Background: To ascertain the bacteriological profile of patients with nosocomial pneumonia in endotracheal cultures and correlation with blood cultures. Methodology: 559 endotracheal aspirates were collected using mucous traps from 180 patients of suspected nosocomial pneumonia patients over 2 years. The samples were processed and a colony count of 104cfu/ml was taken as the cut-off to differentiate between pathogens and colonizers. Identification and sensitivity of bacterial isolates was done with the help of Vitek 2. Blood for culture was processed as per standard techniques. Results & Conclusion: Klebsiella sp.(33%) was the commonest bacteria isolated, followed by Acinetobacter baumanii, Pseudomonas sp., Escherichia coli and Staphylococcus aureus. 25% of Acinetobacter spp. and 40% of Pseudomonas spp were pandrug resistant. Mostly non-fermenters were sensitive to Tigecycline and Colistin. Enterobacteriaceae showed highest resistance for Cephalosporins and Cotrimoxazole but were mostly sensitive to Tigecycline. Staphylococcus aureus was uniformly sensitive to Linezolid and Teicoplanin. Blood cultures were positive in 52 (9.3%) patients of which pulmonary origin bacteremia was present in 33 patients while non-pulmonary origin bacteremia was present in 19 patients. The pulmonary care bundle along with rational use of antibiotics will go a long way to improve treatment outcome, patient morbidity and mortality. [Tiwari U NJIRM 2016; 7(3):60 - 63]
