# Wound debridement

> Wound debridement is the removal of dead or damaged tissue from a wound so that healthy tissue can heal. There are gentle and sharp methods, and the right one depends on your wound, your circulation and your health. It may help healing, but how much isn't certain.

- **It removes dead or damaged tissue** from a wound so healthy tissue can take its place.
- **There are several methods,** from gentle dressings to sharp removal by a trained clinician.
- **No method has been shown to be clearly best,** so the choice is fitted to your wound and your health.
- **Your circulation is checked first,** because the wrong method on a poorly supplied wound can make things worse.
- **You give consent beforehand,** and you can withdraw it at any time.

## What is wound debridement?

Wound debridement is the removal of dead, damaged or contaminated tissue from a wound, including slough (soft dead tissue) and biofilm (a slimy layer of bacteria), until healthy tissue shows [1]. It's different from cleaning a wound, and it isn't amputation or removal of healthy tissue [2].

Dead tissue can delay healing and raise the risk of infection [3][4], so taking it away gives new tissue a base to grow from [5]. Methods include dressings that soften dead tissue using your body's own moisture (autolytic), sharp removal, enzyme treatments and ultrasound [1].

## What is wound debridement used for, and does it work?

It's best studied in diabetes-related foot ulcers, where it's seen as an important part of wound care [6]. Even so, in adults the proof that any one method heals these ulcers better than another, or than simple moistened gauze, is weak [7]. Dressings that soften dead tissue increased healing, and maggot therapy reduced amputations without clearly increasing complete healing [8]. Ultrasound-assisted debridement was linked with a higher healing rate, though the research behind it is limited [9]. Guidelines still prefer sharp debridement for these ulcers [10].

For venous leg ulcers in adults, the proof that actively removing dead tissue helps healing is limited [11]. So debridement may help, but it's no guarantee of faster healing.

## Is wound debridement right for me?

Debridement suits wounds with slough or dead tissue, and few wounds are unsafe to debride when the right method is chosen [5]. Before starting, a clinician should check your wound can heal and assess you and your wound as a whole [12][2]. Your circulation is checked first, because debriding a wound with poor blood supply can extend the dead tissue [1].

Extra care is needed with sharp or surgical debridement if you have a clotting problem, take blood thinners, or have diabetes or poor leg circulation [11]. One nursing guideline advises against sharp debridement when blood flow to the foot is significantly reduced, and for babies and children [3]. With dry gangrene from poor circulation, debridement should only be started by the vascular team, ideally after blood flow is restored [5]. Dressings that soften dead tissue aren't recommended for infected wounds [11].

## What happens during wound debridement?

First, your clinician explains the procedure and asks for your consent, which you can refuse or withdraw at any time [2][3]. Sharp debridement should only be done by a clinician with training and proven competence [11].

What it feels like depends on the method. Sharp debridement uses a scalpel, scissors or forceps and, in experienced hands, is often pain free [5]. Surgical debridement usually needs an anaesthetic [1]. Enzyme treatments usually cause only minor pain [1], and softening dressings cause little pain but can take weeks [5].

There's no set number of sessions. One consensus panel suggests starting early, with weekly debridement at first [1]. For adults with diabetes-related foot ulcers, enzyme treatment is usually done every day or every few days, with healing, infection and comfort checked as you go [10]. It can take a few days to tell whether enough dead tissue was removed [1].

## What are the risks of wound debridement?

Sharp and surgical debridement carry real risk even in skilled hands: pain, damage to tissue under the wound, slower healing, blood loss and infection [2]. In a wound with poor circulation, removing tissue may extend the dead area [1]. Wet-to-dry gauze can damage healthy tissue and cause discomfort [10]. Ultrasound causes less discomfort than sharp debridement, but there's a potential risk of exposure to airborne microorganisms from the wound [10].

## How does wound debridement compare with other options?

No method has been shown to heal diabetes-related foot ulcers clearly better than the others, and the comparisons are low quality [7][8]. Each has trade-offs:

- **Sharp debridement** is fast and selective, but needs a trained clinician [5].
- **Softening dressings** are gentle and cause little pain, but are slow and suit small or shallow wounds [5].
- **Maggot therapy** can remove dead tissue quickly where surgical debridement isn't possible, and should be prescribed by trained people [13].
- **Ultrasound** can be an alternative when sharp debridement isn't suitable [9].

Many wounds need more than one method. The choice rests on your wound, the clinician's skills, your tolerance and preferences, and cost [8]. If sharp methods aren't for you, it's fine to ask about gentler options.

## When to see a podiatrist

Ask a podiatrist or your GP about debridement if a wound has dead tissue or isn't healing as expected. If you have a diabetes-related foot ulcer that hasn't progressed after 4 weeks of appropriate treatment, ask for a referral to a multidisciplinary foot care team [14].

During treatment, say so if you feel pain or uneasy. Sharp debridement should stop if you or the clinician become uncomfortable or unsure, or if there's pain, damage to underlying structures or excessive bleeding [3].

See your GP or a podiatrist the same day if:

- you have diabetes and a wound, sore, blister or colour change on your foot, or a foot ulcer with new redness, swelling, discharge, pain or throbbing, or a temperature above 38.3ºC or below 36ºC [15];
- you have spreading redness, heat, swelling or pus in your foot;
- you have gangrene, a deep ulcer (bone, joint or tendon showing), redness spreading up the leg, or an abscess [14].

For urgent advice when it isn't an emergency, call healthdirect on 1800 022 222 (24 hours a day), or go to a Medicare Urgent Care Clinic.

Go to the nearest emergency department if you have diabetes and a foot infection that's spreading fast, with a fever and feeling very unwell [14].

Call 000 and ask for an ambulance if a foot wound or infection comes with confusion or slurred speech, severe shivering or muscle pain, passing little or no urine, severe breathlessness, or mottled or discoloured skin, or if your leg or foot suddenly turns cold and pale or blue.

## Common questions

### Does debridement hurt?

It depends on the method. Sharp debridement by an experienced clinician is often pain free, while surgical debridement usually needs an anaesthetic. Enzyme treatments usually cause only minor pain, and softening dressings cause little pain. Tell your clinician if you feel pain or uneasy at any point, as you can ask for the procedure to stop.

### Can I remove dead skin or callus from my wound or foot ulcer myself?

It's best not to. Debridement is done after your circulation and wound have been checked, and some methods carry real risk even in skilled hands. If a wound has dead tissue or hard skin around it, ask a podiatrist or your GP about the safest way to deal with it.

### Who can perform sharp debridement?

A clinician who has had training and can show they're competent, including knowing the structures under the skin. One nursing guideline refers wounds on a leg with poor blood supply to a podiatrist rather than having a nurse remove tissue. Ask who will be treating you and what training they have.
