Abstract
Objectives: To determine the frequency of Methicillin-Resistant Staphylococcus Aureus in patients referred from other specialities to plastic surgery unit at lady reading hospital, Peshawar and to document its current antimicrobial sensitivity
and resistance pattern.
Material and Methods: Over a three months period a descriptive cross-sectional study was conducted including all patients with infected wounds referred to plastic surgery and burns unit lady reading hospital Peshawar, from December 2012 to March 2013, for the purpose of various plastic procedures. Swab specimens taken from wound sites were sent for microbial culture, and their antimicrobial sensitivity and resistance testing was done.
Results: Out of a total of 144 cases included in the study, the frequency of culture positive cases was 84 (58.3%), of which the frequency of MRSA was 51 (60.71%). The frequency of culture negative cases was 60(41.7%). All the MRSA showed 100% sensitivity to linezolid, teicoplanin and vancomycin. The MRSA obtained was 100% resistant to major groups of antibiotics.
Conclusion: Our study showed a significant number of MRSA as a cause of wound infection, which may have been contracted during dressing exercises. The majority of these MRSA are now resistant to the commonly prescribed antibiotics.
