A study of the impact of preferred music on the pain intensity and physiological parameters of patients after coronary artery bypass surgery Download PDF

Introduction and objective: Cardiac surgery, which is often associated with pain and dysfunctions in multiple systems, creates high levels of stress in patients. Since pain and thereby stress can have impact on physiologic parameters and treatment output of these patients, the present study aimed to study the impact of preferred music on the pain intensity and physiological parameters of patients after coronary artery bypass surgery. Materials and method: the present study was a clinical trial study and it was conducted on 86 patients undergoing open heart surgery. In order to sample, researcher referred to Cardiac Surgery ward of selected hospitals and selected the samples and demographic information questionnaire were filled out by participants. After surgery and entering the patient in the ward, at first, pain intensity and physiologic parameters were measured in both group. Then, in experimental group, in addition to the usual nursing care, the music preferred by the patient was play for him/her for 20 min using headphones and Mp3 player. In control group, pain intensity and physiologic parameters were recorded within 20 min after using the headphones without playing the music. After the end of intervention, pain intensity and physiologic parameters of the both groups were measured again. The obtained data was analyzed by pair and independent t-test. Results: comparing pain intensity and physiologic parameters (systolic and diastolic blood pressure, heart rate, respiration, temperature and blood oxygen saturation level) before and after intervention indicated that in the experimental group, there was a significance difference between pain intensity before and after the intervention (p-value0.001). The results indicated that after intervention, there were significant differences between the two groups just in diastolic blood pressure (p-value=0.024) and blood oxygen saturation level (p-value=0.14) and no significant difference was observed between them in other physiologic parameters. Also, after intervention, significant decrease in heart rate (p-value=0.036) and significant increase in blood oxygen saturation level (p-value=0.039) were observed. Discussion and conclusion: using the preferred music in patients after coronary artery bypass surgery significantly reduced the pain and diastolic blood pressure and increased the blood oxygen saturation level in the experimental group and no difference was observed in other physiologic parameters after intervention.
