Airway management for one-lung ventilation in thoracic surgery
Conditions
Interventions
Group 1 Name: NRL Group (Non-Rotational Intubation Group):Intervention: In the lateral decubitus position, a NORGAS left-sided video double-lumen endobronchial tube (VDLT) is inserted using the non-r
2.The tracheal lumen is straightened at the proximal segment
3.A "J-shaped" bend (approximately 75°) is formed from the camera tip to the white bronchial cuff, mimicking the curvature of a standard single-lumen endotracheal tube, to facilitate direct advancemen
Group 2 Name: TRL Group (Traditional Rotational Intubation Group):Intervention: In the lateral decubitus position, a NORGAS left-sided video double-lumen endobronchial tube (VDLT) is inserted using t
2.After passing the vocal cords, the stylet is removed, and the tube is rotated 90° counterclockwise before advancing to the carina.
All intubations will be performed by the same senior anesthesiologi
