Role of Negative Pressure Wound Therapy in the Management of Diabetic Foot Ulcers

• The aim of this study will be to assess negative pressure wound therapy in treating diabetic foot ulcers.


Diabetic Foot ulcers are a major cause of admission in diabetic patients, and comprise a disproportionately high number of hospital days because of multiple surgical procedures and prolonged length of stay in Hospital.

The improvement in diabetes therapy and the reinforcement of guidelines have reduced the amputation rate. The approach to diabetic foot ulcers has allowed the availability of several medical options to ensure the best local condition and wound healing.

Negative-pressure wound therapy is a non-invasive therapy system that employs a controlled negative pressure using a vacuum device to promote wound healing by removing fluid from open wounds through a sealed dressing or a foam dressing connected to a container.

An earlier study has shown that NPWT reduced the need for subsequent amputations in a 6-month follow-up period. This reflects the importance of this device in management of DFUs and prevents its complications.

As most of the diabetic wounds present with infection, the success of NPWT is still highly dependent upon the adequacy of surgical debridement and antimicrobial coverage.

NPWT provides a moist wound environment ideal for re-epithelialization, growth factor action, angiogenesis, and granulation promotion.

Edema reduction produced by NPWT decreases interstitial pressure and positively promoting wound vessel formation and improving wound circulation and lymphatic drainage, increasing the availability of nutrients, oxygen and antibiotic therapy in the wound area. Some studies showed that NPWT promotes an improvement of balance between proteases and their inhibitors and influences cytokine modulation and promotes a positive wound environment.

Accurate classification of diabetic foot ulcers according to Wagner's classification of ulcers is essential for inter-clinician communication, assessment of healing tendency during management by NPWT.

Medical and Biotech [MESH] Definitions

The application of a vacuum across the surface of a wound through a foam dressing cut to fit the wound. This removes wound exudates, reduces build-up of inflammatory mediators, and increases the flow of nutrients to the wound thus promoting healing.

Common foot problems in persons with DIABETES MELLITUS, caused by any combination of factors such as DIABETIC NEUROPATHIES; PERIPHERAL VASCULAR DISEASES; and INFECTION. With the loss of sensation and poor circulation, injuries and infections often lead to severe foot ulceration, GANGRENE and AMPUTATION.

Lesion on the surface of the skin of the foot, usually accompanied by inflammation. The lesion may become infected or necrotic and is frequently associated with diabetes or leprosy.

An ulceration caused by prolonged pressure on the SKIN and TISSUES when one stay in one position for a long period of time, such as lying in bed. The bony areas of the body are the most frequently affected sites which become ischemic (ISCHEMIA) under sustained and constant pressure.

Peripheral, autonomic, and cranial nerve disorders that are associated with DIABETES MELLITUS. These conditions usually result from diabetic microvascular injury involving small blood vessels that supply nerves (VASA NERVORUM). Relatively common conditions which may be associated with diabetic neuropathy include third nerve palsy (see OCULOMOTOR NERVE DISEASES); MONONEUROPATHY; mononeuropathy multiplex; diabetic amyotrophy; a painful POLYNEUROPATHY; autonomic neuropathy; and thoracoabdominal neuropathy. (From Adams et al., Principles of Neurology, 6th ed, p1325)
