ABSTRACT

Objectives: To analyse the risk factors, severity pattern of infectious wounds and to analyse the antimicrobial sensitivity patterns. Methods: A prospective study, conducted for a period of 5 months, from November 2015 to March 2016. 138 wounds with pus were included. A Predesigned data collection form including demographic details, diagnosis, severity assessment scale, antibiogram report, medication chart was used. Results: Infectious wounds were found to be more prevalent in males (71.01%) than females (28.98%). A total of 124 cases with positive cultures were obtained. The major risk factor was found to be Diabetes mellitus (57.24%) followed by Hypertension (22.26%). Moderately severe infections were observed mostly (50.72%) followed by severe infections (43.47%). The infections were predominantly due to gram negative bacteria (54.03%) than gram positive bacteria (45.96%). The commonest isolates among the gram negative bacteria’s were, Escherichia. coli (25.36%) and Pseudomonas aeruginosa (14.49%). Among the gram positive bacteria, Staphylococcus aureus was predominant (70.17%). E.coli was mostly sensitive to Amikacin (74.28%) and resistant towards Amoxicillin (51.42%). S.aureus was found to be sensitive to Vancomycin (55%) and was resistant towards Cotrimoxazole (32.5%). Conclusion: This study showed a preponderance of gram negative bacilli among the isolates from the infectious wounds. Most of the microorganisms showed resistance to commonly used antibiotics like Cotrimoxazole and Amoxicillin. This underscores for periodic surveillance of etiologic agent and antibiotic susceptibility to prevent further emergence and spread of resistant bacteria pathogens.
