Bacteriology of nosocomial pneumonias in patients on mechanical ventilation

Abstract :

 Introduction: Eighty–six percent of nosocomial pneumonias are associated with mechanical ventilation (MV). It is commonest complication in ICU patients reported at the rate of 1–3% per day of MV in tertiary care hospitals. In spite of the advances in the diagnosis, treatment and prevention, it continues to be a major cause of morbidity and mortality among critically ill patients. Objectives: To isolate bacterial pathogens causing VAP and determine their antimicrobial susceptibility. Materials and Methods: A prospective study was conducted in the Department of Microbiology, Government Medical College & Hospital, Amritsar over a period of one and a half year for patients admitted in ICU who required mechanical ventilation and who fulfilled both clinical and microbiological criteria for VAP. The respiratory specimens were collected under aseptic conditions and transported immediately to the laboratory and processed in the Microbiology laboratory by standard microbiological procedures. All the isolates were further identified by biochemical tests and their antimicrobial susceptibility was determined. Results: Out of total patients, the most common organisms isolated were Acinetobacter spp (33.33%) and Pseudomonas spp (30.23%) followed by Staphylococcus spp (13.95%) Klebsiella spp (11.62%), Escherichia coli (6.20%), CONS (3.10%) and Citrobacter spp (1.55%). Conclusions: Mechanical Ventilation is a life saving intervention, it has its own potential complications. Early, accurate diagnosis is, therefore, fundamental in patients with VAP.
