Usefulness of Sputum Induction with Hypertonic Saline in a Real Clinical Practice for Bacteriological Yields of Active Pulmonary Tuberculosis

摘要

BackgroundMycobacterial identification in active pulmonary tuberculosis (APTB) is confirmative, even though successful rates using self-expectorated sputum are limited. Sputum specimens collected by hypertonic saline nebulization showed higher bacteriologic diagnostic sensitivities over those of self-expectoration, mostly studied in smear-negative or sputum-scarce patients. The efficacy of induced sputum was rarely assessed in real clinical settings.
