Background: Postoperative anxiety and pain were the relatively common clinical problem. In the last few years, transcutaneous electrical acupoint stimulation (TEAS) was increasingly used to improve postoperative anxiety and pain. However, there was a lack of integrated analysis and evaluation of existing evidence. Hence, the me-ta-analysis intended to assess the efficacy of TEAS for relieving postoperative anxi-ety and pain. Methods: We checked Embase, Cochrane Library, PubMed, China Wanfang, and China National Knowledge Infrastructure (CNKI) for randomized controlled trials (RCTs) on the efficacy of TEAS on postoperative anxiety and pain published from January 2013 to January 2023. Postoperative anxiety was assessed by the State Anxi-ety Inventory (STAI) or Hospital Anxiety and Depression Scale (HADS). The Visual Analogue Scale (VAS) was utilized for evaluating postoperative pain at 24 hours. All data were analyzed by the RevMan 5.4 version. Results: The meta-analysis ultimately included ten articles with a total of 2,705 pa-tients. Our analysis suggested that TEAS significantly improved the postoperative anxiety (RR=0.61, 95%Cl=0.40~0.93,i²=0, P<0.05) and the VAS score at 24 hours (MD=-1.02, 95%Cl=-1.48~-0.57, i²=81%, P<0.05). In addition, TEAS decreased the incidence of postoperative nausea and vomiting (PONV) (RR=0.62, 95%Cl=0.51~0.75, i²=43%, P<0.05) and dizziness (RR=0.55, 95%CI=0.31~0.97, i²=41%, P<0.05). Conclusion: The current study demonstrated that TEAS reduced the incidence of postoperative anxiety and the VAS score at 24 hours, and improved PONV and diz-ziness. However, additional high-quality articles were needed to support this view at a later time.
