During CVAD dressing changes, which cleansing agent is specified?

• A. Chlorhexidine cleansing agent.
• B. Isopropyl alcohol.
• C. Hydrogen peroxide.
• D. Saline solution.

Answer: (A)

During CVAD dressing changes, skin antisepsis is key to preventing catheter-related infections. The cleansing agent specified is chlorhexidine-based antiseptic, usually chlorhexidine gluconate in alcohol. This combination acts quickly to kill a broad range of microbes and, importantly, leaves persistent antimicrobial activity on the skin. That persistent effect reduces microbial colonization around the catheter entry site and lowers infection risk more than other agents. Using isopropyl alcohol alone cleans but doesn’t provide lasting protection; hydrogen peroxide isn’t used routinely for this antisepsis due to variable efficacy and potential irritation; saline is for flushing, not disinfection. So, chlorhexidine cleansing agent is the best choice for CVAD dressing changes.
