Untoward effects of blood transfusion are not unexpected and in many cases are benign. However, some reactions cause serious morbidity and may be fatal [1]. The problem is that the initial symptoms of reactions with serious or relatively benign consequences are often similar.
Adverse reactions can occur in any blood transfusion recipient, but are more common in patients with hematologic and oncologic diseases [2,3]. They can be categorized as immunologic, infectious, chemical, and physical; some also subdivide these reactions into acute and delayed types [4].
