- Tropisetron (Type: ACTIVE_COMPARATOR): Tropisetron 5mg iv. at the start of skin closure.Sham transcutaneous electrical acupoint stimulation.Dexamethasone 10mg i.v.after induction.
- Control (Type: SHAM_COMPARATOR): Sham transcutaneous electrical acupoint stimulation. Dexamethasone 10mg i.v.after induction.
