Plasmatransfusjoner

Plasmatransfusjoner, also known as plasma transfusions, involve the administration of human plasma to a recipient. Plasma is the liquid component of blood, consisting mainly of water, salts, antibodies, and proteins, including clotting factors. This procedure is primarily used to treat or prevent bleeding in patients with clotting factor deficiencies, such as hemophilia or disseminated intravascular coagulation (DIC). It can also be employed to replace lost blood volume in cases of severe trauma or burns, or to provide antibodies to combat certain infections.

The process begins with obtaining plasma from a donor, which is then screened for infectious diseases. The plasma can be used fresh or frozen. Before administration, it is cross-matched with the recipient's blood to ensure compatibility, although a full cross-match is not always necessary for plasma. The plasma is then infused intravenously into the recipient. While generally safe, potential risks include allergic reactions, fluid overload, and the transmission of infections, although donor screening has significantly reduced this risk. Plasmatransfusjoner play a critical role in managing various medical conditions where plasma components are deficient or lost.
