What type of IV catheter is generally used for blood transfusions?

Blood transfusions require a large bore catheter, typically 18 gauge or larger, to ensure that the blood can flow smoothly and quickly, minimizing the risk of hemolysis and complications during the transfusion process. A larger diameter catheter allows for the rapid infusion of the blood products, which is crucial for maintaining the patient's hemodynamic stability and ensuring the transfusion is completed efficiently. Using a smaller gauge catheter could lead to increased pressure in the blood bag, potential damage to the red blood cells, and a higher risk of transfusion reactions.

While other catheter types, like small bore or certain peripheral options, can be used for routine fluid administration or medications, blood transfusions specifically necessitate the larger bore to accommodate the viscosity of blood and facilitate a safe and effective transfusion.
