Globally, preoperative period anxiety is a common occurrence among adults undergoing elective surgery. Not only can preoperative anxiety lead to delays or cancellations of surgical procedures, but it can also negatively impact the prognosis of the condition being treated. To alleviate this issue, non-pharmacological interventions such as prayer, massage, music, imagery, and acupuncture have been widely employed. These methods have proven effective in reducing preoperative anxiety, lowering healthcare costs, and enhancing patient satisfaction. In particular, the traditional Chinese medicine technique of auricular acupressure offers a novel approach to managing preoperative anxiety through its ability to promote circulation, relieve pain, calm the mind, and induce tranquility. However, current research on auricular acupressure primarily focuses on postoperative scenarios, specific diseases, or types of surgery. Through literature review and analysis, this paper summarizes the application of auricular acupressure in alleviating preoperative anxiety among adults undergoing elective surgery and discusses its physiological mechanisms, providing a reference for clinical practice. Although auricular acupressure presents an effective non-pharmacological intervention, further research is needed to validate its efficacy in clinical settings, and attention must be paid to the risk of infection during its application.
