Blood transfusions
Blood Transfusions
Blood transfusions (pronunciation: /blʌd trænsˈfjuːʒən/) are a common medical procedure where blood or blood components are transferred from one person (donor) to another (recipient).
Etymology
The term "transfusion" comes from the Latin transfusio, meaning "to pour over from one vessel to another". The term "blood" is derived from the Old English blod, which is akin to the Old High German bluot.
Procedure
A blood transfusion typically involves the transfusion of whole blood or components such as red blood cells, platelets, plasma, and cryoprecipitate. The blood or blood components are usually collected from a donor, tested for blood type and bloodborne diseases, and then stored until needed for a transfusion.
Indications
Blood transfusions are often used in the treatment of conditions such as anemia, hemophilia, and cancer, as well as during and after surgery.
Risks
While blood transfusions are generally safe, there are risks involved, including allergic reactions, transfusion reactions, and the transmission of infectious diseases.
