Abstract :

Intensive care unit (ICU) patients are most vulnerable for developing respiratory and urinary tract infections especially who are mechanically ventilated due to complex interplay between the endotracheal tube, host immunity and virulence of invading bacteria. We analyzed the bacteria and their antibiotic sensitivity pattern isolated from endotracheal aspirates of ventilated patients in ICU.The prospective study was done with the endotracheal samples received in the Microbiology Laboratory in a tertiary care hospital over a period of one year. Samples were collected under sterile conditions from medical and surgical ICU patients who were ventilated for at least 48 hrs. The samples included endotracheal secretion and endotracheal tube tip which was processed as per microbiological standards.A total of 90 samples from 90 patients were collected during the study period of one year. The two major reasons for admission were organophosphate poisoning and RTA with head injury. There was predominance of male patients with M: F ratio of 3:1 respectively. The organisms commonly isolated were Klebsiella Pneumoniae (72),Sphingomonas paucimobilis (3),Acinetobacter baumani (5), Pseudomonas aeruginosa (5),Candida albicans (2),Proteus mirabilis (2), and Staphylococcus aureus. Out of 90 isolates 45 were multi-drug resistant which implies that 50% of isolates are multidrug resistant. Regular periodic surveillance of microbial profile and susceptibility patterns of ventilated patients in ICU should be done to detect emerging resistant bacterial strains.
