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 .
Chemical debridement, or enzymatic debridement, is the use of prescribed enzymes that promote the removal of necrotic tissue. Mechanical debridement, is the use of debriding dressings, whirlpool or ultrasound for slough in a stable wound.
Mechanical debridement: Achieved through use of mechanical force to remove devitalized tissue (e.g. wet-to-dry dressing, pressurized wound irrigation, pulse-lavage); however, this process will remove both healthy and non-healthy tissue and is therefore considered a non-selective debridement method. Enzymatic debridement: A process of ...
Since the year 2000, the wound bed preparation concept has continued to improve. For example, the TIME acronym (Tissue management, Inflammation and infection control, Moisture balance, Epithelial (edge) advancement) has supported the transition of basic science to the bedside in order to exploit appropriate wound healing interventions [6] and has not deviated from the important tenets of ...
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.
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 ]
