Objectives: To characterize clinically, epidemically and microbiologically the episodes ofconfirmed bacteremia associated with intravascular catheters of patients in the pediatric intensive careunit. Study Design: An analytical, prospective study. Setting: Intensive care unit of Pediatric HospitalJosé Luis Miranda”. Period: January 2003 to December 2007. Methods: 453 patients. Rates, densityof incidence, risk factors, static’s and mortality were determined and analyzed. Results: 96 patientsdeveloped bacteremia episodes and 90 (74%) had microbiological criteria. The risk factors associate were:to have multiple catheters, permanency with the catheter more than 7 days, parenteral feeding, prolongedmechanical ventilation, previous transfusions and surgical interventions. The isolations of coagulasenegative staphylococci prevailed in 33 patients (36, 7%). The previous demurrage to the insert of thecatheter was of 4,0 ± 9,4 days for the healthy ones and 11, 6 ± 24,6 days in the sick persons (p = 0,000);the definitive demurrage was of 56,1 ± 62,4 days in the sick persons versus 24,6 ± 31,7 days in the healthyones (p = 0,000). The mortality of the second group was superior (26%). Conclusions: Multiple dependentand independent factors exist on which actions should be focused to prevent and to diminish the mortalityby bacteremias associated with catheters in children admitted in intensive care units.
