Internal and external anti-infective coating of central venous catheters (CVCs) may reduce the rate of catheter colonization (CC) and bloodstream infection (BSI) . Our objective was to evaluate the efficacy of a protective nonleaching polyhexanide coating on the rate of CC and BSI in ICU settings.
A prospective, randomized, controlled, double-blind clinical trial was performed on multidisciplinary ICUs of two university hospitals in the Czech Republic between 2005 and 2010. A total of 680 patients were randomized to receive either coated CVC (Certofix® protect; B. Braun Melsungen AG) or standard CVC (Certofix®; B. Braun Melsungen AG). Primary objectives were the difference of the incidence of both CC and BSI between groups. Catheter colonization was defined as the growth of >1,000 colony-forming units using the sonication method.
Our results suggest that the use of external/internal polyhexanide-coated CVCs is associated with significant reduction of BSI but not with the reduction of colonization rate.
