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]
Postperfusion syndrome, also known as "pumphead", is a constellation of neurocognitive impairments attributed to cardiopulmonary bypass (CPB) during cardiac surgery. Symptoms of postperfusion syndrome are subtle and include defects associated with attention, concentration, short-term memory, fine motor function, and speed of mental and motor ...
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.
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.
An allergic transfusion reaction is when a blood transfusion results in allergic reaction. It is among the most common transfusion reactions to occur. Reported rates depend on the degree of active surveillance versus passing reporting to the blood bank. [1] [2] Overall, they are estimated to complicate up to 3% of all transfusions. [3]
It is often impossible to distinguish TRALI from acute respiratory distress syndrome (ARDS). The typical presentation of TRALI is the sudden development of shortness of breath, severe hypoxemia (O 2 saturation <90% in room air), low blood pressure, and fever that develop within 6 hours after transfusion and usually resolve with supportive care within 48 to 96 hours.
Injection site reactions (ISRs) are reactions that occur at the site of injection of a drug. They may be mild or severe and may or may not require medical intervention. Some reactions may appear immediately after injection, and some may be delayed. [1] Such reactions can occur with subcutaneous, intramuscular, or intravenous administration.
Extravasation is the leakage of intravenously (IV) infused, and potentially damaging, medications into the extravascular tissue around the site of infusion. The leakage can occur through brittle veins in the elderly, through previous venipuncture access, or through direct leakage from wrongly positioned venous access devices.
