Acute hemolytic transfusion reaction (AHTR) is a potentially life-threatening complication of a blood transfusion. It occurs when the donor’s red blood cells are destroyed by the recipient’s immune system. If not treated quickly and appropriately, AHTR can cause serious complications, even death.
Diagnosis
AHTR is diagnosed based on a patient’s symptoms and laboratory findings. Common symptoms include fever, chills, low blood pressure, and back pain. Laboratory tests that may be used to diagnose AHTR include complete blood count (CBC) to measure the levels of red blood cells and hemoglobin, and a Coombs test to detect the presence of antibodies to the donor’s red blood cells.
Treatment
The primary goal of treatment for AHTR is to stop the destruction of red blood cells and replace lost fluids. Treatment typically includes the following:
• Stopping the transfusion: The transfusion should be stopped immediately, and the intravenous line should be removed.
• Fluid replacement: The patient should be given intravenous fluids to replace any fluid that has been lost due to hemolysis.
• Medications: Medications, such as corticosteroids, may be given to suppress the immune response and prevent further destruction of red blood cells.
• Blood transfusion: The patient may need a blood transfusion to replace lost red blood cells.
• Observation: The patient should be monitored closely for any signs of organ damage or complications.
In severe cases of AHTR, the patient may need to be admitted to the hospital for further treatment.
Prevention
AHTR can be prevented by taking steps to ensure that blood transfusions are safe and appropriate for the patient. Before a transfusion is given, the patient’s blood type should be checked to ensure compatibility with the donor’s blood. Additionally, the donor’s blood should be screened for infectious diseases, and the patient should be monitored closely during and after the transfusion.
