Wound dressings in diabetic foot disease

Wound dressings represent a part of the management of diabetic foot ulceration. Ideally, dressings should alleviate symptoms, provide wound protection, and encourage healing. No single dressing fulfills all the requirements of a diabetic patient with an infected foot ulcer. Dressings research in this area is generally poor. However, each category of dressings has particular characteristics that aid selection. Nonadhesive dressings are simple, inexpensive, and well tolerated. Foam and alginate dressings are highly absorbent and effective for heavily exuding wounds. Hydrogels facilitate autolysis and may be beneficial in managing ulcers containing necrotic tissue. Dressings containing inidine and silver may aid in managing wound infection. Occlusive dressings should be avoided for infected wounds. All dressings require frequent change for wound inspection. Heavily exudating ulcers require frequent change to reduce maceration of surrounding skin. Dressing choice should be guided by the characteristics of the ulcer, the requirements of the patient, and costs.
