The person who surveys the patient's satisfaction in the post anesthesia care unit does not know which group the patient was assigned to.
| Titration under the guidance of OAA/S | Diagnostic Test | The infusion rate of dexmedetomidine is increased by 0.1mcg/kg/h if OAA/S is greater than 3; The infusion rate is decreased by 0.1mcg/kg/h if OAA/S is less than 3. |
