What is a potential risk associated with the rapid infusion of packed red blood cells?

• A. Increased risk of hemolytic reaction.
• B. Decreased oxygen carrying capacity.
• C. Sepsis from bacterial contamination.
• D. Increased risk of transfusion-related acute lung injury (TRALI).

Answer: (D)

The potential risk associated with the rapid infusion of packed red blood cells is an increased risk of transfusion-related acute lung injury (TRALI). This is a serious complication that can occur after a blood transfusion, particularly with the administration of plasma-containing blood products such as red blood cells. TRALI is characterized by acute respiratory distress and pulmonary edema, which can arise from the activation of the recipient’s immune system against donor leukocytes present in the blood components.

When packed red blood cells are infused quickly, there is a greater chance of introducing a significant volume of plasma along with the cells, which may contain antibodies that trigger an immune response. This immune response can cause the release of inflammatory mediators leading to increased vascular permeability in the lungs, hence causing fluid accumulation and respiratory distress.

Understanding TRALI is crucial for healthcare providers, as prompt recognition and supportive care can significantly affect patient outcomes. While other risks associated with blood transfusions exist, such as hemolytic reactions or sepsis from contamination, the specific association of rapid infusion with TRALI underscores the importance of careful monitoring and appropriate transfusion protocols.
