Background Multimodal opioid‐sparing analgesia is a key component of an enhanced recovery pathway after surgery that aims to improve postoperative recovery. Transcutaneous electrical acupoint stimulation (TEAS) is assumed to alleviate pain and anxiety and to modify the autonomic nervous system. This study aimed to determine the efficacy of TEAS for sedation and postoperative analgesia in lung cancer patients undergoing thoracoscopic pulmonary resection. Methods A total of 80 patients were randomized into two groups: the TEAS group and the sham TEAS combined with general anesthesia group. Postoperative pain levels at six, 24, 48 hours, and one month after surgery were measured using the visual analogue scale (VAS). Bispectral index (BIS) score during the TEAS prior to anesthetic induction, Observer's Assessment of Alertness/Sedation (OAAS) score, sufentanil consumption during postoperative patient‐controlled intravenous analgesia (PCIA), number of total and effective attempts of PCIA pump use, and incidence of postoperative nausea and vomiting were recorded and analyzed statistically. Results Patients in the TEAS group had significantly lower VAS scores at six, 24, and 48 hours after surgery ( P < 0.01); lower BIS scores at 10, 20, and 30 minutes before induction ( P < 0.01); lower levels of postoperative sufentanil consumption; lower number of PCIA attempts and effective rates ( P < 0.01); lower incidences of nausea at 0, six, 24, and 48 hours; and lower incidence of vomiting at 24 hours after surgery ( P < 0.05). The postoperative OAAS scores were similar between the groups. Conclusions TEAS could be a feasible approach for sedation and postoperative analgesia in thoracoscopic pulmonary resection.
