Introduction: Hospital infections are a worldwide problem, challenging health professionals and systems. The surgical patients are more exposed to nosocomial infections. Objective:To determine the bacterial profile of the nosocomial infections of patients approached to surgical procedures by the general surgery team in a tertiary hospital. Material and Methods: The patients included in this study were approached to surgical procedures by the general surgery team and developed bacterial nosocomial infection documented by one or more positive cultures in 2019 and 2020. The variables analyzed were genre, age, surgical type (urgency or elective), culture sample, infectious focus, isolated bacterial species and its antibiogram, bacterial multidrug resistance and presence or absence of more than one bacterial species isolated in the sample analyzed. Results: Most of the patients were male, surgically treated on an urgent/emergent and with average age of 41 years. The main infectious focus was abdominal, whose the main isolated etiological agents were (27%), Enterococcus faecalis (16%), Klebsiella pneumoniae (14%). There was also an expressive number of cultures demonstrating Acinetobacter baumannii in respiratory infections. Furthermore, 71% of microorganisms isolated from biological samples were multidrug-resistant. Conclusion: The study's findings may promote changes in the empirical antibiotic therapy used in the institution under study, since the high rate of drug resistance found is a risk to the studied population, even more alarming in the context of the frequent isolation of bacterial species.
