Febrile non-hemolytic transfusion reaction (FNHTR) is the most common type of transfusion reaction. It is a benign occurrence with symptoms that include fever but not directly related with hemolysis. [1] It is caused by cytokine release from leukocytes within the donor product as a consequence of white blood cell breakdown.
However, this type of transfusion reaction is less severe when compared to acute haemolytic transfusion reaction. [36] Febrile nonhemolytic reactions are, along with allergic transfusion reactions, the most common type of blood transfusion reaction and occur because of the release of inflammatory chemical signals released by white blood cells ...
Hemolytic transfusion reactions are a possible complication from red blood cell transfusions. Hemolysis refers to the lysis (rupture) of red blood cells, and the resulting leakage of their contents. Hemolytic reactions may be immune or non-immune mediated. Immune-mediated hemolytic reactions, such as DHTR, represent a type of alloimmunity.
An acute hemolytic transfusion reaction (AHTR), also called immediate hemolytic transfusion reaction, is a life-threatening reaction to receiving a blood transfusion. AHTRs occur within 24 hours of the transfusion and can be triggered by a few milliliters of blood. The reaction is triggered by host antibodies destroying donor red blood cells.
Adverse effects reported with the usage of cryoprecipitate include hemolytic transfusion reactions, febrile non-hemolytic reactions, allergic reactions (ranging from urticaria to anaphylaxis), septic reactions, transfusion related acute lung injury, circulatory overload, transfusion-associated graft-versus-host disease, and post-transfusion purpura.
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
In transfusion medicine, transfusion-associated circulatory overload (aka TACO) is a transfusion reaction (an adverse effect of blood transfusion) resulting in signs or symptoms of excess fluid in the circulatory system (hypervolemia) within 12 hours after transfusion. [2]
