INFECÇÕES SANGUÍNEAS EM AMBIENTE HOSPITALAR E A RESISTÊNCIA BACTERIANA

Bloodstream infectionin patients with venous catheters causes high rates of mortality in hospitalized patients. The aim of the study was to investigate how bloodstream infections are correlated with antibiotics use and bacterial resistance in hospitalized patients. The study was approved by the Research Ethics Committee of the University Center of Espírito Santo. Blood samples from patients of different age groups were collected in 2017 and analysis of etiological agents was carried out in collaboration with the Clinical Analysis Laboratory Santa Maria. The data were evaluated using the software Origin 8.0 and Microsoft Excel 2016. The results showed a high rate of bloodstream infection in men. Among the 203 positive blood cultures, the most frequent bacteria found were Acinectobacter baumannii, Escherichia coli, Enterococcus sp., Klebsiela pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus andStaphylococcus coagulase negativa. In this study, most bloodstream infectionin hospitalized patients were Klebsiella pneumoniae,Staphylococcus aureus andStaphylococcus coagulase negativawith significant resistance to the antibiotics erythromycin, oxacillin and gentamicin.
