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.
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. There is evidence that ...
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
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 ...
Necrotic tissue, slough, eschar: Wounds may be covered with a layer of dead tissue which may appear cream/yellow in color (slough) or as a black, hardened tissue . Removing this tissue is critical for properly evaluating both the depth of a wound and quality of the wound bed, and promotes wound healing. Wound edges: May provide clues to cause ...
This excess collateral damage inhibits the healing process. Thus, untreated necrosis results in a build-up of decomposing dead tissue and cell debris at or near the site of the cell death. A classic example is gangrene. For this reason, it is often necessary to remove necrotic tissue surgically, a procedure known as debridement. [citation needed]
A greater amount of exudate and necrotic tissue in a wound increases likelihood of infection by serving as a medium for bacterial growth away from the host's defenses. [14] Since bacteria thrive on dead tissue, wounds are often surgically debrided to remove the devitalized tissue. [38]
It also plays an additional role in autolytic debridement (removal of dead tissue) which is less painful when compared to manual wound debridement inside the operating theater. It is highly elastic and flexible, thus is closely adhered to the skin. As the dressing is transparent, wound inspection is possible without removing the dressing.
