The pattern of Microbiological Colonization of Endotracheal Tube Aspirate on Mechanically Ventilated Patients: A Clinical Study from central India

Abstract

Background: Among intubated patients, nosocomial infection is a serious problem that contributes significantly to their morbidity and mortality. Pneumonia, a common complication of the endotracheal tube and mechanical ventilation, is one of the most important types of this infection. Aims and objectives: To study the antibiotic sensitivity patterns for the most common microorganisms isolated from the endotracheal tubes of hospitalized patients. Materials and Methods: Patients admitted to Hamidia Hospital's emergency medical ward and then intubated and assisted by mechanical ventilation due to insufficient self-ventilation were studied. For microbiological cultures and sensitivity tests, specimens were collected 48 hours after intubation using a mucous extractor and sent to the Microbiology Laboratory for processing. Results: During our study, we found that 25 percent of our patients had Ventilator-associated pneumonia. Pseudomonas aeruginosa accounts for 17 percent of positive sputum cultures, followed by klebsiella (6%) and staphylococcus aureus (2%). Conclusion: Pseudomonas was the most common organism found, followed by klebsiella and staphylococcus aureus, and the majority of the organisms were susceptible to piperacillin-tazobactam and meropenem.
