Objective To evaluate the clinical application of thoracoscope mediastinal tumor resection with the laryngeal mask anesthesia. Methods 40 cases of mediastinal tumors were randomly divided into two groups from 2012 to 2015, 20 cases in each group. Laryngeal mask group performed thoracoscope mediastinal tumor resection with laryngeal mask anesthesia and the Intubation group performed thoracoscope mediastinal tumor resection dou-ble-lume nendo tracheal intubation anesthesia, then compare the overall effect. Results All the patients were suc-cessfully completed with the thoracoscope surgery, no transfer to open chest cases. The preoperative anesthesia time of laryngeal mask group was shorter, blood pressure and pulse range of wave was smaller in the process of anesthesia and surgery, move restlessly was less, postoperative recovery time was shorter, and lower incidence of postoperative pharynx ministry unwell and sore throat, so the laryngeal mask group shows statistically significance comparing with the intubation group (P < 0.05); Operative time, operative field exposure satisfaction, intraoperative blood loss, post-operative extubation time and hospitalization days have no statistical significance (P >0.05). Conclusion The laryn-geal mask airway intravenous anesthesia in thoracoscope mediastinal tumor resection in practical good, in the preop-erative anesthesia and postoperative recovery time and postoperative sore throat was better than that of intubation group, so should be extended in clinical treatment.

Objective To evaluate the feasibility and safety of thoracoscopic lung cancer surgery under non-tracheal intubation anesthesia. Methods Twenty patients with peripheral lung cancer were enrolled in experimental group and control group. Then monitored and recorded Systolic pressure (SBP), diastolic pressure (DBP), mean arterial pressure (MAP), heart rate (HR), electrocardiogram (ECG), heart rate (HR), Oxygen saturation (SpO2), Final moisture CO2 partial pressure (PETCO2), central venous pressure, invasive arterial blood pressure and blood glucose and the related complications like sore throat, hoarse voice, nausea and so onin such time points: before induction (T0), induction of intubation (T1), operation (T2), and sudden removal (T3) of the two groups. Results The laryngeal mask group was given a smaller stimulus to the cardiovascular system during anesthesia.The time of feeding, the exhaust, the time of getting out of bed, the average hospitalization day, the reduction of hospitalization expenses, pharynx, respiratory and cardiovascular complications were shorter and less than intubation group. Conclusion The laryngeal mask ventilation intravenous anesthesia with thoracic vagal nerve block in the thoracoscopic lobectomy is simple, safe, no intubation-related complications and single lung ventilation lung injury, in line with surgery -anesthesia overall minimally invasive development concept, worthy of clinical promotion.
