Introduction: The ICU environment is considered the focus of Healthcare-related health related infections (IRAS). This is due to the particularities of this environment such as the use of invasive devices, use of immunosuppressants, prolonged hospitalization, colonization by resistant microorganisms, antimicrobial prescribing and the very characteristic of the ICU environment, in addition to the clinical condition of the patient. Knowledge of the bacterial profile of each culture guides the medical team in the initial treatment of infections. Objective: The objective of this study was to verify the incidence incidence and the bacterial profile present in ICU patients of a University Hospital. Material and methods: The study was performed through the analysis of tracheal secretions, blood cultures and urocultures examinations of patients hospitalized from January to June 2018. Data were collected by means of laboratory forms of the service and tabulated in Excel spreadsheet. ®, being divided into positive and negative samples, and a descriptive analysis was performed with absolute and percentage values. Results: In general, the most commonly occurring bacteria were Acinetobacter baumannii (20.3%), Pseudomonas aeruginosa (19.7%), Klebsiella pneumoniae (15.1%), Staphylococcus aureus (11.9%), Staphylococcus negative coagulase (7.2%) and Escherichia coli (5.7%). The most resistant bacterial species were Acinetobacter baumanni, Klebisiella pneumoniae, Pseudomonas aeruginosa, Eschericia coli, Serratia marcencens and Enterobacter cloacae. Conclusion: The data from this study allow the knowledge of the bacterial profile found in hospitalized patients, which may guide the treatment of infections and consequently decrease the selection of multidrug resistant bacteria, helping in the prevention and control of nosocomial infections.
