Summary
Brief summary (as posted)
Breast cancer is one of the three most common cancers worldwide, and the primary treatment method is surgery.Since most patients are non-smokers who use opioids in the postoperative period, which are known risk factors for postoperative nausea and vomiting (PONV) according to the Apfel Risk Score. Breast surgery was identified as a strong risk factor for PONV. According to the previous studies, the incidence of PONV is 30-70% in patients undergoing the breast cancer surgery, which not only gives patients unpleasant and painful experience, but also prolongs the hospital stays and delay patient discharge and adds to hospital costs. We compared the effects of dexamethasone alone vs. in combination with Pericardium 6 (P6) electrical stimulation or granisetron for inhibition of PONV in women undergoing breast cancer surgery.

- description
- a surface electrode was applied in the induction room to the P6 acupoint on the dominant upper extremity, located ∼4 cm proximal to the distal wrist crease between the tendons of the flexor carpi radialis and the palmaris longus, and a negative surface electrode on the opposing dorsal aspect of the forearm. When the patient enters the operating room， an investigator connected the device to both electrodes with electrical wires, set initial electric stimulating current at 1 mA with the frequency at 2 Hz(square-wave pulses of 0.2 ms), gradually increased the current intensity until the patient felt pain or reached the discomfort threshold (ranging from 6 to 20 mA), and maintained the stimulation until end of operation. At the start of skin closure, saline (3 ml) was administered i.v.
