How to Change a Silver Foam Dressing at Home After a DFU Visit

Between clinic visits, keeping your diabetic foot ulcer dressing clean, dry, and changed on schedule is one of the biggest things you can do to protect healing. Use this routine every 48 hours, or sooner if the dressing is soaked, loose, or soiled.

Before you start

• Wash your hands with soap and water for 20 seconds.
• Gather supplies: hypochlorous acid solution, new silver hydrofiber foam dressing, clean gauze, tape or wrap, a trash bag, and your pH-balanced moisturizer.
• Sit somewhere with good light so you can actually see the wound.

Step-by-step dressing change

1. Remove the old dressing gently. Loosen the edges first. If it sticks, moisten it with the hypochlorous acid solution rather than pulling.
2. Look at the wound. Note the color of the wound bed, any new drainage, odor, or spreading redness on the surrounding skin.
3. Cleanse the ulcer. Spray or soak the wound with hypochlorous acid solution and let it sit for the time your clinician told you (usually 1–2 minutes). Pat the surrounding skin dry with clean gauze.
4. Apply the new silver hydrofiber foam. Place it directly over the wound bed so it fully covers the opening with a small margin of intact skin around it.
5. Protect the surrounding skin. Apply a thin layer of pH-balanced moisturizer to the skin around — not on — the wound.
6. Secure the dressing with tape or wrap so it stays put inside the cast walker without cutting off circulation.
7. Put the cast walker back on before you stand up. Every step without it adds pressure to the ulcer.

When to call your care team instead of changing at home

Stop and call if you see spreading redness, new swelling, foul odor, thick or colored drainage, new pain, or if you develop a fever. These can be early signs of infection.
