Chi et al conducted a prospective randomized sham-control trail to evaluate the efficacy of transcutaneous electrical acupoint stimulation (TEAS) for elderly patients who received knee surgery under epidural anesthesia. TEAS on ST36, SP6, PC6, and LI11 were performed for the intervention group (n=26) out of 52 subjects. The intervention was carried out 30min prior to the epidural anesthesia and postoperative day 1 and 2, while patients in control also received sham TEAS on the same acupoints for 30min. The primary endpoint was the Quality of Recovery-40 questionnaire (QR-40) and the secondary endpoints were the biomarkers level of stress and inflammatory responses and visual analogue scale (VAS). The findings suggested that perioperative TEAS administration be able to facilitate the development of postoperative recovery of elderly patients, especially at the early stage after surgery. The mechanism is possibly attributed to the mediation by the reduction of surgical inflammation and perioperative stress response.
