Autologous Blood Donation in Open-Heart Surgery in Cooperation with the Red Cross Blood Center / 日本心臓血管外科学会雑誌

ABSTRACT

An investigation on the efficacy of preoperative autologous blood donation in open-heart surgery was made using frozen red blood cells and MAP red blood cells in cooperation with the Red Cross Blood Center. In 109 cases which received the donation, the rate of cases which received no homologous blood transfusion was 93.6% (35.3% in the cases without donation). Even in the cases of redo operation or aortic surgery, in which extensive blood loss is expected, 75% of those given a donation of 1600-2000ml frozen blood required no homologous blood transfusion. The hemoglobin concentration in the cases which received blood donation for more than 4 weeks did not decrease, indicating that safe donation is feasible. The aforementioned frozen and MAP blood preparations can be preserved for a long period so that blood donation can be started even before deciding on the date of operation. Also, its usefulness is not affected by the postponement of the operation. Furthermore, there was no problem in safety with respect to transfer, treatment, and storage of the autologous blood in cooperation with the Red Cross Blood Center, suggesting that this is useful as a preoperative donation method, especially in small- and middle-scale hospitals, which have no separate blood centers. However, there were 2 cases in which aggravated symptoms were noted after blood collection. Therefore, it is important to carefully select cases for autologous blood donation in open-heart surgery and it is desirable to set up appropriate donation schedules.
