Blood Transfusion Blood transfusion: The transfer of blood or blood components from one person (the donor) into the bloodstream of another person (the recipient). Blood transfusion may be done as a lifesaving maneuver to replace blood cells or blood products lost through bleeding or due to depression of the bone marrow. Transfusion of one's own blood (autologous) is the safest method but requires advanced planning, and not all patients are eligible for it. Directed donor blood allows the patient to receive blood from known donors.

Living With Alligators in Central Florida The vast majority of alligators one may come across down here are less than 6 feet in length, but gators in the 8 ft. to 10 ft. class are not uncommon.

The State of Florida has a nuisance alligator program and will respond quickly to any concerns. The response typically involves sending a licensed trapper to locate and remove the animal.

- By Dr Ananya Mandal, MD. The first research into blood transfusion dates back to the 17th Century when British physician William Harvey fully described the circulation and properties of blood in 1628.The first blood transfusions were also attempted around this time, although these were often unsuccessful and proved fatal in humans.n 1818, British obstetrician James Blundell successfully transfused human blood to a patient who had hemorrhaged during childbirth. In 1901, Karl Landsteiner, an Austrian physician discovered the first human blood groups, which helped transfusion to become a safer practice.

However, in the case of hemochromatosis, which is now recognized as the most common genetic, or inherited, disorder, frequent bloodletting has become an essential, and life-saving procedure.

Anemia A blood transfusion is a safe, common procedure in which blood is given to you through an intravenous (IV) line in one of your blood vessels. 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.

- Definition. A blood transfusion is a routine medical procedure that can be lifesaving. During a blood transfusion, donated blood is added to your own blood. A blood transfusion may also be done to supplement various components of your blood with donated blood products. In some cases, a blood transfusion is done with blood that you've donated ahead of time before you undergo elective surgery. During a typical blood transfusion, certain parts of blood are delivered through an intravenous (IV) line that's placed in one of the veins in your arm.
