Debridement is the medical removal of dead, damaged, or infected tissue to improve the healing potential of the remaining healthy tissue. [ 2 ] [ 3 ] Removal may be surgical , mechanical, chemical, autolytic (self-digestion), or by maggot therapy .
It has been suggested that the presence of wound slough provides an indication of biofilm presence, [17] therefore, indicating the need to reduce the wound bioburden. Methods of effectively managing wound biofilms have been reported and include the use of topical agents, systemic antibiotics and regular episodes of debridement. [16] [18]
Debridement is defined as removal of devitalized or dead tissue, particularly necrotic tissue, eschar, or slough. Debridement is a critical aspect of wound care because devitalized tissue, particularly necrotic tissue, serves as nutrients for bacteria thereby promoting infection.
An eschar (/ ˈ ɛ s k ɑːr /; Greek: ἐσχάρᾱ, romanized: eskhara; Latin: eschara) is a slough [1] or piece of dead tissue that is cast off from the surface of the skin, particularly after a burn injury, but also seen in gangrene, ulcer, fungal infections, necrotizing spider bite wounds, tick bites associated with spotted fevers and exposure to cutaneous anthrax.
Mechanical debridement, is the use of debriding dressings, whirlpool or ultrasound for slough in a stable wound. Surgical debridement, or sharp debridement, is the fastest method, as it allows a surgeon to quickly remove dead tissue.
The dressing delivers absorption or hydration as needed over each independent wound area and aids in the natural process of autolytic debridement. It effectively removes liquefied slough and necrotic tissue, disintegrated bacterial biofilm as well as harmful exudate components, known to slow the healing process. [41]
Debride the wound – to remove slough and foreign objects from the wound to expedite healing; Reduce psychological stress – to obscure a healing wound from the view of the patient and others. Ultimately, the aim of a dressing is to promote healing of the wound by providing a sterile, breathable and moist environment that facilitates ...
Maggot therapy (also known as larval therapy) is a type of biotherapy involving the introduction of live, disinfected maggots (fly larvae) into non-healing skin and soft-tissue wounds of a human or other animal for the purpose of cleaning out the necrotic (dead) tissue within a wound (debridement), and disinfection.
