Objetive: To determine the diagnosis value of simultaneous blood cultures. Background: The clinical criteria is not enough to establish catheter-related sepsis diagnosis and remotion or replacement of catheter are not necessary. Subjects: We evaluated 164 catheters used for total parenteral nutrition placement in 127 patients with cancer. Simultaneous blood samples -central and peripheral venous- were taken after seven at ten days of permanency or infection suspicion and compared with tip culture result. Interventions: Sensitivity, specificity and predictive values were calculated. The tip culture was the gold standar. Results: A positive centyral venous blood culture with negative peripheral blood culture result was sensitivity of 87.5% and specificity of 97.9%, a inverse result show a sensitivity of 62.5%. When both blood cultures were positive are correctly identified 83.3% of cases with a sensitivity of 93.9% and diagnostic correlation of 0.87. Conclusions: The simultaneous blood cultures are high diagnostic value.
