Abstract:
Introduction: Septic-purulent nosocomial pathology is the major public health problem. One
of the nosocomial infections particularity is the diversity of causative agents, which depend on the
profile of the department.
Materials and Methods: In this study was used the transversal retrospective method of
analysis. There were isolated 2013 strains of microorganisms from the patients with septic-purulent
infections, hospitalized in orthopedics and traumatology departments.
Results: The result of the study found that the etiological structure was varied and included 18
species of microorganisms and predominant Gram-positive (63,2%). From gram-positive microorganisms predominate were S.aureus- 62,02%, S. epidermidis- 15,02% and E. faecalis- 20,2%.
Gram-negative microorganisms are isolated in 35,56 %, P. aeruginosa- 30.02 %, E.aerogenes 24.3
%, E. coli - 12.3 %, Citrobacter- 17,59 %, Proteus - 10,06 % and Klebsiella - 5,30%. Is confirmed
the polyetiological features of septic-purulent infections. At the 43,36% patients were isolated the
combination of microorganisms from 2 to 5 strains. In young patients were isolated mainly
monocultures, while in the elderly were detected association of 2-5 strains of microorganisms. Also,
a decrease of gram-positive strains of microorganisms was found with increasing age of the patients
and, conversely, an increase of gram-negative microorganisms.
Conclusion:
Septic-purulent nosocomial infections in trauma patients are characterized by the
predominance of gram-positive microorganisms as a causative agents.There were identified a high
rate of association of microorganisms isolated in pathological eliminations, and increasing of gramnegative microorganisms disorders at elderly patients.
