Blood transfusion

Blood transfusion is a medical procedure in which blood or its components (red blood cells, platelets, plasma) from a donor are transfused to a recipient through an intravenous infusion.

Blood transfusions are performed for a number of medical indications, such as blood loss due to injuries, operations, bleeding, as well as blood diseases (anemia, hemophilia) and oncology. Before transfusion, donor blood is carefully tested for infections and compatibility with the recipient's blood group and Rh factor to avoid immune reactions.

Blood transfusions save the lives of many patients, but carry the risk of complications such as allergic reactions, infection (eg, HIV, hepatitis), and circulatory overload. Therefore, doctors carefully weigh the indications and contraindications for this procedure for each individual patient. The safety of donor blood is ensured by modern methods of procurement, testing and storage of blood components.

Blood transfusion is a procedure in which donor blood is transfused into a recipient to replace lost or missing blood. This is one of the most common medical procedures in the world. In this article we will look at the history of the origin and development of blood transfusion, modern methods and risks associated with this procedure, as well as its significance for patients and society as a whole.

History of Blood Transfusion Blood transfusion was first performed in 1894 by Scottish physician William Hunt and his student Thomas Addison. They conducted an experiment in which blood was transfused from one dog to another, and it was successful. Since then, blood transfusions have been used to treat many diseases, including anemia, cancer, infections and injuries. However, this procedure was associated with the risk of transmitting dangerous diseases such as HIV, hepatitis C and hepatitis B virus, which led to restrictions and difficulties in its use. In addition, blood transfusions could not be carried out without government support - regulations limited the number of donors and the time of day when the intervention was carried out. Current methods to prevent transmission of infections include the use of disposable needles, blood filtration systems and vaccinations
