the Clinicaltrail of the Effection Which of Phrenic Block Using in Non-intubated Video-assisted Thoracoscopic Surgery

Early Phase 1UnknownNCT03653494

Shenzhen People's Hospital80 enrolled

Overview

Putting 80 patients divided into group S（non-intubated general anesthesia combine with Paravertebral blocks、surface spray anesthesia and Vagus block） and group D（non-intubated general anesthesia combine with Paravertebral blocks、surface spray anesthesia、Vagus block and Phrenic block）randomly,compare the volume of anesthetic and the number of increasing anesthetic during operation were compared between the two groups.If the date of group S greater than group D，it shows that the effect of anesthetic effect of group D is better than group S.

1. Put 80 patients divided into group S（non-intubated general anesthesia combine with Paravertebral blocks、surface spray anesthesia and Vagus block） and group D（non-intubated general anesthesia combine with Paravertebral blocks、surface spray anesthesia、Vagus block and Phrenic block）randomly. 2. Compare the volume of anesthetic drugs between the two groups. 3. If the date of group S greater than group D，it shows that the effect of anesthetic effect of group D is better than group S.
