Name the four main wound debridement methods and a typical indication for each.

• A. Surgical/sharp debridement — autolytic debridement for moist necrotic tissue.
• B. Autolytic debridement — manual scrubbing with wet-to-dry dressings.
• C. Mechanical debridement — enzymatic breakdown of nonviable tissue.
• D. Enzymatic debridement (collagenase) — selective debridement.

Answer: (C)

Four main wound debridement methods are surgical or sharp, autolytic, mechanical, and enzymatic. Surgical or sharp debridement uses a scalpel or scissors to quickly remove nonviable tissue and reduce bioburden; it’s the fastest way to clear extensive necrosis and prepare a wound for closure or grafting, especially when infection or rapid healing is a priority. Autolytic debridement relies on moist dressings to create a conducive environment for the body's own enzymes to liquefy and remove dead tissue; it’s gentle and highly selective, best suited for non-infected, stable wounds or patients who cannot tolerate more invasive methods, though it works slowly. Mechanical debridement involves physical removal of dead tissue through actions like wet-to-dry dressings, wound irrigation, or hydrotherapy; it can be nonselective and may remove healthy tissue, so it’s used when there is loose necrotic tissue or when other options aren’t feasible and quicker debridement is needed. Enzymatic debridement uses topical enzymes, such as collagenase or papain-urea, to digest necrotic tissue; it’s selective and useful when sharp debridement isn’t possible or desirable, though it tends to work more slowly, and collagenase is generally avoided in infected wounds.
