Transcutaneous electrical acupoint stimulation may reduce perioperative hypothermia in adults undergoing elective VATS.

This randomized controlled trial investigated the effect of transcutaneous electrical acupoint stimulation (TEAS) on perioperative hypothermia. The study population consisted of adults scheduled for elective video-assisted thoracoscopic surgery (VATS) under general anesthesia. The sample size was not reported. The setting was not reported. Funding or conflicts of interest were not reported.

The intervention involved TEAS applied at predefined acupoints starting 30 min before anesthesia induction and continuing until the end of surgery. The comparator was sham stimulation. The primary outcome was the incidence of perioperative hypothermia, defined as a core temperature. The follow-up period extended until the end of surgery. Specific results for the primary outcome were not reported in the provided data.

Safety and tolerability data were not reported. Discontinuations were not reported. Serious adverse events were not reported. Adverse events were not reported. The study limitations include that evidence from randomized controlled trials remains limited. Practice relevance was not reported. The certainty note was not reported.
