What are common signs and symptoms of a hemolytic transfusion reaction?

A hemolytic transfusion reaction occurs when the recipient's immune system targets and destroys the transfused red blood cells, typically due to incompatible blood types. The signs and symptoms reflecting this reaction often indicate a significant physiological response.

Low back pain is a classic symptom associated with hemolytic reactions and is thought to be related to the kidneys being affected, as they work to eliminate the hemolyzed red blood cells. Increased pulse and respiratory rates can signify that the body is under stress and compensating for reduced oxygen-carrying capacity due to the destruction of red blood cells. Hematuria, the presence of blood in urine, may occur as a result of kidney damage from the hemolysis process.

These symptoms are often observed alongside other systemic responses, making this cluster particularly indicative of a hemolytic transfusion reaction. Recognizing these signs is crucial in quickly identifying and managing the reaction to minimize complications for the patient.
