Introduction
Fever above 38°C generally contraindicates blood transfusion, as it may mask transfusion reactions and complicate clinical assessment. Additionally, certain blood components may be consumed during infusion if body temperature is too high. Alcohol should be avoided before transfusion, although light food intake is acceptable to prevent an empty stomach. After transfusion, adequate rest is recommended and strenuous activities should be avoided.
Fever of 38°C or higher generally contraindicates blood transfusion, as it may mask transfusion reactions and complicate clinical assessment.
Patients should typically maintain a normal body temperature before transfusion to allow timely observation of any symptoms that may arise afterward, enabling prompt treatment. If fever is present with a temperature above 38°C, it may be difficult to distinguish between bleeding-related symptoms and adverse transfusion reactions, complicating monitoring. Additionally, fever may worsen the patient's condition. When these factors are mixed, transfusion reactions can severely impact health. Moreover, if body temperature is too high, certain blood components may be consumed during infusion, reducing therapeutic effectiveness. Therefore, blood transfusion is generally not recommended when a patient has a fever of 38°C. Close monitoring of the patient’s temperature and overall condition is essential during transfusion; if adverse reactions occur, the transfusion should be stopped immediately and appropriate treatment initiated based on symptoms.
In addition, alcohol consumption should be avoided before transfusion. Patients may eat some food to avoid an empty stomach. After transfusion, adequate rest is important and strenuous activity should be avoided. Early detection and early intervention are crucial.
