Blood transfusion

Transfusion of blood is the process of receiving whole blood or blood products into one’s systemic circulation intravenously. It may include injection of whole blood or components such as red blood cells, white blood cells, plasma, platelets or clotting factors. Blood transfusion is usually done in cases of deficiencies, to increase the oxygen saturation, during accidents or during surgery, to treat hematologic conditions such as severe anemia, leukemia, and sickle cell disease. Blood transfusion may also be associated with various complications including infections, immunological disorders such as hemolysis or incompatibilities.
