Successful Case of Double Valve Replacement Surgery Using Autologous Blood Transfusion: A Patient's Autonomy Preserved with Excellent Clinical Outcome

BACKGROUND A blood cell saver, or autotransfusion system, is used to collect, wash, and return autologous blood collected from the surgical patient. This report describes a 55-year-old man who underwent combined mitral and aortic valve replacement surgery with cardiopulmonary bypass and had a successful outcome following intraoperative and postoperative autologous blood transfusion using a blood cell saver. CASE REPORT The patient did not accept blood transfusion for reasons of religious conscience and was in a critical condition, receiving palliative care. He needed combined mitral and aortic valve replacement surgery. The surgery was conducted using a cell saver (Sorin Xtra Autotransfusion System) in the intraoperative and postoperative periods for 24 h, to resolve this challenging case, from a technical and ethical point of view. The volume of red blood cells recovered intraoperatively was 1430 mL, with a hematocrit level of 40%, and 690 mL, with a hematocrit of 35%, in the postoperative period. Therefore, a significant volume of autologous blood was recovered. The autologous blood transfusion resulted in an excellent clinical outcome for the patient, who was discharged on the ninth postoperative day. CONCLUSIONS We can conclude that the use of a blood cell saver in cardiac surgery, in both intra- and postoperative periods, resulted in the maintenance of adequate hemoglobin and hematocrit levels, no infection postoperatively, and rapid and complete recovery of the patient. Thus, the use of the blood cell saver guaranteed the individual's autonomy to refuse blood products safely, with good clinical results, and without dependence on allogeneic blood transfusions.
