enzymatic debridement
Chemical removal of necrotic tissue using topical enzyme preparations rather than surgical instruments.
Full Definition
Enzymatic debridement involves the application of topical enzyme preparations to selectively dissolve necrotic tissue while preserving viable tissue. Common enzymes include collagenase and papain-urea preparations. This method is particularly useful for patients who cannot tolerate surgical debridement or for wounds with mixed viable and non-viable tissue that requires selective removal. The process is slower than surgical debridement but offers greater precision in tissue preservation.
Usage
Usage note: Distinguish from 'autolytic debridement' which uses the body's own enzymes in a moist environment.
In Context
