Summary
Brief summary (as posted)
Right-sided double-lumen tubes are used for lung isolation during thoracoscopic surgery but can be difficult to position because of right bronchial anatomy. This multicenter randomized controlled trial will compare a continuous video-guided right-sided double-lumen tube with a conventional right-sided double-lumen tube in adult patients undergoing thoracoscopic surgery requiring right-sided lung isolation. The primary objective is to determine whether continuous video guidance increases the rate of successful initial right-sided double-lumen tube positioning. Secondary outcomes include positioning time, clinically relevant intraoperative tube displacement, rescue fiberoptic bronchoscopy, lung collapse quality, hypoxemia during one-lung ventilation, and airway-related complications.

Primary outcomes (1)
- measure
- Number of participants with successful initial right-sided double-lumen tube positioning assessed by fiberoptic bronchoscopy
- timeFrame
- Intraoperatively, immediately after initial tube positioning and before initiation of one-lung ventilation.
- description
- Successful initial positioning is defined as Grade 1 (optimal) or Grade 2 (acceptable) tube position at the first protocol-mandated fiberoptic bronchoscopic assessment before any bronchoscopic adjustment. Grade 3 (malposition) is considered unsuccessful. Successful positioning requires an acceptable bronchial cuff position, adequate alignment of the right upper-lobe ventilation slot with the right upper-lobe bronchial orifice, absence of clinically relevant right upper-lobe obstruction, and a patent bronchus intermedius without the need for further advancement, withdrawal, or rotation of the tube. Each participant will be classified as successful or unsuccessful.
