Backgrounds: Studies have been planned to evaluate the pre-operative physiological parameters among the patients undergoing day surgery. The effects of music could attenuate the patients from being over anxious have only been discussed in some literatures. This study was designed to determine whether music could improve the pre-operative anxiety levels in outpatients undergoing daycare surgery. The expected results of this study could provide some basic information for improvement of pre-operative nursing care quality.
Objectives: The purpose of this study was to understand effects of sedative
music on reducing state-anxiety of patients before day surgery.
Methods: A total of 172 patients from a day surgery center located in northern part of Taiwan were enrolled in this study and randomly assigned into either a study group with pre-operation music sedation (n = 86) or a second group undergoing day surgery without music sedation (n = 86). Patients’ physiological parameters and " State-Trait Anxiety Inventory” from both groups were assessed before and after treatment by a blinded investigator in both groups. Patient’s basic physiological parameters and "Revised State-Trait Anxiety Inventory" were used to measure subjects' level of anxiety. Quantitative data were analyzed by multiple regression technique. Data from questionnaires were analyzed inductively.
Results: After music sedation, the patient’s basic physiological parameters (heart rates, systolic/diastolic pressures) were significantly reduced in the study group. Furthermore, the pre-operative anxiety was significantly reduced after the procedure in contrast to the group that did not receive music sedation. The reduction of pre-operative anxiety levels were more prominent in the highly anxious patients group.
Conclusions: Music sedation results in significant alleviation of pre-operative anxiety in the highly anxious patients group receiving daycare surgery. The results of this interventional investigation could be further explained by the patient’s brain cortical response to the release of body cortisol caused by the pre-operative music sedation.
