To assess the role of sputum induction using levosalbutamol nebulisation in patients having dry cough of 3 weeks or more in the bacteriological diagnosis of pulmonary TB.
In the study, 50 patients were included presenting with dry cough of 3 weeks or more suggestive of pulmonary TB. Sputum induction was performed using levosalbutamol nebulization. The induced sputum was stained with Ziehl Neelson staining method and examined for Mycobacterium tuberculosis.
Out of total 50 patients having dry cough, the sputum induction was successful in producing adequate specimen in 22 (44%) cases (x2 = 28.263; p < 0.001). Out of these 22 cases, 10 were found to be sputum smear positive for AFB. Thus in 10(45%) cases bacteriological diagnosis could be confirmed.
The bacteriological confirmation could be achieved in higher number of cases, false negativity rate can be decreased & time taken by laboratory technician to declare positive slide can be reduced.
Sputum induction using levosalbutamol nebulization is a safe, economical method, not requiring much of expertise and can be used in field conditions, for confirmation of diagnosis of patients presenting with dry cough.
