What are the indications for blood transfusions?
Indications of blood transfusion can be summed up as:
- Major Surgical Operation.
- Accidents resulting in considerable blood loss.
- Cancer patients requiring therapy.
- Women in childbirth and newborn babies in certain cases.
- Patients of hereditary disorders like Haemophilia and Thalassaemia.
- Severe burn victims.
Blood transfusions are done to replace blood lost during surgery or due to a serious injury. A transfusion also may be done if your body can't make blood properly because of an illness. During a blood transfusion, a small needle is used to insert an IV line into one of your blood vessels.
- The normal daily production of red blood cells (RBC) in a healthy adult is about 0.25 mL/kg and the average lifespan of the cells is about 120 days, whereas that of transfused RBCs is about 50–60 days and can be significantly shorter in the presence of factors reducing their survival.
- Answer: A blood transfusion may take several hours depending on what your doctor has ordered for you. Initially, it has to be cross matched and this process can take up to two (2) hours. Also, each unit of blood transfuses over 1½ to 2 hours.
- Blood is essential for good health because the body depends on a steady supply of fuel and oxygen to reach its billions of cells. Even the heart couldn't survive without blood flowing through the vessels that bring nourishment to its muscular walls.
Cancer patients may need a transfusion because of blood loss during surgery. Cancer patients also need blood to compensate for one of the side effects of the chemotherapy drugs they receive. Chemotherapy drugs affect fast-dividing normal cells as well as the cancerous cells.
- The samples may show cancer cells, proteins or other substances made by the cancer. Blood tests can also give your doctor an idea of how well your organs are functioning and if they've been affected by cancer. Examples of blood tests used to diagnose cancer include: Complete blood count (CBC).
- A person with anemia may experience symptoms and signs such as:
- Shortness of breath.
- Decreased energy.
- Underlying causes for a low white blood cell count can range from benign disorders, such as vitamin deficiencies, to more serious blood diseases, such as leukemia or lymphoma. A truly low white blood cell count also puts you at higher risk for infections — typically bacterial infections.
