Antimicrobial resistance of bacterial isolates from respiratory secretions of ventilated patients in a multi-specialty hospital
Context: Ventilator-associated pneumonia (VAP) is a common nosocomial infection occurring in intensive care unit (ICU) settings. VAP occurs due to interplay of three factors - impaired host defense, access of large numbers of pathogenic bacteria to the lower respiratory tract and the virulence of th...

Subjects and Methods: A prospective study was performed over a period of 6 months in a multi-specialty hospital to determine the various pathogens in respiratory secretions and to determine the prevalence of multidrug resistance (MDR). Results: Pseudomonas aeruginosa (26%), Acinetobacter (26%), Klebsiella pneumoniae (26%), followed by Escherichia coli (15%), Staphylococcus aureus (6%) and Citrobacter spp. (1.5%) were the common pathogens isolated in our study. In all, 72.73% (48/66) bacterial isolates were isolated from medical ICU, while 25.76% (17/66) were isolated from surgical ICU. Only one strain (Acinetobacter) was isolated from pediatric ICU.

Conclusion: There is increasing colonization of pathogenic bacteria in ventilated patients admitted in ICUs, which are predominantly MDR. These colonizers may cause infection resulting in VAP. Judicious use of antibiotics, guided by local antibiotic resistance profile coupled with strict infection control practices alongside application of VAP bundle are important measures to prevent these pathogens from causing VAP in ICU patients.Nishat Hussain AhmedTabish HussainIndu BiswalThieme Medical and Scientific Publishers Pvt.
