Microbiological findings and antimicrobial susceptibility analysis: emergency general abdominal surgery profile

Abstract

Background: Antimicrobial resistance is a worldwide problem. In patients requiring emergency surgery, antibiotics are an important assistance additional to surgical intervention.

Objective: Analize peritoneal fluid cultures obtaines from patients who underwent emergency surgery.

Methods: A prospective cohort of emergency abdominal surgical patients were enrolled. Peritoneal fluid cultures were taken and processed according to standarized technique.

Results: A 39.4% of positive cultures was found. E. coli was the most common bacteria identified. Five positive cultures for P. aeruginosa stand out. E. coli had 25% resistance to ampicillin/sulbactam and 19% for quinolones.

Conclusion: Resistance found was lower than international reports, but still noteworthy. Knowledge of local bacteria profile and antimicrobial resistance is important for local antibiotic hospital policy.
