Left endobronchial intubation with a double-lumen tube using direct laryngoscopy or the Trachway® video stylet Left endobronchial intubation with a double-lumen tube using direct laryngoscopy or the Trachway® video stylet

We compared direct laryngoscopy with a Macintosh blade vs indirect bronchoscopy with a Trachway^® stylet, for endobronchial intubation with a left-sided double-lumen tube. We allocated participants scheduled for thoracic surgery and who had normal predicted laryngoscopy, 30 to each group. The mean (SD) intubation times with laryngoscope and Trachway were 48 (11) s vs 28 (4) s, respectively, p < 0.001. The rates of hoarseness on the first postoperative day, categorised as none/mild/moderate/severe, were 10/12/7/1 and 22/6/2/0, respectively, p = 0.008, without differences on subsequent days. Left endobronchial intubation with a double-lumen tube is slower using direct laryngoscopy and causes more hoarseness than indirect bronchoscopy with a Trachway stylet. [ABSTRACT FROM AUTHOR]
