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. Through this line, you receive healthy blood. The procedure usually takes 1 to 4 hours, depending on how much blood you need. Blood transfusions are very common. Each year, almost 5 million Americans need a blood transfusion.
During the Procedure. The blood transfusion procedure begins when an intravenous (IV) line is placed onto the patientâs body. It is through the IV that the patient will begin to receive the new blood. Depending on the amount of blood, a simple blood transfusion can take between 1-4 hours. After the Procedure. Following the completion of the blood transfusion, the patientâs vital signs are checked and the IV is removed.
