Etymology: L, in + directus, straight, transfundere, to pour through
the transfusion of blood to a recipient after the donor blood has been prepared with anticoagulants, defibrinating agents, or other substances, as opposed to direct transfusion of blood from donor to recipient.
indirect transfusionAn obsolete term that dignifies the practice of transfusing blood that has been collected from a donor, “typed” (ABO- and Rh-typed), screened for the presence of antibodies or infectious agents, and “processed” as deemed appropriate prior to transfusion. This is in contrast to direct transfusion, the obsolete practice of connecting via cannulae, the vascular system of donor and recipient.
