James Blundell, a British obstetrician, performed the first successful transfusion of human Blood to a patient for the treatment of postpartum hemorrhage. Using the patient's husband as a donor, he extracted a small amount of Blood from the husband's arm and, using a syringe, he successfully transfused the wife. Between 1825 and 1830, he performed ten documented transfusions, five of which proved beneficial to his patients, and published these results. He also devised various instruments for performing Blood transfusions.
In London England, Samuel Armstrong Lane, aided by consultant Dr. Blundell, performed the first successful whole Blood transfusion to treat hemophilia.
