For wounds with necrotic debris, which dressing is typically recommended, and when should it be removed?

• A. Wet-to-dry dressings; remove after 24 hours
• B. Dry gauze only; remove after 72 hours
• C. Moisturizing ointment with no dressing
• D. Wet-to-dry dressings; remove after 48 hours

Answer: (D)

Wounds with necrotic debris benefit from mechanical debridement to remove nonviable tissue and create a cleaner wound bed for healing. Wet-to-dry dressings accomplish this because as the dressing dries, it adheres to the dead tissue; when you remove it, it pulls away the necrotic material and helps clear debris. Leaving the dressing in place about 48 hours allows it to dry and debride effectively while balancing the risk of maceration or pain, after which you reassess and repeat as needed.

Dry gauze alone wouldn’t provide the debridement effect needed for necrotic debris, and removing dressings after 72 hours would increase the chance of trapping bacteria and delaying healing. Moisturizing ointment with no dressing wouldn’t address the necrotic tissue at all.
