1st line

2nd line

 

 

       Necrotic

 Necrotic layer of

 devitalized tissue

 May be black/brown

 May be soft/hard

 May produce offensive odour

Rehydration and removal of necrotic tissue

If vascular insufficiency or if wound requires sharp debridement contact wound management/diabetes specialist podiatrist: See Tissue Viability Pathway

Patients with active diabetic foot disease should be referred to podiatry, see Tayside Diabetes MCN Handbook Screening and Management of Foot Complications Click Here

 

 Assess vascular status to ensure adequate blood supply.

Refer to vascular service if:  - ischaemic tissue loss

                                               - pain at rest 

 

Wounds should be closely monitored and dressing changed regularly.

 

Debride necrotic/dead tissue using the most suitable form of wound debridement. Sharp debridement should only be carried out by appropriately trained practitioners.

 

Dressings used to rehydrate wounds, e.g.  Flaminal Hydro should be applied cautiously to patients with limb ischaemia or dry gangrene.  Dry gangrene can rapidly progress to wet gangrene with serious consequences.

 

Dry gangrene should be kept as dry as possible especially at the line of demarcation with sharp debridement to this area to remove dead material.

 

If patient has loss of protective sensation then regular wound inspection is required to detect any changes.

 

It is important to check the wound for signs of infection – Please note the clinical signs of infection may be absent in patients with neurological deficits.

 

Avoid occlusive dressings on infected wounds.

 

Offload pressure from wound site – please see NHST guidance for the use of small devices in the treatment and prevention of grade 1 pressure ulcers (Docstore link)

 

For guidance on dressing selection for infected wounds see section 12: Wound Infection.

 

For systemic treatment of wound infection refer to the Tayside Area Formulary Primary Care Antibiotic Man or Diabetes handbook for information on  antibiotic choice.

 

Notes:

If patients is on Biologics or Methotrexate and you suspect infection, contact patients GP or Biologics Specialist Nurse for advice as temporary withdrawal may be required.

 

Soft silicone foam dressing are the preferred choice on the foot as they effectively  mould and conform to uneven contours, provide thermal properties and provide protection from footwear for bony vulnerable areas.

Granulating


 Wound has 'granular' 

 appearance and looks red and

 moist

 Protect from trauma and

 maintain moist, warm

 environment

Soft Silicone Foam

 

If wound infection suspected consider an antimicrobial dressing see section 12

Epithelialising


 

 Red/pink, new skin cover

 extending from wound edges,

 may have islands of new

 epithelium in main areas of the 

 wound bed

 

 

 

Protect and maintain optimal wound healing environment
