[Uncrossmatched type O red blood cell transfusion and cell saver autologous blood transfusion effective for intraoperative massive bleeding].

ABSTRACT

We experienced rapid and massive bleeding in a 57-year-old woman undergoing resection of ovarian tumor metastasis. One hour after the start of operation, blood loss increased due to adhesion of the tumor. The blood hemoglobin level decreased from 11.7 to 4.6 g x dl(-1). Since available matched homologous blood had been consumed, we transfused type O uncrossmatched red blood cells followed by cell saver autologous blood. For the treatment of uncontrollable hyperkalemia and metabolic acidosis, continuous hemodiafiltration was started. A total of 66 U of red blood cells, 48 U of FFP, and 40 U of platelets were transfused intraoperatively. No neurological deficit, pulmonary edema, renal failure, or hemolysis was found postoperatively.
