Hemodialysis Catheter Dressing and Care Recommendations

Primary Dressing Options

The Centers for Disease Control and Prevention recommends using either sterile gauze or sterile, transparent, semi-permeable dressing to cover hemodialysis catheter exit sites, with gauze preferred if there is bleeding, oozing, or diaphoresis 1
Sterile gauze dressing is recommended as the first-line option for hemodialysis catheter sites, particularly because it reduces exit site colonization risk compared to transparent film dressings 2, 3
Sterile, transparent, semi-permeable dressings are an acceptable alternative and allow continuous visual inspection of the site 1
Both options have equivalent infection prevention efficacy according to CDC guidelines, though the evidence quality is limited 4

Replace gauze dressings every 2 days for short-term central venous catheters 1
Replace transparent dressings at least every 7 days for short-term catheters, unless soiled or loose 1
For tunneled or implanted catheters with transparent dressings, replace no more than once per week until the insertion site has healed 1, 4
Replace any dressing immediately if it becomes damp, loosened, or visibly soiled 1, 5

Apply povidone-iodine to the exit site after drying, allowing 2-3 minutes for full bacteriostatic action before it dries 2, 3
Apply topical mupirocin ointment to the catheter exit site to reduce infection risk, especially in patients with nasal Staphylococcus aureus carriage 2, 3
Do NOT use glycol-containing ointments on polyurethane catheters, as certain manufacturers contraindicate this practice 2, 3, 5

Both patient and dialysis staff must wear surgical masks during all catheter dressing changes and when catheter caps are removed 2, 3
Staff should wear clean gloves and surgical mask or face shield for all procedures accessing the bloodstream 2, 3
Use maximal sterile barrier precautions including cap, mask, sterile gown, sterile gloves for catheter insertion 1
Prepare skin with 0.5% chlorhexidine preparation with alcohol before catheter insertion and during dressing changes 1
If chlorhexidine is contraindicated, use tincture of iodine, an iodophor, or 70% alcohol as alternatives 1
Allow antiseptics to dry completely according to manufacturer recommendations before catheter placement 1
