Sloughy Wounds: What Slough Means and How to Manage It
Slough is the most misread surface in wound care. It is not automatically a sign of neglect, and it is not automatically a sign of infection, but it changes both the dressing plan and the supply list the moment it appears.
What is slough made of?
Slough is devitalised tissue: a mixture of fibrin, dead cells, wound fluid and bacteria that settles on the wound surface. It is soft and moist, and it lifts from the wound bed rather than being anchored to it. That physical difference is what separates it from eschar, which is dry, dark and firmly attached.
How do you distinguish slough from other wound tissue?
| Tissue | Colour and texture | Attached to the bed? | What it usually signals |
|---|---|---|---|
| Slough | Pale yellow, grey or white; soft and moist | Loosely, can be lifted | Devitalised tissue; may be normal in a moist wound |
| Eschar | Black or dark brown; dry, hard, leathery | Firmly, often cannot be lifted | Necrosis; needs clinician assessment before removal |
| Granulation | Red or pink, glossy, granular | Part of the bed | Healing tissue; should be protected, not disturbed |
| Epithelialisation | Pale pink to silvery, advancing from the edges | Forms the new surface | Closure is progressing |
| Maceration around the wound | White, soft, wrinkled peri-wound skin | Outside the wound bed | Excess moisture; a dressing or exudate failure |
The last row is the one that most often changes a supply order. Macerated peri-wound skin usually means the dressing is holding fluid against the skin instead of moving it away, and the fix is a different cover rather than a stronger contact layer.
When does slough need to be removed?
The decision is clinical, and it depends on the wound, the patient and the blood supply to the area. Dead tissue can hold bacteria and prevent the wound from closing, but removing it aggressively at every dressing change damages new tissue and is painful for the patient. Most teams compromise: the dressing maintains a moist environment so the slough loosens on its own, the clinician removes what lifts easily at the change, and formal debridement is scheduled as a separate procedure when it is needed.
How does dressing choice change?
A sloughy wound is usually wetter than a clean wound, so the cover dressing moves up the absorbency scale. Three things change together: the contact layer must not bond to the wound bed, the cover must handle more fluid, and the change interval must be short enough that the wound does not sit in a saturated dressing between rounds.
What should be documented at each change?
For a care home or clinic, the sloughy wound plan translates into a short consumable list rather than a long one. The items are a non-adherent interface layer, an absorbent cover in at least two absorbencies, a fixation tape matched to skin condition, and the barrier products that protect peri-wound skin. The fixation formats worth holding are paper tape for fragile skin, transparent tape so an exudate check does not require lifting the dressing, and wound closure strips for the small superficial breaks that appear when peri-wound skin is repeatedly stressed. Where debridement instruments are reprocessed on site, the cleaning step ends in a sterility record, and a five-pack trial of its biological indicators covers the weekly spore test behind that record.

Frequently Asked Questions
What does slough look like on a wound?
It is soft, moist, pale yellow, grey or greyish-white tissue that sits on the wound surface and can be lifted or partly wiped away. It is not firmly attached to the wound bed the way eschar is, and it does not bleed when touched. A wound with slough often has an uneven, mottled surface rather than the clean red or pink of healthy granulation.
Is slough always a bad sign?
Not by itself. A small amount of slough can be part of normal healing in a moist environment, and some dressings deliberately create a moist interface that loosens it. What matters is the trend: a wound bed that is mostly slough and not reducing over successive rounds is not progressing, and that is a clinical finding rather than a supply problem.
Should slough be removed at every dressing change?
No. Aggressive removal at every change is painful and can strip new tissue. The decision to debride, and the method, belongs to the clinician and depends on the wound, the patient's condition and the vascular status. In practice many teams let an appropriate dressing loosen the slough and remove only what lifts easily, with formal debridement scheduled separately.
Which dressings are used on a sloughy wound?
Dressings that maintain a moist environment and manage exudate without bonding to the wound bed: a non-adherent or gel-forming contact layer, an absorbent cover, and where indicated by the clinician a product selected to support autolytic debridement. The cover is chosen for exudate volume, because a sloughy wound is usually wetter than a clean one.
