Clinical Trial Summary

Currently, there is a trend toward non-intubated anesthesia methods for video-assisted thoracic surgery in our hospital. During the surgery, intrathoracic vagus nerve blockade is suggested for inhibit cough reflex in previous paper. However, right and left side of vagus nerves both deep near the aorta or trachea respectively. To achieving the procedure may induce cough reflex by lobar traction even result vital organ damage. This study aims to apply alternative vagus nerve blockade at neck level via ultrasound guidance and test if the procedure real reduce cough reflex then previous method. We also follow up the patient's vital sign, vocal cord and diaphragm movement, horner syndrome and hoarseness to evaluating if cervical vagal blockade has the potential risk involve other surrounding nerves
