Description Transcutaneous electric acupoint stimulation was applied to three pairs of acupoints: bilateral Hegu (LI4); Neiguan (PC6); and Zusanli (ST36).

Auxiliary Medication
Patients in both groups received midazolam 0.03 mg.kg1 as soon as intravenous access was established. Anaesthesia was induced intravenously with fentanyl 3.0 lg.kg1 and propofol 2.0 mg.kg1. Rocuronium 0.5 mg.kg1 was given to facilitate laryn- geal mask airway (LMA) insertion. Anaesthesia was maintained with target-controlled infusions of propofol and remifentanil. The anaesthesiologist adjusted the effect-site concentration of propofol and remifentanil according to the haemodynamics and bispectral index.

Description The acupuncturist carried out this stimulation using a dense-disperse frequency of 2/10 Hz with an intensity of 6–9 mA for 30 min using the Hwato electronic acupuncture treatment instrument (model No. SDZ-V; Suzhou Medical Appliances Co., Ltd., Suzhou, China). The optimal intensity was adjusted to maintain a slight twitching of the regional muscle according to individual maximum tolerance. In the sham group, the patients were connected to the instrument, but electronic stimulation was not applied.

Effector
We found significant mean (SD) differences between the transcutaneous electric acupoint stimulation and sham groups in the mean (SD) length of recovery room stay (35.6 (12.9) min vs 48.3 (16.3) min, p = 0.01), time to removal of the laryngeal mask airway (10.2 (2.5) min vs 17.8 (4.4) min, p = 0.01), and time to reorientation of the patient (14.6 (3.2) min vs 26.5 (5.0) min, p = 0.01). Further, postoperative pain scores and the incidence of side-effects were all lower in the transcutaneous electric acupoint stimulation group.

Abstract
Electroacupuncture has been demonstrated to be effective at alleviating pain and postoperative side-effects. Our aim was to investigate whether transcutaneous electric acupoint stimulation, a low-skill alternative to needle-based electroacupuncture, could improve the quality of recovery after ambulatory surgery. Seventy-two women scheduled for cosmetic breast surgery were randomly allocated to transcutaneous electric acupoint stimulation or sham groups. Patients in the transcutaneous electric acupoint stimulation group received 30 min of electrical stimulation at three acupoints located on the hand and forearm before the induction of general anaesthesia. We found significant mean (SD) differences between the transcutaneous electric acupoint stimulation and sham groups in the mean (SD) length of recovery room stay (35.6 (12.9) min vs 48.3 (16.3) min, p = 0.01), time to removal of the laryngeal mask airway (10.2 (2.5) min vs 17.8 (4.4) min, p = 0.01), and time to reorientation of the patient (14.6 (3.2) min vs 26.5 (5.0) min, p = 0.01). Further, postoperative pain scores and the incidence of side-effects were all lower in the transcutaneous electric acupoint stimulation group. In conclusion, transcutaneous electric acupoint stimulation can significantly improve the quality of recovery and decrease the incidence of anaesthesia-related side-effects for patients undergoing ambulatory surgery."
