CHARACTERISTICS OF AEROBACTERIA IN POSTOPERATIVE CHRONIC RHINOSINUSITIS AT NATIONAL ENT HOSPITAL
Main Article Content
Abstract
Objective: To describe the antibiogram in adult rhinosinusitis patients who had bacteria identified during surgery at the National ENT Hospital. Methods: Patients ≥ 16 years old, diagnosed with chronic rhinosinusitis, had endoscopic sinus surgery at the hospital from January 2023 to August 2023. Cross-sectional descriptive study. Results: Positive culture rate was 84/110 patients, accounting for 76.36%. 15 types of bacteria were isolated, of which the 3 species with the highest rate were: S.epidermidis (60.7%), S.aureus (11.9%), H.i (5.8%). S.epidermidis is 100% sensitive to linezolid, vancomycin, tigecycline, highly resistant to cephalosporin, meropenem, imipenem (90%), amoxicillin, benzylpenicillin (100%). S.aureus is highly sensitive to linezolid and vancomycin (100%), gentamycin and co-trimoxazole (80%), highly resistant to quinolone antibiotics, amoxicillin, benzylpenicillin, macrolide (> 70%). H.i is sensitive to most antibiotics but 100% resistant to co-trimoxazole and 80% resistant to cefuroxime. Conclusion: E.epidermidis is the most common bacteria, with a high rate of antibiotic resistance.
