This study intends to explore a new therapy to reduce the incidence of atrial fibrillation in thoracic patient who receive video-assisted thoracoscopic lobectomy .The results of the study are to assess the effects of this new intervention on the incidence，duration of atrial fibrillation and other complications including postoperative delirium after video-assisted thoracoscopic lobectomy .And reducing the burden of POAF on patients and their families, hospitals and public resources.

| topical local anesthesia of pulmonary vein combined with vagus nerve block | Procedure | Injecting 1% lidocaine 1.5ml+0.375% ropivacaine 1.5ml into vascular sheaths of all pulmonary vein of the surgery side at the beginning of surgery operation. Wrapping all pulmonary vein of the surgery side with cotton sheet infiltrated with 1% lidocaine+0.375% ropivacaine at the end of surgery operation. Blocking vagus nerve above the aortic vein on the right side of the trachea with 1% lidocaine 1ml+0.375% ropivacaine 1ml after exposing the pleural apex. |
