In patients undergoing repeat pulmonary surgery, prior lung resection may lead to pleural adhesions and tracheobronchial distortion, which substantially increase the difficulty of bronchial intubation. Even with experienced operators, the malposition rate of conventional double-lumen tubes remains high. The video double-lumen tube enables continuous visualization of the trachea and carina during insertion, positioning, and one-lung ventilation, allowing real-time airway monitoring. However, no clinical studies have specifically investigated airway management in patients undergoing redo pulmonary surgery. This study aimed to evaluate the efficacy and safety of the video double-lumen tube during anesthesia in patients undergoing secondary pulmonary resection.",[94,95],"Lung Cancer","Pulmonary Nodule",[97,98,99,100],"First-attempt Intubation Success Rate","One-lung Ventilation","video double-lumen tube","secondary pulmonary resection","NOT_YET_RECRUITING","2026-03-09",{"date":104,"type":105},"2026-03-12","ACTUAL",{"date":107,"type":88},"2026-03-16",{"date":109,"type":88},"2027-12-05",{"name":5,"class":6},3]
