The Effect of Music on Preventing Intraoperative Awareness in Pediatric Patients Undergoing Open-Heart Surgery

Abstract

AbstractUse of music has the potential to positively affect patient perception during of surgical treatment. Intraoperative awareness is the most frustrating complication in patient undergoing surgery under general anesthesia. Study Design was Quasi-experimental research design. Three tools were used to conduct this study namily: Preoperative assessment tool, intraoperative assessment tool and postoperative assessment tool. Method: In a prospective, randomized double blind study, patients were randomized into two equal groups; In C group (n = 25) patients acted as the control and did not listening to music, while in music group (n = 25) patients listening to music. In both groups, auditory evoked potentials index electrodes connected before induction of anesthesia at operative room to detect depth of anesthesia and occurrence of awareness. An interview with the patients and their parents to evaluate occurrence of awareness by using a semi-structured in-depth questionnaire. The main results: The results of the current study revealed that there was statistically significant decrease in occurrence of awareness in music group versus the control group (P value =0.000***). Conclusion: The application of music was highly effective in reducing awareness.
