Slough is considered the by-product of the inflammatory phase of wound healing.
What does Slough mean on a wound?
Slough refers to the yellow/white material in the wound bed; it is usually wet, but can be dry. It generally has a soft texture. It can be thick and adhered to the wound bed, present as a thin coating, or patchy over the surface of the wound (Figure 3). It consists of dead cells that accumulate in the wound exudate.
What stage pressure ulcer have Slough?
Category/Stage 4: Full thickness tissue loss
Slough or eschar may be present. Often includes undermining and tunneling. The depth of a Category/Stage IV pressure ulcer varies by anatomical location.
Does yellow slough mean infection?
Slough (also necrotic tissue) is a non-viable fibrous yellow tissue (which may be pale, greenish in colour or have a washed out appearance) formed as a result of infection or damaged tissue in the wound.
What are the 4 stages of wounds?
Wound healing is classically divided into 4 stages: (A) hemostasis, (B) inflammation, (C) proliferation, and (D) remodeling. Each stage is characterized by key molecular and cellular events and is coordinated by a host of secreted factors that are recognized and released by the cells of the wounding response.
Does Stage 3 wound have Slough?
Stage 3 Pressure Injury/Ulcer
Full-thickness loss of skin, in which adipose (fat) is visible in the ulcer and granulation tissue and epibole (rolled wound edges) are often present. Slough and/or eschar may be visible.
What can I put on a Sloughy wound?
There are dressings specifically designed to promote autolytic debridement, which include thin films, honey, alginates, hydrocolloids, and PMDs. Hydrogels and hydrocolloids are additional dressing choices that may be effective in removing slough. Figure 4.
Can Stage 2 wounds have Slough?
Stage II ulcers are pink, partial, and may be painful. If any yellow tissue (slough) is noted in the wound bed, no matter how minute, the ulcer cannot be a Stage II. Once there is visible slough in the wound bed, the ulcer is at least a Stage III or greater.
Is there slough in a Stage 2 pressure ulcer?
Stage 2: Partial thickness loss of dermis presenting as a shallow open ulcer with a red pink wound bed, without slough. May also present as an intact or open/ruptured serum- filled blister. Stage 3: Full thickness tissue loss.
What does a Stage 2 wound look like?
At stage 2, the skin breaks open, wears away, or forms an ulcer, which is usually tender and painful. The sore expands into deeper layers of the skin. It can look like a scrape (abrasion), blister, or a shallow crater in the skin. Sometimes this stage looks like a blister filled with clear fluid.
Is Slough normal in wound healing?
Slough is considered the by-product of the inflammatory phase of wound healing. An essential component of wound bed preparation is the removal of slough from a wound bed. Slough not only contributes to delayed wound healing, it also prevents an accurate wound assessment and can also harbour biofilms.
How do you clean a slough wound?
Wound irrigation, the use of cleansing solutions or a cleansing pad (e.g. Debrisoft®; Activa Healthcare), or the use of dressings – such as hydrogel sheets, honey or iodine cadexomers – can be used to remove slough by clinicians with minimal training.
What is the best dressing to remove Slough?
AIM: Remove slough and absorb exudate. Use hydroactive dressings, or alginate dressings covered by a foam dressing. Primary dressing examples: alginate; hydrofiber; or hydroactive. Secondary dressing examples: high absorbent non-adherent dressing; or foam.
What does a stage 4 wound look like?
A stage 4 pressure ulcer may look like a reddish crater on the skin. Muscles, bones, and/or tendons may also be visible at the bottom of the stage 4 pressure ulcer. An infected stage 4 pressure ulcer may have a foul smell and leak pus.
What are the 3 stages of wound healing in order?
Three Stages of Wound Healing
- Inflammatory phase – This phase begins at the time of injury and lasts up to four days.
- Proliferative phase – This phase begins about three days after injury and overlaps with the inflammatory phase.
- Remodeling phase – This phase can continue for six months to one year after injury.
Are there 3 or 4 stages of wound healing?
The complicated mechanism of wound healing occurs in four phases: hemostasis, inflammation, proliferation, and remodeling.
What does a Stage 3 wound look like?
Stage 3. These sores have gone through the second layer of skin into the fat tissue. Symptoms: The sore looks like a crater and may have a bad odor. It may show signs of infection: red edges, pus, odor, heat, and/or drainage.
Does Slough make a wound Unstageable?
Ulcers covered with slough or eschar are by definition unstageable. The base of the ulcer needs to be visible in order to properly stage the ulcer, though, as slough and eschar do not form on stage 1 pressure injuries or 2 pressure ulcers, the ulcer will reveal either a stage 3 or stage 4 pressure ulcer.
Is yellow slough necrotic tissue?
Necrotic tissue, slough, and eschar
The wound bed may be covered with necrotic tissue (non-viable tissue due to reduced blood supply), slough (dead tissue, usually cream or yellow in colour), or eschar (dry, black, hard necrotic tissue). Such tissue impedes healing.
Does Slough need debridement?
In those wounds that contain only slough, high-risk debridement methods are not considered necessary for its removal. The use of mechanical techniques for removing the slough is regarded as posing a much lower risk to the patient and the wound bed.
Should you Debride Slough?
Slough is marked by its color, which can be yellow, tan, gray, green, or brown. It can be stringy and loose or thick and adherent to the wound bed. It is imperative that slough be debrided to kick-start the healing process and allow for the ingrowth of healthy granulation tissue.
