Antiseptic measures during the insertion and manipulation of vascular catheters

Several measures related to asepsis for preventing catheter-related bloodstream infection have been proposed. The aseptic measures recommended by scientific societies include hand hygiene of the person who is inserting or manipulating the catheter; maximum sterile barrier precautions during catheter insertion; disinfection of catheter hubs; the use of needle-less connectors and injection ports; the avoidance of antibiotic ointments (except in hemodialysis catheters); change the dressing if it is soiled, loose or damp; and aseptic technique during dressing changes. Other measures only recommended by the most recently published guides (possibly due to the publication of recent studies reporting their beneficial effects) are the use of antimicrobial-impregnated dressings, changing transparent dressings every 7 days, and bathing of the patient with chlorhexidine.
