What are the effects of expired blood unit transfused?

Transfusing an expired blood unit can have serious consequences for the patient. The primary risk is hemolysis, which is the destruction of red blood cells. Expired blood contains a higher level of free hemoglobin, which is toxic to the kidneys and can cause kidney damage. Additionally, expired blood may contain bacteria or other pathogens that can cause infections. The following are some of the potential effects of transfusing an expired blood unit:

* Hemolysis: Hemolysis is the destruction of red blood cells, which can lead to anemia. Anemia can cause fatigue, shortness of breath, and dizziness. In severe cases, hemolysis can be fatal.

* Kidney damage: Free hemoglobin can damage the kidneys, leading to kidney failure. Kidney failure can be a life-threatening condition that requires dialysis or a kidney transplant.

* Infection: Expired blood may contain bacteria or other pathogens that can cause infections. These infections can be serious and even fatal.

* Allergic reactions: Expired blood may also contain allergens that can cause allergic reactions in the patient. Allergic reactions can range from mild to severe, and in severe cases, can be fatal.

If you have received an expired blood unit, it is important to seek medical attention immediately.
