Video Double-Lumen Tube for Secondary Pulmonary Resection

Condition(s) studied

Investigational drug(s) / intervention(s)

Video Double-Lumen Tube Group: Use the video double-lumen tube to perform left bronchial intubation under real-time visualization and continuously monitor its position.

Conventional Double-Lumen Tube Group: Insert a conventional left-sided double-lumen tube using standard intubation techniques.

Study summary

During thoracic surgery, double-lumen endotracheal intubation with one-lung ventilation is routinely performed to optimize surgical exposure, facilitate operative manipulation, and prevent iatrogenic lung injury. 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.
