[First French transfusions (1667-1668)]

The pioneers of blood transfusion first appeared in the 17th century, mainly in France and England, through animal experimentation, followed by some attempts in the healthy or sick. In France, the names of Dom Robert and Jean-Baptiste Denis belong to the beginning of the adventure of transfusion. Transfusions were then made with a total lack of knowledge of immunological danger. Following the death of a transfused patient, a death most likely related to acute intravascular hemolysis, the practice of transfusion was prohibited, on both sides of the Channel, by decision of Parliament.
