The video-guided tube incorporates an integrated camera that provides continuous airway visualisation during initial placement and intraoperative monitoring.\n\nParticipants will be randomly assigned in a 1:1 ratio to receive one of the two tubes. Final tube position after initial placement will be confirmed by fibreoptic bronchoscopy in both groups. During one-lung ventilation, additional fibreoptic bronchoscopy will be performed only when clinically indicated or according to predefined rescue criteria.\n\nThe primary outcome is successful initial right-sided double-lumen tube placement. Secondary outcomes include right upper-lobe bronchial obstruction, intraoperative tube displacement, hypoxemia during one-lung ventilation, requirement for rescue fibreoptic bronchoscopy, time to satisfactory tube positioning, quality of operative lung collapse, and the number of intraoperative tube repositioning events.\n\nParticipants and outcome assessors will remain blinded to treatment allocation, whereas the anaesthesiologist performing intubation cannot be blinded because of the distinct visual and operational characteristics of the two devices. The study aims to determine whether continuous airway visualisation improves the effectiveness and stability of right-sided double-lumen tube management during thoracoscopic surgery.",[95,96,97],"Thoracoscopic Surgery","Double Lumen Tube Intubation","One-Lung Ventilation",[9,99,100,101,102,103],"Right-sided double-lumen tube","One-lung ventilation","Fibreoptic bronchoscopy","Thoracoscopic surgery","Lung isolation","2026-08-13",{"date":106,"type":107},"2026-08-17","ACTUAL",{"date":109,"type":107},"2026-05-30",{"date":111,"type":89},"2027-03-01",{"name":68,"class":6},3]
