What are the symptoms of a transfusion reaction?
What are the symptoms of a transfusion reaction?
The most common signs and symptoms include fever, chills, urticaria (hives), and itching. Some symptoms resolve with little or no treatment. However, respiratory distress, high fever, hypotension (low blood pressure), and red urine (hemoglobinuria) can indicate a more serious reaction.
What is febrile transfusion reaction?
Febrile nonhemolytic transfusion reactions (FNHTRs) are common, occurring with 1–3% of transfusions. FNHTR manifests as fever and/or chills without hemolysis occurring in the patient during or within 4 hours of transfusion cessation. Diagnosis is made by excluding other causes of fever.
What is a post transfusion reaction?
Haemolytic post-transfusion reaction is caused by accelerated destruction of erythrocytes by immunological incompatibility between the donor and the recipient. It also occurs for non-immunological reasons: thermal, osmotic or mechanical damage and bacterial infection.
How is a transfusion reaction treated?
Transfusion reactions can vary in severity. Some symptoms can be mild and treated with acetaminophen to reduce any pain or fever. Your doctor may also prescribe intravenous fluids or medications to reduce the likelihood of kidney failure and shock.
How long after a blood transfusion can a reaction occur?
Reactions can occur between 1 day and 4 weeks after the transfusion. A person can acquire these antibodies through previous pregnancies or transfusions. These particular antibodies decrease over time to undetectable levels. Those with the antibodies have a higher chance of developing these transfusion reactions.
How long does a transfusion reaction last?
According to a 2012 article, most cases typically resolve within 48–72 hours.
How do you investigate a transfusion reaction?
When a transfusion reaction is suspected it has to be reported using the ‘Report of a Suspected Adverse Transfusion Reaction/Event’ form WRH-BT-HF-006….
- Send bottles and accompanying request form immediately to the Microbiology department in a biohazard bag.
- Dispose of sharps in the correct manner and wash hands.
When does a transfusion reaction occur?
This reaction usually occurs within six hours of receiving blood. In rare instances, bacteria may be present in the donated blood. Giving this contaminated blood to a recipient can lead to infection, shock, and death. A transfusion reaction can also occur if a person receives too much blood.
What follow up disclosure is required after transfusion reaction?
Persons known to have formed red cell alloantibodies as the result of previous transfusions or pregnancy should be informed and provided with a written report that lists the antibodies to be presented to the transfusion service if additional transfusions are required at another hospital.

What is the transfusion reaction and why does it happen?
transfusion reaction a group of clinical signs due to antibody in the recipient’s blood reacting with the transfused red blood cells when blood for transfusion is incorrectly matched, or when the recipient has an adverse reaction to some element of the donor blood.
What can cause problems in a transfusion reaction?
Acute haemolytic transfusion reaction.
Why can a transfusion reaction be fatal?
Transfusion Reactions. TRALI is now the leading cause for transfusion-related mortality. It is caused most often when donor plasma contains HLA or leukocyte (usually granulocyte) specific antibodies. Recipient leukocytes may be ‘primed’ by underlying illness to become more adherent to pulmonary alveolar epithelium.
