verivaihto

Verivaihto, also known as blood exchange, is a medical procedure where a portion of a patient's blood is replaced with donor blood. This is typically performed in cases of severe anemia, poisoning, or certain blood disorders. The process involves withdrawing the patient's blood and simultaneously transfusing compatible donor blood. This can be done through a central venous catheter or peripheral IV lines. Verivaihto can be partial, where a specific component of blood is exchanged, or total, where most of the patient's blood is replaced. The goal is to remove harmful substances from the bloodstream, improve oxygen-carrying capacity, or correct an imbalance in blood components. It is a complex procedure requiring careful monitoring and is usually performed in an intensive care setting. Risks can include fluid overload, electrolyte imbalances, and transfusion reactions. The decision to perform verivaihto is based on a thorough medical assessment of the patient's condition and the potential benefits versus risks.
