EPIDEMIOLOGY OF NOSOCOMIAL INFECTION COMPLICATIONS IN A SURGICAL CLINIC

The analysis of the data of literary sources of domestic and foreign researchers on the problem of the occurrence and development of nosocomial infections in general and in the surgical departments in particular is carried out. The relevance of the study is confirmed by the following data: the spread of nosocomial infections in the Russian Federation is 2.5 million annually; the minimum damage inflicted by them in Russia alone is approximately 6-7 million rubles. The data of foreign scientists have been studied, suggesting that infections in the field of hirirurgic intervention were recorded in 13% of cases after performing "clean" operations, in 16% after and in 29% after < contaminated>. In St. Petersburg, with selective studies, the frequency of infections in the field of surgical intervention revealed 9% of patients among 1,500 operated It was revealed that the number of potential causative agents of nosocomial infections increases every year due to opportunistic bacteria that differ in biological characteristics from hospital strains and have multiple drug antibiotic resistance. A retrospective and prospective analysis of the frequency of occurrence of microorganisms in patients of the surgical department of 2008-2019 was carried out. The microbial spectrum and prevalence of nosocomial infection pathogens in the surgical department were investigated. An epidemiological analysis of the causative agents of nosocomial infection in patients with pneumonia, infections in the surgical field and urinary tract, as well as with generalized infections, was carried out. The analysis of the bacterial flora of the clinical microbiological culture of the wound discharge, sputum, urine and blood was carried out. The following microorganisms were most prevalent in these samples: Staphylococcus aureus, Acinetobacter baumannii, Candida albicans, Klebsiella pneumonia. A tendency to increase the proportion of Candida albicans in patients of the surgical department, as well as a high prevalence of Staphylococcus epidermidis in blood cultures, was revealed.
