Background: Ventilator Associated Pneumonia is a common infectious disease that is found in intensive care unit (ICU), which occurs in 8-38% of patients who underwent mechanical ventilation. The study was conducted to find the Bacteriological Profile of Ventilator Associated Pneumonia and the antibiotic sensitivity pattern of the isolates.
Materials & Methods: A total of 84 bacterial isolates from 98 clinically suspected adult patients with VAP, who were admitted to the medical and surgical intensive care unit from January 2013 to December 2013 were examined. Clinical characteristics, bacterial pathogens, and resistance profiles were analyzed.
Results: Klebsiella spp. (23.80%) was the most common isolate that was identified. The other significant Gram negative isolates implicated were E. coli, Pseudomonas aeruginosa, Acenitobacter baumanii. Amongst the gram positive isolates Staphylococcus aureus (15.47%) was most frequently isolated from the transtracheal aspirates or bronchoalveolar lavage in patients with VAP. There was no significant difference of bacterial pathogens between early and late onset VAP.
Conclusion: The two most frequent pathogens of VAP were Klebsiella spp. and S. aureus. There were no pathogenic differences between early and late onset VAP.
