Video-guided Versus Conventional Right-sided Double-Lumen Tubes for One-Lung Ventilation in Thoracoscopic Surgery

This multicentre randomised controlled trial compares a video-guided right-sided double-lumen tube with a conventional right-sided double-lumen tube in adults undergoing elective thoracoscopic surgery requiring one-lung ventilation. The video-guided tube has an integrated camera that provides continuous visual feedback during placement and surgery. Participants will be randomly assigned to receive one of the two tubes. The anaesthesiologist cannot be blinded because the devices are different, but participants will not be told which tube they receive. The study will compare successful initial tube placement, tube position, the need for repositioning or fibreoptic bronchoscopy, lung collapse and surgical exposure, airway management time, and airway-related complications. The results may help determine whether continuous visual guidance improves the safety and effectiveness of right-sided double-lumen tube management.
