Which dressing type BEST supports autolytic debridement?
Answer: Hydrocolloid or hydrogel dressings
Hydrocolloid and hydrogel dressings maintain a moist environment that supports the body's own enzymes in liquefying and separating necrotic tissue.
Autolytic debridement is CONTRAINDICATED in which situation?
Answer: Clinically infected wound requiring rapid debridement
Autolytic debridement is too slow for clinically infected wounds, where rapid debridement and infection control are necessary.
Which enzymatic debriding agent is currently FDA-approved for wound debridement in the United States?
Answer: Collagenase (Santyl)
Collagenase (Santyl) is the only FDA-approved enzymatic debriding agent currently available in the United States.
Collagenase (Santyl) should NOT be used concurrently with:
Answer: Silver-containing dressings or povidone-iodine
Heavy metals such as silver and antiseptics like povidone-iodine inactivate collagenase, reducing its enzymatic effectiveness.
Wet-to-dry gauze debridement is classified as which type of debridement?
Answer: Non-selective mechanical debridement
Wet-to-dry dressings are non-selective mechanical debridement because they remove both necrotic and viable tissue as the dressing dries and adheres.
Larval (maggot) therapy works primarily through which mechanism?
Answer: Secretion of proteolytic enzymes that selectively digest necrotic tissue
Medicinal maggots (Lucilia sericata larvae) secrete proteolytic enzymes that selectively digest necrotic tissue while sparing viable tissue.
