[Malum perforans diabeticorum: treatment with controlled circulatory blockade and regional intravenous administration of antibiotics].

Orthopedic deformations of the feet play an important role in the etiology of the foot ulcers of diabetic patients, together with neuropathy and vascular impairment. The employment of new techniques in the treatment of diabetic foot has considerably improved its prognosis. These are the transient circulatory blockade (TCB) and the regional intravenous antibiotic administration (RAA). This paper reports on the usage of these techniques in the treatment of 24 diabetic patients, 8 women with ages between 41 and 75 (mean 54.7) years, and 16 men with ages between 41 and 75 (mean 59.3) years who were operated on 29 opportunities because of foot ulcer. Most of the patients had different grades of foot infection. Neuropathy was present in all cases and a distal type of arterial occlusion was diagnosed in 8 cases. Foot surgery was performed under regional i.v. anesthesia associated with regional i.v. injection of 1 g Cefotaxine (Calaforan) in 250 ml saline solution which was administered through the same butterfly needle used for the regional anesthesia. The drainage of the foot infection was performed simultaneously with the orthopedic correction of the foot deformities. All patients healed without complications attributable to the bone surgery. Patients operated upon while complicated with foot phlegmons remained longer (31 days) in the hospital than those without infection (18 days). After a follow-up period of 4.7 (1 to 8) years there were 2 recurrencies and 3 patients developed new foot ulcers. All patients were using a normal, soft shoe. We conclude that the TCB and the RAA facilitate orthopedic surgery in diabetic patients with foot ulcers improving their life quality and prognosis.
