ObjectiveThe aim of this study was to evaluate the frequency of central venous catheter-related infections in hospitalized patients receiving total parenteral nutrition. MethodsCentral venous catheters were analyzed immediately after removal due to infection, hospital discharge or thrombosis. The patients with catheter-related infection were named Group 1 and the other patients were named Group 2. ResultsEighteen patients were studied. There was no statistically significant difference in nutritional status between the two groups. A total of 28 catheters were analyzed. Sixty-eight percent of the catheters were infected: 72% of them were from Group 1 and 28% from Group 2 (asymptomatic patients). Systemic infection was diagnosed in 70% of the patients from Group 1. Positive blood culture was found in 17% of the patients from Group 2. The microorganisms found were: Staphylococcus sp. (48%), Candida sp. (21%), Enterococcus faecalis (16%), Pseudomonas aerurginosa (10%) and Proteus sp. (5%). ConclusionCentral venous catheter infection is common in hospitalized asymptomatic patients. Patients receiving total parenteral nutrition are most frequently infected with Candida sp. Therefore, the creation of barriers that block colonization in the central venous catheter is essential to decrease the morbidity and mortality among patients that depend on total parenteral nutrition.
