When the literature is examined, there is almost no application of EFT on surgical patients. In a quasi-experimental study conducted by Kalroozi et al. (2022) with 70 women who underwent breast cancer surgery and received complementary treatment, the effect of EFT on sleep quality and happiness level was investigated. Six sessions of EFT were applied to the control group. A statistically significant difference was found between the intervention and control groups in sleep quality and happiness scores before and after the intervention. In a randomised controlled study conducted by Menevşe et al. (2024) examining the effect of EFT applied to patients before laparoscopic cholecystectomy on surgical fear and anxiety, 56 patients were included in the control and 56 patients in the intervention group. While routine care and treatment practices were applied to the control group, EFT was applied to the intervention group. EFT application was continued for three rounds and approximately 25-30 minutes. As a result of the study, it was found that EFT was useful in clinical practice in the preoperative period and reduced surgical anxiety and surgical fear. In a quasi-experimental study involving 108 people in which the effects of EFT and music on anxiety and vital signs were examined before lumbar disc herniation surgery, it was found that both music and EFT reduced anxiety and regulated vital signs before surgery, and EFT was more effective than music in regulating anxiety and respiratory rate. In previous studies, pain, pain belief and anxiety in surgical patients have not been examined together. It is thought that the study will have a positive effect on the patient outcomes (anxiety, pain, pain belief) of patients undergoing CABG, thus increasing the holistic approach in the care of patients and having a positive effect on the quality of life of individuals.
