What is a slough?
Slough is a soft, moist tissue composed of non-viable tissue and bacteria. It can be firmly or loosely attached and may be yellow, green, tan, or brown. In addition to forming a physical barrier to wound healing, necrotic tissue also presents an opportunity for microbial colonization and infection.
What is mechanical debridement?
Mechanical Debridement. This is the oldest form of debridement, administered by irrigation, hydrotherapy, an abrasion technique, or wet-to-dry dressings. With the wet-to-dry method, necrotic tissue that has adhered to moist wound dressings as it dries is removed along with the dressing.
What are the advantages of sharp debridement?

What is moist wound healing?
Moist wound healing inhibits the formation of a solid, impenetrable scab, which tends to block the epithelial cells from spreading horizontally through the thin layer of wound exudate and across the wound bed. The wound is then able to close quickly.
What are the two components of moist wound healing?
There are two main components to moist wound healing: 1) Do not use disinfectants over the wound and 2) Keep the wound moist. The first component, not using disinfectants, makes sense because disinfectants such as iodine, sodium hypochlorite and hydrogen peroxide are toxic to cells and should never be applied over a wound surface.
