Requires a moist wound surface and normal WBC counts (no infection)
-Enzymatic debridement - -topical application of enzymes to surface of
necrotic tissue. can be used on infected and non-infected wounds with
necrotic tissue. may be used in wounds that have not responded to autolytic
debridement or in conjunction with other debridement techniques. can be
slow to establish a clean wound bed and should be discontinued after
removal of devitalized tissues in order to avoid damage; Nickle thick
application
-chemical debridement - -Using sodium hypochlorite ( Dakin's solution) and
similar agents. Typically reserved for wounds that are necrotic, infected, and
malodorous; remains controversial
