vörösvértesttranszfúzió

Vörösvértesttranszfúzió, also known as red blood cell transfusion, is a medical procedure in which red blood cells are transferred from one person to another. This therapy is primarily used to treat anemia, a condition characterized by a deficiency of red blood cells or hemoglobin. Red blood cells are responsible for carrying oxygen from the lungs to the body's tissues, and when their count is low, various organs may not receive sufficient oxygen, leading to symptoms like fatigue, weakness, and shortness of breath.

The decision to perform a red blood cell transfusion is based on a patient's clinical condition and laboratory findings, such as their hemoglobin levels. Transfusions are typically administered in a hospital setting under the supervision of medical professionals. Before the transfusion, the patient's blood is cross-matched with the donor's blood to ensure compatibility and prevent a potentially dangerous immune reaction.

Common reasons for red blood cell transfusions include chronic anemia associated with conditions like kidney disease or cancer, acute blood loss due to trauma or surgery, and certain blood disorders such as sickle cell anemia or thalassemia. While generally safe, red blood cell transfusions carry some risks, including allergic reactions, fever, and, rarely, the transmission of infections. Strict screening of blood donors and careful monitoring of recipients help to minimize these risks. The goal of a transfusion is to restore adequate oxygen-carrying capacity to the body, thereby improving the patient's health and well-being.
