RESUMEN
PURPOSE: This study investigated the effects of binaural beat music on anxiety, pain, and vital signs in Korean surgical patients. DESIGN: This study used a non-equivalent control group pre-and post-test design. METHODS: This study included 54 patients who underwent spinal nerve plastic surgery under local anesthesia. The experimental group listened to binaural beat music twice, using headphones (20 minutes before surgery and 30 minutes after surgery). We measured the participants' pain and anxiety levels using a visual analog scale for pain and anxiety. In addition, we checked the participants' systolic and diastolic blood pressure and heart rate using a blood pressure monitor. FINDINGS: The experimental group displayed significantly lower anxiety and pain scores than the control group after the intervention. Meanwhile, systolic and diastolic blood pressure did not show any statistically significant differences between the groups. However, the experimental group had a significantly lower pulse rate than the control group. CONCLUSION: Our research findings showed that using binaural beat music in the nursing care of surgical patients under local anesthesia can effectively reduce postoperative pain and anxiety, contributing to improved mental health and physical well-being after surgery.
