transfusioissa

Transfusioissa, commonly referred to as blood transfusions, are a medical procedure in which donated blood or blood components are given to a patient intravenously. This procedure is used to replace blood lost through surgery or injury, or to compensate for a lack of red blood cells, platelets, or plasma proteins. Blood for transfusion is carefully screened for infectious diseases to ensure its safety.

The most common type of transfusion involves red blood cells, which carry oxygen throughout the body. These are used to treat anemia, a condition where the body doesn't have enough healthy red blood cells. Platelet transfusions are given to patients with low platelet counts or impaired platelet function, which can prevent blood from clotting properly. Plasma transfusions provide clotting factors and other proteins to patients with bleeding disorders or severe burns.

Before a transfusion, the patient's blood is tested to determine their blood type and screen for antibodies. This is crucial for matching the donor's blood to the recipient's to prevent an adverse reaction, known as a transfusion reaction. Transfusion reactions can range from mild, such as fever or rash, to severe and life-threatening. Medical professionals closely monitor patients during and after a transfusion for any signs of complications. While generally safe, blood transfusions are a critical medical intervention used when the benefits outweigh the potential risks.
