Transfusion Research
Transfusion
Although practitioners experimented with transfusions as early as the 17th century, because of a malpractice suit in France, the experiments faded out of fashion.
Obstetrician James Blundell began experimenting with transfusion in the early 19th century in an effort to save his patients from death by hemorrhaging. His success encouraged him to develop various medical apparatus to assist with transfusion and to create a safer experience for both donor and patient. You can find these in the link below.
The donated blood would often be defibrinated in order to prevent the blood from creating clots for the patient, which could have deadly consequences. Other experiments attempted using milk or saline to prevent clotting, which were not as effective.
The current system of blood typing did not exist until discoveries made in 1901.
