To explore the related factors of cough after Uniport video-assisted thoracoscopic surgery pneumonectomy, and to provide theoretical basis and social accumulation of new knowledge for the diagnosis and treatment of cough after pneumonectomy in the future.

Intractable cough after thoracoscopic pneumonectomy is one of the common complications after pneumonectomy. The incidence of cough can reach 25% ≤ 50%. Cough after operation can aggravate the pain of incision, prolong the hospitalization time, increase the cost of hospitalization, affect the conversation and even sleep of the patients, increase the psychological burden of the patients, and reduce the quality of life of the patients accordingly. Therefore, through this study, the investigators hope to understand the related factors of cough after thoracoscopic pneumonectomy and whether there are predictable risk factors, so as to provide theoretical basis for reducing the occurrence of cough after pneumonectomy.
