Abstract

Objective: To assess the frequency and antimicrobial resistance patterns of Gram-negative bacteria in burn wound infections among patients admitted to our Burns Unit.

Study Design: Cross-sectional observational study.


Setting & Duration: Department of Burns & Plastic Surgery, Ayub Teaching Hospital Abbottabad from November 2023 to April 2024.


Methodology: Fourteen patients who developed clinical signs of burn wound infections were selected purposely from a total of 150 patients. Patients with other diseases that were unrelated to the bacterial infections of burn wounds, including those with non-infected burns, or those with injuries that affected their immune system, like HIV infected patients, were also excluded from the study, to ensure emphasis was made on infections by only Gram-negative bacteria in burns.


Results: The mean age of the patients was 37.9 years, ranging from 23 to 60 years. The majority of patients (60%) were male, while females accounted for 40%. The types of burns encountered were predominantly flame burns (40%), followed by scald burns (25%), electrical burns (20%), and chemical burns (15%). The total body surface area (TBSA) burned varied significantly; with most patients (50%) having burns involving more than 25% of their body surface. The average duration of hospitalization was 17.5 days; with patients suffering from extensive burns (≥30% TBSA) requiring longer hospital stay. The microbial cultures revealed that Pseudomonas aeruginosa was the most prevalent bacterium, followed by Klebsiella pneumonia, Escherichia coli and Acinetobacter baumannii.


Conclusion: The findings of this study emphasize the importance of GN bacilli, especially Pseudomonas aeruginosa and Acinetobacter baumannii in burns wound infection implying most of the organisms as Multi Drug Resistance (MDR). The high frequency of MDR bacteria underlines the necessity for better infection measures, frequent microbial sampling and correct use of antibiotics in severe burn centers.
