rapidly be integrated into routine care. This review highlights key opportunities in transfusion medicine and neonatology for improving the preparation and transfusion of RBCs into neonates and infants. We focus on timely, currently addressable knowledge gaps that can increase the safety and efficacy of preterm and term neonatal and infant RBC transfusion practices.
