List four debridement methods and provide a primary indication for each.

• A. Surgical debridement — rapid removal of extensive necrotic tissue; Mechanical debridement — wet-to-dry or scrubbing for non-selective removal; Enzymatic debridement (collagenase) — selective necrotic tissue in non-infected wounds; Autolytic debridement — moisture-retentive dressings for non-infected wounds with necrotic tissue.
• B. Surgical debridement — removal of scar tissue; Mechanical debridement — irrigation only; Enzymatic debridement — collagenase; Autolytic debridement — heat therapy.
• C. Surgical debridement — infection control; Mechanical debridement — only shaving; Enzymatic debridement — always used; Autolytic debridement — antibiotics.
• D. Surgical debridement — chemical dissolution of tissue; Mechanical debridement — scrubbing only; Enzymatic debridement — never used; Autolytic debridement — dry dressings.

Answer: (A)

Debridement aims to remove nonviable tissue to speed healing and prepare a clean wound bed. Surgical debridement is the fastest way to clear extensive necrosis and infected tissue, making it the best choice when rapid wound bed preparation is needed due to large amounts of dead tissue or urgent infection control. Mechanical debridement uses physical action, such as wet-to-dry dressings or scrubbing, to remove debris; it’s a non-selective method that can strip healthy tissue as well, so it’s used when quick cleanup is needed and a less invasive approach is appropriate. Enzymatic debridement with collagenase relies on enzymes to digest necrotic tissue while largely sparing viable tissue, making it suitable for non-infected wounds where selective removal is preferred and surgery isn’t feasible. Autolytic debridement uses moisture-retentive dressings to create an environment that allows the body's own enzymes to liquefy necrotic tissue, offering a gentle, noninvasive option best for non-infected wounds with necrosis when slower healing is acceptable. In short, the four methods cover rapid surgical removal, non-selective mechanical cleaning, selective enzymatic digestion, and body-driven autolytic processes, each with indications centered on infection status and how quickly tissue needs to be removed.
