A 6x6 inch sacral pressure ulcer with necrotic tissue and moderate serous drainage but no infection should be debrided by which method?

• A. Wet-to-dry dressings with Betadine
• B. Wet-to-dry dressings with normal saline BID
• C. Daily vigorous scrubbing
• D. Whirlpool jet agitation

Answer: (B)

The key idea is removing dead tissue to create a clean wound bed that can heal. When a sacral pressure ulcer has necrotic tissue but no infection, a mechanical debridement approach with wet-to-dry dressings using normal saline is appropriate. The saline-moistened gauze helps loosen and pick up necrotic tissue as it dries and is removed, providing gradual debridement without introducing cytotoxic agents. Using normal saline keeps the wound moist and clean during this process, while antiseptics like Betadine can damage healthy cells and slow healing. Aggressive scrubbing or whirlpool jet agitation can traumatize the wound and increase pain or maceration, and they’re not ideal for a non-infected necrotic wound. Changing the dressings twice daily supports ongoing debridement and wound cleanliness.
