Direct Blood Transfusion

Direct blood transfusion is a type of interhuman blood transfusion in which blood, when transferred from one vein to another, passes through both blood vessels.

Blood is transfused according to the "conservatism - conservation" scheme in sterile conditions directly without contact of the recipient's venous blood flow with the donor's venous blood. Before and during the main transfusion, therapeutic manipulations are carried out with the recipient's circulatory system in order to maximize its blood capacity. The described methods are transfusion, that is, they are used to obtain the final result - an increase in the number of formed elements and an increase in blood hemoglobin and relate to hemocorrective therapy.

Intraoperative bone marrow transplantation for concomitant and combined myelosuppression after myelochemotherapy can be indicated for patients with stage III B–IV tumor disease (which corresponds to the results of one or more indicators: grade III anemia, thrombocytopenia less than 20x109/l, stage V granulocytopenia). IPSS myelosuppression should not be considered a contraindication for transfusion of blood components after high-dose myeloablative treatment.
