What may be done to RBCs before transfusion to a patient with cold agglutinin disease?

• A. Irradiate to prevent graft-versus-host-disease (GVHD)
• B. Wash with 0.9% percent saline
• C. Warm to 37°C with a blood warmer
• D. Transport to maintain a temperature of 20°C-24°C

Answer: (C)

Warming red blood cells (RBCs) to 37°C with a blood warmer is a critical step in managing patients with cold agglutinin disease before transfusion. In this condition, cold agglutinins can cause the patient's immune system to mistakenly attack and agglutinate RBCs at lower temperatures, potentially leading to hemolysis and other serious complications. By warming the RBCs to body temperature, the likelihood of agglutination occurring during the transfusion is minimized, thereby ensuring that the transfused blood can circulate effectively without triggering an immune response. Maintaining the blood at a cooler temperature, as mentioned in the alternative option regarding temperature transport, would exacerbate the risk of agglutination, making it an unsuitable approach for this patient population. Additionally, while irradiating blood products is a necessary intervention in preventing graft-versus-host disease for certain at-risk populations, it does not directly address the unique challenges posed by cold agglutinin disease. Washing RBCs with saline may be helpful in specific circumstances, but it does not resolve the underlying issue of cold agglutinins. Thus, warming the RBCs is the most appropriate and effective measure to ensure safe transfusion in patients with this condition.
