RESUMO

PURPOSE: The aim this study was to evaluate the clinical outcome of patients needing intra-operative blood transfusion by tissue perfusion markers. METHODS: A prospective single center cohort study. Adult patients needing blood transfusion during the intra-operative period were recruited. RESULTS: This study included 61 patients. At the time of blood transfusion the hemoglobin level was 8.4+/-1.8 g/dL. Scv02 has been the best tissue perfusion marker to determine mortality, compared with hematemetric values and other tissue perfusion markers, with a cut-off point at ROC curve equal to 80% (AUC=0.75; sensitivity=80%; specificity=65.2%). Patients who received blood transfusion and had Scv02 80% (N=32), had lower mortality rates (12.5% vs. 47.1%; p=0.008) and lower incidence of postoperative complications (58.9% vs. 72.9%; p=0.06). Blood transfusion with a Scv02 80%, are associated with worse clinical outcomes.
