This study aims to systematically evaluate the effects of different anesthesia methods on postoperative chronic cough in lung cancer patients undergoing video-assisted thoracoscopic lung resection (VATS), and to clarify the effectiveness and safety of each anesthesia airway management strategy in reducing the incidence of postoperative chronic cough, shortening the duration of cough, alleviating the severity of symptoms, and improving the postoperative quality of life of patients.
