Red blood cell transfusions

Definition

Red blood cell transfusions involve the administration of red blood cells to a patient in order to treat anemia or significant blood loss. They are critical for maintaining adequate oxygen delivery to tissues and organs when endogenous production is insufficient.

5 Must Know Facts For Your Next Test

1. Red blood cell transfusions are often indicated for patients with chronic anemia, including those caused by nutritional deficiencies such as iron, vitamin B12, or folate.
2. Patients with chronic hematologic illnesses like sickle cell disease or thalassemia may require regular red blood cell transfusions to manage their condition.
3. Transfusions can improve symptoms such as fatigue, shortness of breath, and dizziness by increasing the oxygen-carrying capacity of the blood.
4. Proper crossmatching and screening for infectious diseases are essential steps before administering a red blood cell transfusion to ensure compatibility and safety.
5. Possible complications of transfusions include allergic reactions, febrile non-hemolytic reactions, and in rare cases, hemolytic reactions or infections.
