Abstract
Background: Ventilator associated pneumonia (VAP) is a major cause of higher morbidity and mortality among hospitalized patients especially in the Intensive Care Unit (ICU).
Objective: This study was conducted to explore the bacterial pathogens among ICU patients with Ventilator Associated Pneumonia (VAP).
Methods: This was a descriptive type of cross sectional study conducted during the period of twelve months (January to December 2018) among clinically suspected VAP patient admitted in Intensive Care Unit at Rajshahi Medical College and Hospital. A total of 80 endo-tracheal aspirate (ETA) samples were collected purposively from clinically suspected VAP cases during study period.
Results: Among the respondents males were 48 (60%) and female were 32 (40%). Maximum 20% cases were within age group of 21-30 years. Majority of the patients were admitted with primary diagnosis of head injury (36.25%) followed by stroke (26.25%). Among 80 ETA samples, 75 (93.75%) samples were culture positive. Out of 75 culture positive cases 72(96.0%) were single isolates and 3(4.0%) were multiple isolates. Among the total 78 isolates were identified higher gram negative organisms (74.36%) than that of gram positive (25.64%). Moreover, among 78 isolates, Pseudomonas aeruginosa were the predominant 35.9%.
Conclusion: VAP was an important nosocomial infection among ICU patients receiving mechanical ventilation and most of cases gram negative organism are responsible for this infection.
