What gauge needle is recommended for a blood transfusion?

For a blood transfusion, an 18 gauge needle is recommended because it is large enough to allow for adequate flow of blood without causing hemolysis, which can occur with smaller gauge needles. The larger diameter of the 18 gauge needle minimizes the risk of damage to the red blood cells during the transfusion process, ensuring that the blood can flow freely and safely into the recipient’s circulation.

In clinical practice, using a needle that is too small can lead to complications such as increased pressure in the IV line and slower transfusion rates, both of which can negatively impact patient safety and the effectiveness of the transfusion. Therefore, the use of an 18 gauge needle strikes a balance between accessibility and safety for such procedures.
