Study Phase: Not Applicable
SUMMARY

The goal of this clinical trial is to assess the impact of laryngeal mask combined with visual bronchial blocker on pharyngolaryngeal injury after pulmonary resection in patients with pulmonary nodules. The main question it aims to answer is: the incidence of postoperative pharyngolaryngeal injury within 24h : sore throat and hoarseness ? Researchers will compare the visual bronchial blocker group (VBB) with the double-lumen endotracheal tube group (DLT) to see if the visual bronchial blocker group can minimize laryngopharyngeal injury after pulmonary resection.
