What are blood components?
Blood has the following components and each one takes care of specific needs. * Red blood cells, Plasma and platelets. * Red blood cells – are administered to replenish blood loss- usually used by trauma and surgery patients. * Fresh frozen plasma – the liquid part of the blood, is administered to patients with liver problems, burn cases etc. * Platelets – helps in clotting when cuts or other open wounds occur. Leukemia and transplant patients, often need platelet transfusions.
• Many cellular and protein components of blood can be separated from each other. Each blood component can then be used to replace a specific blood deficiency. Components are prepared from fresh blood. The whole blood pack is spun in a refrigerated centrifuge. • RED CELL CONCENTRATES are the most widely used blood components. Most patients requiring transfusions are in need of the oxygen-carrying capacity of the red cells. Of these a few require whole blood, but most are best treated by using only red cells for treatment of anaemia and chronic blood diseases. • PLASMA is separated by spinning in a refrigerated centrifuge. It is used for treatment of some coagulation disorders. • PLATELET CONCENTRATES are used to control bleeding due to platelet deficiency. These may be caused by a disease e.g. Leukaemia or may follow severe haemorrhage. Platelet concentrates can be stored for up to 5 days. • CRYOPRECIPITATE is widely used for treatment of haemophilia A, the most common inherited bleedi
