AbstractIntroduction: Surgical site infections are among the most common complications of inpatient admissions and have serious consequences for outcomes and costs. Different risk factors may be involved, including age, sex, nutrition and immunity, prophylactic antibiotics, operation type and duration, type of shaving, and secondary infections Methodology: In the microbiology department, the swabs were inoculated onto blood agar plate, McConkey’s agar plates and nutrient broth. Inoculated media were incubated aerobically at 37°C for 24-48 hrs. Nutrient broth was sub cultured if the original plates did not yield organisms. The bacteria isolated were identified by their morphological and cultural characteristics. Results: E-coli cause 86.6% of infection upto 5 days pre op hospitalisation and pseudomonas causes 60% infection in the same period. Klebsiella causes 75% of infection in 6 -10 days pre op period. During >10 days period staphylococcus. Conclusion: Apart from this regular review and monitoring of the implementation of guidelines is equally important.
