Patients with sickle cell disease may benefit from blood transfusion therapy. However, transfusion may cause more harm than good due to complications such as iron overload, infection or alloimmunization.
General guidelines:
(1) acute simple transfusion: when increased oxygen carrying capacity is desired but no significant decrease in hemoglobin S concentration is required.
(2) chronic simple transfusion: limited by long term complications to a few conditions
(3) exchange transfusions: management or prevention of organ or life threatening events.
