A Retrospective study on ICU isolates on Tracheostomy tube and their antimicrobial profile
Keywords:Ventilated patients, Multi Drug Resistant (MDR), Antibiogram.
Introduction: The tracheostomized patients are likely to develop pneumonia causing life threatening consequences due to severe, persistent, resistant infections. Objective: This study was done with the aim to identify the common organisms which cause Respiratory Tract Infections (RTI) and their resistant pattern of ventilated patients in Intensive Care Unit (ICU). Methods: This retrospective study was conducted on the patients who underwent tracheostomy in ICU of Government Medical College, Jammu. The samples were processed according to established departmental protocols. Results: Out of 54 samples, 50(93%) were culture positive. 6samples were found to be polymicrobial. 4 samples showed no growth. Citrobacter sp., Escherichia coli, Pseudomonas sp. being the commonest species isolated. Citrobacter sp. and Klebsiella sp., Proteus sp. and Staphylococcus aureus showed high degree of resistance while Pseudomonas sp. and Escherichia coli showed moderate resistance. The gram negative bacilli were all sensitive to Colistin and Polymixin B. Staphylococcus aureus was 100% sensitive to Vancomycin. Conclusions: Intubated patients are the risk factor for development of RTI and to the increase in morbidity and mortality. Inappropriate and inadequate antibiotic treatment causes emergence of drug resistance in pathogens and poor prognosis in patients. The study reported the alarming condition of MDR in tracheal aspirates. Hence, surveillance for source of Multi Drug Resistant bacteria would be beneficial for intervention of infection related to it.
