Diabetic Foot Infection

Of the total number of non-traumatic leg amputations 85% are caused by a diabetic ulcer. It is estimated that 3-4% of patients with diabetes routinely suffer diabetic ulcers or deep infections. About 15% of patients with diabetes develop ulcers in life and, once they appear, these lesions grow eight times the risk of amputation for that patient.
Beyond statistics, it is clear that a diabetic ulcer has major implications on patient health and quality of life, with serious consequences if it is ignored and left to get in an advanced stage.

 

Diabetes mellitus is a chronic disorder of carbohydrate metabolism and, globally, witnessed a near epidemic spreading. Since type 2 diabetes is age-dependent component and is expected to expand the number of people affected by this disease even if only based on the evolution of population age. In the subsequent diabetic complications, diabetic foot syndrome (SPD) occupies a central place.

The primary requirement for the occurrence of diabetic foot lesions is the existence of a (poly) diabetic neuropathy and / or peripheral arterial circulation disorders. Although statistics vary to a certain extent, the following distribution can be considered:

In approx. 45% of cases the cause is diabetic neuropathy, the other 45% of the cases, a combination of neuropathy and circulatory disorder, and in 10% of cases it is a peripheral circulatory disorder.

Basic factor of all lesions in diabetic treatment is to maintain blood glucose within normal limits, that is, at the same time, the best therapy to prevent neuropathy. Other conservative therapies focus on improving central and peripheral circulation.

The main problem of diabetic ulcers is particularly high risk of infecting them. Although very few signs of a diabetic ulcer infection are observed in the surrounding area, they can usually be considered also infected. Terms of expanding a diabetic foot infections are very favorable, which is the reason for the consistent systemic antibiotic therapy.

For the tipical treatment of neuropathic ulcers are recommended:

– Issuance of any request by an absolute direct pressure on wound (use the frame or wheelchair mobility and bed rest)

– Therapy with hydroactive wet bandages

– Surgical treatment (in certain situations)

– Use of orthopedic shoes

Local wet therapy of diabetic foot lesions supports the body’s biological healing processes (cell proliferation in a moist environment) by: preventing infection and / or reduction of microbial load, preventing the onset of necrosis or remove existing ones and adapt to each stage of healing wound (cleaning, granulation and epithelization).

Clinical studies have demonstrated that treatment with modern hydroactive wound dressings is well tolerated by the patient, do not require hospitalization and can be performed in an ambulatory setting.

Dressings used in modern treatment are based on the hydroactive principle and provide optimum conditions for wound healing in each of the stages (phase I – exudative, phase II – the grain and phase III – the epithelium).
