title: [Prognostic factors in patients with massive intraoperative blood loss].
abstract: BACKGROUND
  Massive blood loss during surgery might affect the prognosis of the patient.
  
  
  METHODS
  Fifty-seven patients with massive blood loss of more than 10,000 g were the subjects of the study. We compared the postoperative complication and prognosis for the following 3 groups. Group 1 is without complications (n = 17), Group 2 is alive with complications (n = 20), and Group 3 is the death group (n = 20). The following results were obtained.
  
  
  RESULTS
  Transfusion, blood loss and urine output were prognosis decision factors. And we found out that the duration of low hemoglobin level (Hb < 7.0 g.dl-1) was closely related to the prognosis.
  
  
  CONCLUSIONS
  It will be concluded that the duration of low hemoglobin level was one of the most important parameters to determine the prognosis of patients with massive intraoperative bleeding.
