Vereülekanne

Vereülekanne, also known as blood transfusion, is a medical procedure that involves the transfer of blood or blood components from one person to another. This life-saving treatment is used to replace blood lost due to surgery, injury, or illness, or to treat conditions where the body does not produce enough healthy blood cells. The process is carefully managed to ensure compatibility between the donor's blood and the recipient's blood to prevent adverse reactions.

Blood is typically donated voluntarily and is screened for infectious diseases before being made available for transfusion. Blood is composed of several components, including red blood cells, white blood cells, platelets, and plasma. Depending on the patient's specific needs, either whole blood or specific components can be transfused. Red blood cells are used to carry oxygen, platelets help in blood clotting, and plasma contains proteins essential for various bodily functions.

Before a transfusion, the recipient's blood is cross-matched with the donor's blood to determine compatibility, specifically focusing on blood groups (ABO system) and Rh factor. This matching is crucial to avoid hemolytic transfusion reactions, where the recipient's immune system attacks the transfused red blood cells. While generally safe, potential risks associated with blood transfusions include allergic reactions, fever, and, rarely, transmission of infections. Modern screening and processing techniques have significantly minimized these risks. The decision to perform a vereülekanne is made by a healthcare professional based on a thorough assessment of the patient's medical condition and the potential benefits versus risks.
