administration of 0.5 ug/kg of dexmedetomidine and dexamethasone 5mg (total 5ml)
Outcomes
Primary Outcome Measures
Postoperative Nausea (Numeric Rating Scale for Nausea)
Numeric rating scale for postoperative nausea (scores on a scale) (0-no symptoms; 10-worst symptoms imaginable). Ramosetron 0.3 mg was administered to patients with nausea >5 points on the numeric rating scale
Secondary Outcome Measures
Postoperative Vomiting (Number of Participants With Vomiting)
frequencies of vomiting (number of participants with vomiting) 24 hour post-operatively
Rhodes Index Score
Rhodes Index of nausea, vomiting, and retching at 6 to 24 hours after surgery (ask 8 question about discomfort due to PONV and each questions are consist of 0~4 score) (minimal PONV 0 to maximal PONV 32) lower values represent a bettwer outcome

5. Study Description
Brief Summary
Previous reports demonstrated that dexmedetomidine could reduce the incidence of postoperative nausea and vomiting (PONV). Dexamethason also had been commonly used for ajuvant drugs for preventing and reducing PONV. So investigator want to study about the effect of dexmedetomidine only or combined with dexamethasone for preventing PONV.
