Real blood loss during hepatic resection was evaluated in 17 patients by the following equation: Real blood loss during surgery= (hematocrict value of blood taken by suction during surgery/hematocrit value in the preoperative blood examination)×estimated blood loss during surgery. Eleven of the 17 patients had associated liver cirrhosis. Mean duration of the operation and weight of the resected liver were 290 minutes and 357 g, respectively. The mean estimated blood loss during surgery was 1480 ml, and the mean hematocrit value of the blood suctioned during surgery was 23% (14-28%), which was 60% of that of the preoperative blood specimens. We concluded that the real blood loss during hepatic resection was about 60% of the estimated blood loss. Two units of red blood cells per patients were given perioperatively, and five of the 17 patients received no blood transfusion. No plasma transfusion was required in any patients. Neither liver failure nor disseminated intravascular coagulation was encountered in these patients, and the postoperative clinical course was uneventful. To date, none of the patients have post-transfusion hepatitis.
