Measure
Acustimulation
Transcutaneous electrical acupoint stimulation (TEAS) starts 30 min before surgery and lasts until patient leaves the postanesthetic care unit.Dexamethasone 10mg i.v. after induction. Transcutaneous electrical acupoint stimulation: A surface electrode will be applied to the P6 acupoint on the dominant upper extremity, located approximately 3cm proximal to the distal wrist crease between the tendons of the flexor carpi radialis and the palmaris longus, and a negative surface electrode placed on the opposing dorsum aspect of the forearm. Dexamethasone: will be given after induction
Tropisetron
Tropisetron 5mg iv. at the start of skin closure.Sham transcutaneous electrical acupoint stimulation.Dexamethasone 10mg i.v.after induction. Sham transcutaneous electrical acupoint stimulation: The same TEAS protocol will be applied unless silicone covers will be attached to both electrodes. The device will also be turned on during the procedure. Tropisetron: will be given at the start of skin closure Dexamethasone: will be given after induction
Control
Sham transcutaneous electrical acupoint stimulation. Dexamethasone 10mg i.v.after induction. Sham transcutaneous electrical acupoint stimulation: The same TEAS protocol will be applied unless silicone covers will be attached to both electrodes. The device will also be turned on during the procedure. Dexamethasone: will be given after induction
