You are being invited as a volunteer to participate in the study "Dressing impregnated with chlorhexidine and vancomycin for the prophylaxis of central venous catheter-related infections." The objective is to evaluate the incidence of bloodstream infection related to the catheter in ICU patients with central venous catheters (CVC), using dressings impregnated or not with chlorhexidine/vancomycin. We believe this study is important as it aims to evaluate a new dressing method intended to reduce bloodstream-related infections.

IInclusion criteria included: age over 18 years, admitted to the ICU, need for a CVC placed in the ICU by the trained team, use of the CVC for a period exceeding 72 hours, and intact skin in the area of contact with the dressing. CVC inserted outside the ICU and need for two CVCs in the same patient simultaneously were exclusion criteria. A subsequent CVC could not be randomized. Other infections were not excluded during the evaluation. Only short-term CVC were evaluated (long-term and hemodialysis were excluded).
