The article presents a brief biography of the permanent head of the anesthesiology and resuscitation group in wounds and wound infections department of the Federal State Budgetary Institution “A. V. Vishnevsky National Medical Research Center of Surgery” Ministry of Health of Russia Alfred A. Zvyagin (05/22/1940) in honor of his 80th anniversary, of which 52 years passed within the walls of the A. V. Vishnevsky institute of surgery!

NPT is part of the daily management of complex wounds with delayed healing. It is essential in 2018 to understand the mechanisms of action of the various machines available on the wound market in France. In order to put the right indication for a defined clinical problem to know the difference between fixed and heavy techniques, imposing immobilization of the patient due to the need for a permanent connection and the simpler, ambulatory techniques that combine effective negative pressure while allowing a better quality of life. The recent contribution of the instillation has completed the offer by opening the possibility of instilling in the wound variable liquids in their composition and their effect. The recent introduction of a new foam also suggests the possibility of cleaning the wound with a tool hitherto reserved for the promotion of granulation tissue.

As a predictive indicator of tissue viability in multiple muscle lesions used the percentage of high-, medium- and low amplitude contracting reactions (СR) or their absence, recorded by stimulation impedance myography contraction (SIMC). After examining the boundaries of the scattering of amp-omic muscle curves of the limbs, the patients determined the distribution of maximum contractile reactions (MSRs) by the angles of tilt curves in the coordinate plane. After examining the boundaries of the scattering of amp-omic muscle curves of the limbs, the patients determined the distribution of maximum contractile reactions (MCRs) by the angles of tilt curves in the coordinate plane. Average sectoral values of MSR were distributed in reverse dependence of amplitudes on the amount of stimulus in the form of hyperbole containing high-, medium-, and low-amplitude MSD, the percentage of which were based on the profiles of histograms of patients with known clinical diagnoses. Comparison of histogram profiles of different stages of chronic ischemic syndrome among themselves showed their high distinguishing ability and correlation of histograms with diagnoses.

Inferior gluteal artery pseudoaneurysms are rare, and most of the cases are due to blunt (pelvic fractures, femur’s dislocations) or penetrating trauma. Herein, we present a case of traumatic blunt rupture of an inferior gluteal artery pseudoaneurysm in adolescent 15th years old. Patient went through the complex examination and endosurgical treatment: endovascular occlusion of inferior gluteal artery and endoscopic evacuation of the large hematoma. Patient in short time came back to his ordinary live and sport.

The article presents a clinical observation of thoracic vertebrae bodies chronic hematogenous osteomyelitis, which proceeded with the formation of right-sided pyothorax, an abscess of the retroperitoneal space, an external fistula through an anatomically weak place of the posterior abdominal wall, complicated by severe sepsis. Complex staged surgical debridement of purulent foci in combination with intensive drug therapy led to the patient's recovery.

The article presents the experience of treating a patient with diabetic foot syndrome complicated by the development of osteomyelitis of the first metatarsophalangeal joint and cuboid bone, putrid phlegmon of the left foot. The disease proceeded against the background of a pronounced systemic reaction of the body to the presence of purulent infection focus in a polymorbid patient (IHD: postinfarction cardiosclerosis, chronic heart failure of grade 2 (FC1), chronic lymphovenous insufficiency). The complex treatment of the patient included surgical debridement of the purulent left foot focus with a hydrosurgical scalpel, disarticulation of the first toe, NPWT in the postoperative period, pathogenetic and symptomatic treatment, which were aimed at the early transition of the wound to the reparative stage. The second phase of the wound healing process was reached by the 18^th day of treatment, which made it possible to perform skin grafting. On the 29^th day of treatment, the patient was discharged in satisfactory condition with good cosmetic and functional results.

Surgical debridement is the gold standard in helping patients with purulent foci of any etiology and localization. The outcome and prognosis of treatment, as well as functional and cosmetic results, depend on the radicalism, thoroughness, and accuracy of this operation. Surgical debridement of the purulent focus is performed throughout the entire period of the existence of surgery and its underlying principles undergo minimal changes over time. However, at all specialized congresses and conferences, questions of terminology and nomenclature are always actively discussed in relation to this operation, and additional methods of physical, chemical, and mechanical effects on the wound are constantly being reported with the aim of cleansing and transferring it to the reparative stage. All these aspects require discussion, reflection and regular exchange of experience, in connection with which it was planned to hold this forum (the previous conference was held in May 2014, its materials can be found at: https://woundsurgery.ru/mezhdunarodnaya-nauchno -prakticheskaya-k-6 /).
