effect of music on postoperative physiological parameters in patients under open heart surgery

Music as a therapeutic non-invasive tool-could be used as an effective intervention in nursing practice. the aim of this study was to survey effect of music upon patients’ physiological parameters following open heart surgery. a quasi-experimental study was performed on 60 patients under open heart surgery referred to intensive care unit. patients were randomly divided into two groups including experimental and control groups. patients in experimental group listened to non verbal music for 30 minutes after surgery by headphones. the control group did not receive any intervention. before and after intervention, physiological parameters was measured in two groups. a significant difference was demonstrated in pulse rate, systolic blood pressure and oxygen saturation of experimental group’s patients. but there was no significant difference in respiratory rate and diastolic blood pressure. as for music would reduce some of the physiological parameters, and have some advantages, it could be suggested to use for controlling physiological parameters following surgery.
