Our Institutional Antibiogram; the Insight Gained in Selection of Empirical Antibiotics for the Treatment of Burn Wound Infection.

Objectives: The aim is to study the prevalence of bacteria involved in burn wound infection and the antibiotic susceptibility patterns of these bacteria. Methodology: It was a cross-sectional, descriptive, observational study conducted in Burns and Plastic Surgery Center for six months. Sampling was done using a consecutive non-probability method for antibiogram construction. A summary of isolated bacteria's antibiotic susceptibilities to tested antibiotics and the prevalence of isolated species and genera of bacteria in percentages was determined by analyzing wound culture and susceptibility reports of burn wound clinical samples to construct an antibiogram. Results: Collectively, the gram-negative bacilli (79.13%) and individually Klebsiella pneumonia (P.pneumonia) (23.33%), Pseudomonas aeruginosa (P.aeruginosa) (22.94%) and Staphylococcus aureus (S. Aureus) (14.55%) were most common respectively. The highest susceptibilities by all isolates were shown to carbapenems, piperacillin/tazobactam, and amikacin. Conclusion: Gram-negative bacteria of Enterobacteriaceae family i.e. K.pneumoniae and Enterobacter spp. along with P.aeruginosa and gram-positive cocci were the most prevalent organisms isolated.
