What IV solution is typically hung with a blood transfusion?

The best choice for an IV solution that is typically hung with a blood transfusion is 0.9% normal saline. This solution is isotonic and does not contain glucose, which is crucial during blood transfusions. Using isotonic solutions helps to maintain the integrity of red blood cells and ensures compatibility with the blood being transfused. It also helps to keep the veins open and provides a safe medium for the transfusion itself.

When considering other options, 0.45% saline is hypotonic and can cause hemolysis of red blood cells, which is not appropriate when administering a blood transfusion. 5% dextrose in water contains glucose, which can lead to cellular osmotic shifts that might adversely affect the blood components being transfused. Lactated Ringer's solution, while isotonic, contains other electrolytes that could potentially complicate blood compatibility. Therefore, the safest and most appropriate solution to use with a blood transfusion is 0.9% normal saline.
