Postoperative nausea and vomiting (PONV) is a common perioperative complication that can increase the incidence of complications such as aspiration, bleeding, incision dehiscence water-electrolyte disorders; prolong hospital stays; and increase medical costs. Transcutaneous electrical acupoint stimulation (TEAS) is important for preventing perioperative PONV, and TEAS may reduce the incidence of PONV by activating the brain-gut axis and regulating autonomic nerve function, anti-inflammatory activity and other mechanisms; however, it is necessary to further promote standardized clinical application through mechanistic research, parameter optimization and high-quality clinical research. This article discusses the risk factors for PONV, the possible mechanism of TEAS in the prevention of PONV and the clinical application of TEAS to provide some reference for the clinical application of TEAS in preventing PONV. • Postoperative nausea and vomiting are related to personal susceptibility, anesthesia and surgery-related factors. • Transcutaneous electrical acupoint stimulation is an important means to prevent perioperative PONV. • Activate the brain-gut axis, regulate autonomic nerve function and anti-inflammatory effects. • Different transcutaneous electrical acupoint stimulation interventions to improve the occurrence of postoperative nausea and vomiting.
