Red blood cell transfusion following burn.

Area of Science:

• Burn Medicine
• Hematology
• Transfusion Medicine

Background:

• Severe burns significantly alter hematologic parameters, commonly causing anemia in patients with >10% total body surface area (TBSA) involvement.
• Blood transfusion has been the standard treatment for anemia in burn patients, with transfusion triggers (hemoglobin/hematocrit levels) varying widely (6-8 g/dL).

Purpose of the Study:

• To analyze the current status of red blood cell (RBC) transfusions in burn patient management.
• To address new information regarding burn injury and blood transfusion practices.
• To evaluate the appropriateness of current transfusion protocols.

Main Methods:

• Review and analysis of existing transfusion literature in burn care.
• Examination of current transfusion protocols and their associated triggers.
• Assessment of factors influencing transfusion decisions.

Main Results:

• Analysis confirms a trend towards lower transfusion triggers in burn centers compared to previous years.
• Significant variation in transfusion triggers exists across different burn centers.
• Evidence suggests that a universal transfusion trigger for burn patients is not feasible.

Conclusions:

• The practice of using a universal transfusion trigger for packed red blood cells (PRBCs) in burn patients should be abandoned.
• Red blood cell transfusions must be individualized, considering patient blood volume status, blood loss acuity, and perfusion requirements.
• Focus should shift towards preventing unnecessary transfusions, minimizing blood loss, optimizing red cell production, and judiciously determining transfusion necessity.
