Blood transfusion
Intravenous transference of blood products
Medical intervention
Blood transfusion is the process of transferring blood products into a person's circulationintravenously.[1] Transfusions are used for various medical conditions to replace lost components of the blood. Early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, plasma, platelets, and other clotting factors. White blood cells are transfused only in very rare circumstances, since granulocyte transfusion has limited applications. Whole blood has come back into use in the trauma setting.[2]
Red blood cells (RBC) contain hemoglobin and supply the cells of the body with oxygen. White blood cells are not commonly used during transfusions, but they are part of the immune system and also fight infections. Plasma is the "yellowish" liquid part of blood, which acts as a buffer and contains proteins and other imp

Highlights of Transfusion Medicine History
English physician William Harvey discovers the circulation of blood. Shortly afterward, the earliest known blood transfusion is attempted.
The first recorded successful blood transfusion occurs in England: Physician Richard Lower keeps dogs alive by transfusion of blood from other dogs.
Jean-Baptiste Denis in France and Richard Lower in England separately report successful transfusions from lambs to humans. Within 10 years, transfusing the blood of animals to humans becomes prohibited bygd law because of reactions.
In Philadelphia, American physician Philip Syng Physick, performs the first human blood transfusion, although he does not publish this information.
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 ledd

All this excitement came to an abrupt end when, during the winter of , Denis began transfusing the blood of a calf into a thirty-four-year-old manservant named Antoine Mauroy, who was subject to “phrensies” during which he would beat his wife, take off all his clothes, and run around Paris setting homes on fire. Denis hoped that blood from the gentle calf might serve as a kind of tranquillizer, calming the troubled Mauroy. After the first couple of infusions, Mauroy sweated, vomited, complained of lower-back pain, and pissed charcoal-black fluid—all, we now know, symptoms of a severe transfusion reaction in which the recipient’s antibodies attempt to destroy the newly introduced foreign substance. Nonetheless, he soon not only recovered but seemed to be a changed man, speaking lucidly, whistling merrily, and treating his wife with unprecedented tenderness. Unfortunately, a couple of months later, just as the third transfusion was about to get under way, he died. Suspicion fell on hi
