MICROBIOLOGICAL FLORA AND THEIR ANTIBIOTIC SUSCEPTIBILITY- A STUDY UNDERTAKEN WITH ENDOTRACHEAL TUBE TIPS AND ENDOTRACHEAL ASPIRATES IN A TERTIARY CARE HOSPITAL IN KOLKATA
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 25
Abstract
BACKGROUND Endotracheal (ET) tubes are life saving devices on one hand and life takers on the other. This study aims to find out how morbidity in the form of nosocomial pneumonia can be predicted to save patients and to minimise expenditure. MATERIALS AND METHODS This was a descriptive study. ET tube tips, tracheal aspirates and laryngeal aspirates were collected and tested from patients intubated for a minimum of 48 hours. 31 such samples were processed by culture in MacConkey Agar and Blood Agar media. Growth was observed. RESULTS The results showed the growth of Klebsiella Pneumoniae (54.1%) and Acinetobacter baumannii (33.3%). These findings are similar to several other studies in different parts of India e.g. by Chandra Mouli et al, Dipti Chandra et al 2017 etc. and earlier by Elek and Conen in 1957. Antibiogram by Kirby Bauer method showed that all the organisms were multidrug resistant.1,2,3,4 CONCLUSION This study reinforces the finding that ET tubes are a very important cause of pneumonia. Gram negative organisms in this study are the causative agents. Most of the organisms were sensitive to Colistin (except Proteus mirabilis, which is known to be intrinsically resistant). Moreover, the medical fraternity must be aware that on one hand the infections need immediate and correct intervention and on the other hand the resistance pattern shows that the choice of drugs is extremely limited and only the most toxic of them remain useful. Thus, the management of such cases has to be very carefully planned and balanced taking into consideration the immune status, age, co-morbidities and economic status of each patient.
