Videolaryngoscopes are widely used to visualize difficult airways. Our aim was to compare the GlideScope and C-MAC D-blade videolaryngoscopes for double-lumen tube (DLT) intubation in patients with difficult airways. A multi-center, prospective, randomized controlled trial. Three comprehensive tertiary, high-volume hospitals from 5 December 2020 to 4 November 2021. We included 348 adult patients with anticipated difficult airways who underwent elective thoracic surgery. Patients were randomized into two groups: GlideScope and C-MAC D-blade. Following anesthesia induction, DLT intubation was performed using different videolaryngoscopes. The primary outcome was the first-pass success rate of DLT intubation. All other results were recorded as secondary outcomes. No significant differences were observed in the first-pass success rate of DLT intubation between the GlideScope and C-MAC D-blade (86.21% and 89.66%, respectively; P = 0.323). However, compared with the GlideScope, the C-MAC D-blade provided a lower Cormack–Lehane grade (P
