Analysis of bacterial culture and antimicrobial susceptibility of chronic rhinosinusitis

OBJECTIVE To analyze the bacteriological characters and drug sensitivity in patients with chronic rhinosinusitis and to provide basis for clinical treatment. METHODS The pur ulent discharges taken from middle meatus were cultured for bacteria and the drug sensitivity was determined. RESULTS In 43 specimens, the positive rate of bacter ia culture was 86.04%. Aerobic bacteria were present in 91.90%, anaerobic bacteria were present in 8.10%. A total of 20 bacteria were found in culture, mainly Epidermal Staphy, Pseudomonas aer uginosa, Staphylococcus aureus. The result of drug sensitivity demonstrated that Cefoperazone sulbactam, Cefuroxime sodium were good in vitro activity to aerobic bacteria. CONCLUSION The most common bacteria of chronic sinusitis are aerobic bacteria. Before treatment by antibiotics, the drug sensitivity should be performed. If the situation is not allowed, we should choose the broad-spectrum antibiotics that is resistance to β-lactam, such as Cefoperazone sulbactam, Cefuroxime sodium etc.
