To test the efficacy of the ARROWgard (Arrow International Inc, Reading, Pa) central venous catheter (CVC) coated with silver sulfadiazine and chlorhexidine (A-CVC) in the prevention of CVC-related infections.


Prospective, randomized trial.


A tertiary care medical center.


Two hundred eighty-two patients who required CVC placement were evaluated in this study. Patients were prospectively randomized to receive either a standard CVC (S-CVC) or the A-CVC. Only fresh-stick double- and triple-lumen catheters were studied.


Patients were evaluated for catheter site inflammation, catheter site colonization, local catheter-related infection, and catheter-related septicemia.


The 2 groups were matched for age, percentage in the intensive care unit, percentage receiving total parenteral nutrition, percentage with triple-lumen catheters, and duration of catheterization. Rates of catheter site inflammation in the 2 groups were similar (12% vs 10%, S-CVC group and A-CVC group, respectively). The A-CVC was associated with a significantly decreased catheter site colonization rate (49% vs 28%; 43% reduction; P<.001) and local catheter-related infection rate (22.4% vs 5.8%; 74% reduction; P<.001). Rates of catheter-related septicemia were reduced by 41% in the A-CVC group (6.4% vs 3.8%, S-CVC group and A-CVC group, respectively), but this was not statistically significant.


Despite a marked decrease in catheter site colonization and catheter-related infection rates, the A-CVC did not significantly reduce the incidence of catheter-related septicemia. This may be due to a greater pathogenic dependence on catheter hub contamination rather than catheter site colonization or local catheter-related infection, or the relatively short (5.2 days) duration of catheterization in this study.
