First successful human blood transfusion performed, and the results are published.

Date: 1818

MED
RSCH

"James Blundell, a British obstetrician, performs 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 extracts approximately four ounces of blood from the husband's arm and, using a syringe, successfully transfuses the wife. Between 1825 and 1830, he performs 10 transfusions, five of which prove beneficial to his patients, and publishes these results" (AABB). Adverse reactions are common in many early blood transfusions.
