干预措施代码:

Intervention:

Lateral position direct visualization bronchial blockade intubation: After entering the operating room, establish intravenous access and induce anesthesia with midazolam 0.05 mg/kg, sufentanil 0.5 μg/kg, propofol 2 mg/kg, and rocuronium 0.6 mg/kg; position the patient in lateral decubitus (healthy side down, affected side up); insert a 7.0–7.5 mm endotracheal tube via oral route using a video laryngoscope, then advance a visualized bronchial blockade catheter through the endotracheal tube under real-time visualization until the tip reaches the orifice of the affected main bronchus, confirm correct positioning, inflate the cuff (pressure 15–25 cmH2O), and secure the tube.

干预措施:

传统仰卧位插管:术前准备与麻醉诱导同试验组,患者保持仰卧位;由同资质医师采用可视喉镜引导,先插入 7.0-7.5 号气管导管,再插入可视封堵支气管插管,可视化监测将封堵支气管插管前端送至患侧主支气管开口处,确认位置准确后固定导管;随后调整体位为侧卧位。

干预措施代码:

Intervention:

Conventional supine position intubation: Preoperative preparation and anesthesia induction are the same as in the trial group; maintain the patient in supine position; a qualified physician performs intubation using a video laryngoscope, first inserting a 7.0–7.5 mm endotracheal tube, then advancing a visualized bronchial blockade catheter under real-time visualization to position the tip at the orifice of the affected main bronchus, confirm correct placement, secure the tube, and then reposition the patient into lateral decubitus.
