Abstract Background Double-lumen tube (DLT) intubation is necessary for thoracic surgery and other operations with the need lung separation. However, DLT insertion complex might result in airway trauma. A new videolaryngoscopy (GVL) a thin blade improve time reduce complexity as well iatrogenic complications compared to conventional direct laryngoscopy (DL) intubation. Methods randomised, controlled trial was conducted 70 patients undergoing elective using Primary endpoint successful The secondary endpoints of this study were number attempts, assessment difficulty, any during incidence objective trauma oropharynx supraglottic space intubation-related subjective symptoms. Results 65 included (DL group [ n = 31], GVL 34]). Median (25th–75th percentiles) 93 s (63–160) versus 74 (58–94) DL p 0.044]. resulted significantly improved visualisation larynx (Cormack Lehane grade 1 97% vs. 74% Group 0.008]). Endoscopic examinations revealed significant differences showing less red-blooded vocal cord 0.004], haematoma 0.022] haemorrhage 0.002]. No regarding postoperative symptoms found. Conclusions Videolaryngoscopy GlideScope®-Titanium shortly prolongs duration but improves view. Objective not complaints are reduced.
