Intervention group
Blank control group
In addition to routine anesthesia management and surgical operations, a stellate ganglion block was performed before induction of anesthesia, and then receive standard care after operation. Related statistical indicators were collected prospectively.
In this study, a blank control was used. Routine anesthesia management and surgical operation were used without any special interventions(only an camouflaging action), and then receive standard care after operation. Only relevant statistical indicators were collected prospectively.
