Transfusion reactions in neonates and pediatrics: How and why are they different?

Area of Science:

• Pediatrics
• Hematology
• Transfusion Medicine

Background:

• Neonates and children possess unique physiological and immunological characteristics distinct from adults.
• These differences render pediatric populations more vulnerable to transfusion-related complications, potentially impacting long-term development.
• Transfusion reactions in children present with varying types, frequencies, and severities compared to adults.

Purpose of the Study:

• To delineate the specific differences in transfusion reactions observed in neonatal and pediatric populations versus adults.
• To highlight the increased incidence and unique characteristics of adverse events following blood product transfusion in children.
• To underscore the need for standardized definitions and adapted transfusion protocols for pediatric patients.

Main Methods:

• Review of existing literature on pediatric transfusion reactions.
• Comparative analysis of transfusion reaction data between pediatric and adult cohorts.
• Identification of common transfusion reaction types in children, including febrile, allergic, hypotensive reactions, and volume overload.

Main Results:

• Transfusion reactions are more common in children than adults.
• Platelet transfusions are most frequently associated with adverse events in children, followed by plasma and red blood cell transfusions.
• Febrile, allergic, hypotensive reactions, and volume overload are prevalent transfusion reactions in pediatric patients.

Conclusions:

• Standardizing definitions and criteria for pediatric adverse transfusion reactions is essential for improving research and reporting.
• Modifications in blood product transfusion practices are necessary to minimize risks and enhance safety in neonates and children.
• Recognizing and addressing the distinct nature of transfusion reactions in pediatric populations is critical for optimal patient care.
