Background: Secondary infection from invasive devices has become great problem in Intensive Care Unit (ICU) set ups throughout the world Respiratory tract infection is an important cause of increasing mortality or morbidity with prolonged hospital stay. Against this background we studied the microbial colonization of endotracheal tube and tried to evaluate the outcome among the suspected pneumonic patients admitted in our Intensive Care Unit (ICU) Hospital. Lot of therapeutic problems occur which automatically increased mortality rate as well as cost of the treatment. This above study was designed to determine the frequency of microorganisms isolated from endotracheal tube in patients admitted in ICU of MGM Medical College and LSK Hospital, Kishanganj, Bihar from July 2009 to February 2013. Materials and Methods: Endotracheal tube aspirate samples taken from 541 suspected pneumonic patients and culture isolation of the organism were carried out. Results: The age distribution of most patients was between 65 to 85 years with the mean age of 70.7+ 10.3, all most 71% were male in comparison to 29% were female. Hospital stay time was 5-25 days with mean time 17.5 days. The median time of intubation was 6 days. The most common microorganism was Klebsiella spp. 36% Staph aureus 24%, E. coli 18%, Pseudomonas aureginosa 12%, Acinetobacter spp. 8%, Enterobacter spp. 1% and Staph. epidermidis 1%. Conclusion: There were predominance of Klebsiella and Staph aureus colonization in ET tube. However no earlier study was done in Bihar. We recommend further study among different hospitals of Bihar to determine the epidemiologic pattern of microorganism frequency.
