BACTERIOLOGY OF EAR DISCHARGE IN SUPPURATIVE OTITIS MEDIA IN A TERTIARY CENTRE OF NEPAL

Abstract

Objective: To find out the various bacteria causing suppurative otitis media and to assess their sensitivity pattern to different commonly used antibiotics.

Materials and Methods: This is a prospective study conducted from June 2013 to May 2015 in Bir Hospital. 129 patients were selected for the study. Ear discharge samples were collected and sent to the laboratory using standard technique. The culture and sensitivity reports were then analyzed.

Results: Majority of the patients were from 21 to 30 years of age group. 89.9% of ear swabs grew bacteria. 72.9% of bacterial isolates were monomicrobial and 17.1% were polymicrobial. The most common bacterial isolate was Staphylococcus aureus followed by Pseudomonas aeruginosa. Cephalexin and Ceftriaxone were found to be the most sensitive antibiotic.

Conclusion: Antibiotics should be selected carefully taking into consideration the bacteriology in the area when treating suppurative otitis media.
