Particularities of the Etiological Structure of Nosocomial Infections in Hospitals of Orthopedics and Traumatology Profile

PARTICULARITIES OF THE ETIOLOGICAL STRUCTURE OF NOSOCOMIAL INFECTIONS IN HOSPITALS OF ORTHOPEDICS AND TRAUMATOLOGY PROFILE (Abstract): Determination of etiological structure of septic-purulent nosocomial infections (SPNI) in hospitals of orthopedics and traumatology profile. Materials and methods: there were analyzed 2013 strains of microorganisms isolated from the patients with SPNI. Results: it was established that Gram-positive microorganisms (63.19%) prevail in hospitals of Orthopedics and Traumatology profile, including S. aureus (39.19%), E. faecalis (12.76%), S. epidermidis (10,13%), followed by Gram negative microorganisms (35.56%), including P. aeruginosa (10.68%), E. aerogenes (8.64%), E. coli (4.32%), C. diversus (4.37%), P. vulgaris (2.58%), Kl. pneumoniae (1.54%). It was found that Gram positive strains prevail in young population, but Gram negative bacteria and fungi prevail in old population. Also, i t has been shown that pathologic foci with associations of microorganisms predominate among old population, while monocultures prevail among young population. During the last years, it was observed an increase of SPNI caused by associations of microorganisms. Conclusions: The septic-purulent pathology has a polyetiological character in hospitals of orthopedics and traumatology profile, both in general population, as well in the hospital outbreaks among patients.
