[Prevention of extremities amputation in patients with diabetic foot complications].
In order to decrease the number of amputations for "diabetic foot", these patients should undergo elective or delayed operations. It is obligatory before the operation to correct carbohydrate metabolism and hemodynamics. Sodium succinate in combination with conventional angioprotective treatment is used for this purpose. Microcirculation is evaluated using oxymonitor ISM-2 and tetrapolar rheography. Blood flow disturbances are evaluated according to ultrasound dopplerography data. Operations are performed with the use of a primary or delayed suture at the definite level of the extremity where oxygen tension of the skin is not lower than 33 mm Hg, and the index of minute blood flow--not lower than 1.8 ml/min per 100 cm3 of the tissue. When operating on the foot it is obligatory to leave loose excessive brims of tissues to facilitate the placement of broad-grip sutures without tension. It is advisable to use through flowing--aspiration drainage and to perform surgical treatment of the deep phlegmon of the foot through club-shaped approach.
