Abstract :

Background: Ventilator–associated pneumonia (VAP) is a major cause of hospital morbidity and mortality despite recent advances in diagnosis and accuracy of management. However, as taught in medical science, prevention is better than cure is probably more appropriate as concerned to VAP because of the fact that it is a well preventable disease and a proper approach decreases the hospital stay, cost, morbidity and mortality. Aims: The aim of the study was to study the prevalence of ventilator associated pneumonias in intensive care unit, to identify the type of micro–organisms & to study the antibiotics sensitivity of these micro–organisms. Methodology: The present study comprised of 60 patients admitted in surgical intensive care unit as well as medical intensive care unit who were on ventilator for different reasons. The patients were treated appropriately according to antibiotic sensitivity. CPIS–clinical pulmonary infection score was recorded. Results: the incidence of VAP was more common in men (68.3%) then female (31.7%). The occurrence of VAP was more common in the age group of 36–45 years (26.7%). 25 % patients were catagorised under early onset VAP and 75% under late onset VAP. Mode of airway in 93.3% patients was endotracheal route whereas only 6.7% patients were tracheostomised. 28.33 % patients developed VAP who were diagnosed as stroke with hypertension. Acinetobacter Spp and Klebsiella were the commonest isolates obtained in both early and late onset VAP. Piperacillin and Tazobactum was sensitive in 46.7% cases and Ciprofloxacin was the most resistant (40%) antibiotic. Conclusion: In conclusion the present study showed a gradual increase in VAP along with the duration of stay in ICU. Most of the affected patients were in 4^th decade with male predominance. Acinetobacter Spp (45%) was the most prominent pathogen that was responsible for VAP. Piperacillin with Tazobactum was sensitive among 46.7% of the cases where as Ciprofloxacin was the most resistant antibiotic
