[Preoperative determination of the boundaries of soft tissue necrosis in patients with diabetes mellitus]. / Dooperatsionnoe opredelenie granits nekroza miagkikh tkanei u bol'nykh sakharnym diabetom.

The authors examined 34 patients with diabetes mellitus and purulent diseases of the soft tissues and 40 persons who formed the control group. The study of local microcirculation in the purulent focus, in a purulent and closed wound by determining the oxygen tension in capillary blood (pO2) established by using an noninvasive method that a real possibility for determining the exact boundaries of tissue necrosis has appeared. This makes it possible to excise optimally the necrotic tissues and choose the techniques of applying primary, primary-delayed or early secondary sutures. In addition, the study of the dynamics of pO2 changes allows the course of the wound process to be followed up and, consequently, possible suppuration of the wound to be predicted.

Percutaneous measurement of the capillary blood PO2 was used in 20 normal subjects, 20 patients with diabetes mellitus without purulent pathology, and 34 patients with diabetes mellitus and purulent-inflammatory soft tissues diseases. In patients with diabetes mellitus without purulent pathology, oxygen supply of the skin was reduced by 33%, and in patients with purulent inflammatory diseases--by 55% when compared with that of the normal subjects. After debridement of a purulent wound with drainage and placing the sutures in low PO2 indices at a distance of 1 cm from the wound edge, microcirculation should be restored at day 2-3 after the operation by means of heparin electrophoresis through the perforated drainage tube in the closed wound. This ensures primary healing of 93.8% of the wounds.

[Prevention of wound complications and recurrences in large ventral hernias]. / Profilaktika ranevykh oslozhnenii i retsidivov pri bol'shikh ventral'nykh gryzhakh.

An experience with prophylactics of wound complications and recurrences in treatment of 92 patients with great ventral hernias is analyzed. The incidence of wound complications was decreased from 34% to 9.5%, recurrences from 14% to 2.4%.
