Objective: To determine the frequency of common bacteria and antibiotic sensitivity pattern of ear discharge in patients with chronic otitis media. Study Design: Descriptive Cross Sectional study. Setting: Department of ENT, Northwest General Hospital & Research Centre, Peshawar. Period: February to September 2019. Material & Methods: A total of 196 patients of both gender and age between 13 to 60 years with clinical diagnosis of active chronic otitis media were recruited through consecutive sampling technique. After detailed history and relevant examination, demographic data was recorded and pus specimens were collected from the infected ear on cotton swabs. They were sent to pathology laboratory of hospital for culture of common bacteria (E.coli, Pseudomonas aueroginosa, Proteus mirabilis, Staphylococcus aureus and Klebsiella spp) and their respective antibiotic sensitivity (Co-trimoxazole, Co-Amoxiclav, Ciprofloxacin, Ampicillin, Imipenem, Ceftriaxone and Cefixime). Results: Bacterial isolates were analyzed as 48% Staph aureus, 28% Pseudomonas, 12% Proteus mirabilis, 8% E. coli and 4% Klebsiella spp. Imipenem was sensitive to 94%, ceftriaxone 84%, ciprofloxacin 80%, co-trimoxazole 66%, ampicillin 63%, cefixime 45% and co-amoxiclav against 43% of total bacterial isolates. Conclusion: The common causative organism for active chronic otitis media was Staph aureus followed by Pseudomonas. Imipenem was the most sensitive antibiotic against majority of bacterial isolates followed by ceftriaxone and ciprofloxacin. [ABSTRACT FROM AUTHOR] |
