Sickle cell disease is a genetic hemoglobinopathy characterised by vasoocclusive events and chronic haemolytic anaemia. Transfusion is a major therapeutic modality in this disease by decreasing the percentage of abnormal haemoglobin Hb S while increasing oxygen carrying capacity. Simple transfusions or exchange transfusions can be indicated occasionally or on a chronic transfusion program. Iron overload, vascular access and alloimmunization to erythrocyte antigens are causes of great concern in these young patients.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
