Blood transfusion of a sickle cell patient. Young male patient with sickle cell anaemia receives blood by transfusion. A blood bag (upper right) is attached to an intravenous (IV) drip fed into a vein in his hand. Sickle cell anaemia is an inherited blood disease that occurs primarily in black people. It is caused by abnormal haemoglobin in red blood cells, which makes the cells sickle-shaped. Blood transfusion may be performed to effect a temporary replacement of this haemoglobin. This may be done regularly for patients who suffer frequent and severe sickle cell crises.
