Wound microflora and antibiotic resistance in burn patients

Aim. To explore the etiological structure of wound microflora and its antimicrobial susceptibility in burn patients treated in hospital burn departments.Materials and methods. The authors analyzed the microbiology testing results of 2354 wound exudates in samples of 1581 patients with severe burns who underwent treatment in the Burn Unit and Department of Anesthesiology, Resuscitation and Intensive Care of the Center for Emergency Medical Care of the Republic of Sakha (Yakutia) in the period from 2016 to 2020. Data processing and antibiotic resistance analysis were performed via AMRcloud online platform (Beta version, 05.07.2022).Results. Of the pathogens isolated in the burn wounds, Staphylococcus aureus accounted for 26.1%, Enterococcus faecalis – 24.5%, Pseudomonas aeruginosa – 11.9%, Klebsiella pneumonia – 9.4%, Acinetobacter baumannii – 7.9% and Escherichia coli – 6.0%. The susceptibility of isolated microbial strains to carbapenems and high resistance to cephalosporins and fluoroquinolones were established.Conclusion. Microbial strains detected in burn patients indicate infection of wounds with representatives of nosocomial flora and their high resistance to commonly used antibiotics.
