Wound debridement

What it is

Wound debridement removes dead or infected tissue (slough, necrosis) and biofilm from a wound so healthy healing can proceed. Methods include sharp debridement (scissors/scalpel by a trained clinician), autolytic dressings, larval (maggot) therapy, enzymatic agents and mechanical pads.

Why it is done

It is used for chronic wounds such as leg ulcers, pressure ulcers and diabetic foot ulcers where dead tissue stalls healing and harbours bacteria, and after some injuries and burns.

How to prepare

The wound is assessed for depth, circulation and infection (diabetic foot wounds need vascular and infection assessment as a priority). Tell the team about blood thinners, allergies and pain levels — sharp debridement may need local anaesthetic or analgesia beforehand.

What happens during the procedure

For sharp debridement in clinic, after cleaning (and numbing where needed) the clinician lifts and trims away dead tissue with sterile instruments until healthy tissue is reached; some bleeding is expected and controlled with pressure or dressings. Sessions take about 10 to 30 minutes. Larval therapy applies contained medicinal larvae in a dressing for several days instead.

Afterwards — recovery & results

The wound is redressed with a plan for repeat reviews; debridement is often repeated over weeks as part of wound care, alongside compression (for venous leg ulcers), offloading (for diabetic foot wounds) or pressure relief. Healing progress is measured by wound size tracking.

Risks & considerations

Risks include pain, bleeding, and exposing deeper structures if the wound is deeper than it appeared — which is why assessment and trained operators matter. Debriding a wound with poor blood supply before vascular review can worsen it, so circulation is checked first.
