Blood Transfusion Therapy
Blood transfusion therapy is a medical treatment used to replace blood or specific blood components when the body does not have enough healthy blood cells or clotting factors. It may be recommended after significant blood loss, during or after major surgery, or for certain conditions affecting blood or bone marrow. Depending on the patient’s needs, doctors may use red blood cells, platelets, plasma, or other blood components.
When Is Blood Transfusion Needed?
A blood transfusion may be considered for severe anaemia, substantial blood loss, low platelet levels, or certain bleeding and clotting disorders. The treatment is individualized based on the patient’s symptoms, laboratory results, underlying condition, and clinical situation. Doctors may also consider alternatives to transfusion when appropriate.
What Happens During a Blood Transfusion?
Before treatment, a blood sample is checked to determine the patient’s blood group and compatibility with the blood component. During the procedure, the selected blood product is slowly delivered through a vein using an intravenous line. Blood pressure, pulse, temperature, and the patient’s condition are monitored before, during, and after transfusion.
Benefits and Safety
The main goal of transfusion therapy is to restore adequate oxygen-carrying capacity or support blood clotting when clinically required. Although generally safe, transfusions can occasionally cause reactions such as fever, chills, rash, allergic reactions, or other complications. Careful blood-group matching, compatibility testing, monitoring, and screening of donated blood help support patient safety.
