Abstract
VAP is one of the serious complications that occur at ICU. As its causative pathogens are antibiotic resistant in many cases, it is difficult to select appropriate antibiotics. The causative pathogens of VAP may vary depending on country, region, and hospital. Therefore, the diversity of the microbial flora in VAP & knowing their susceptibility pattern is very important in the prevention of VAP. 96 patients who were under mechanical ventilation for more than 48 hours by endotracheal tube or tracheostomy were evaluated. Endotracheal sampling was cultured, and pathogens were isolated. It was also observed that the mortality rate was 20.83% (20 out of 96 patients). 108 pathogens were isolated, and it was found that 12 patients had co infection with 2 organisms. Out of 108 isolates, 28(25.92%) were Pseudomonas aeruginosa, 21(19.44%) were Klebsiella pneumoniae, 17(15.74%) were Staphylococcus aureus, 8(7.4%) were Acinetobacter species, 7(6.48%) were Coagulase negative Staphylococcus, 6 (5.55%) were Proteus mirabilis, 5 (4.62%) Escherichia coli, 5 (4.62%) were Candida species and 5 (4.62%) was Enterobacter sp. Almost all the Pseudomonas aeruginosa, Acinetobacter sp & Klebsiella pneumoniae were multidrug resistant and all the Staphylococcus aureus and CoNS were Methicillin resistant. Prompt and early diagnosis of pneumonias would be the mainstay in bringing down mortality rate in Ventilator associated Pneumonia.
