The effect of preferred music on physiological parameters of pain in

Abstract

Background & Aim: Pain is a major unpleasant experience for patients in Intensive care unit. The aim ofthis study was to investigate the effect of listening to preferred music on physiological parameters ofunconscious patients as assessment indicator of pain.Methods & Materials: In this clinical trial study, 72 unconscious patients were selected form intensive careunits of Sina and Imam Khomeini hospitals in Tehran by convenience sampling method. Patients wererandomly allocated into two groups (intervention and control groups). In intervention group, patients listenedto music selected by their family members for 30 minutes a day for three consecutive days. intervention(music) patients for 30 minutes without any intervention and rest in the bed. Patients in control group did notlisten to music. Physiological parameters including systolic blood pressure, diastolic blood pressure, meanarterial pressure, heart rate and peripheral capillary oxygen saturation (spo2) were obtained 10 minutes beforeand 30 minutes after intervention. Data were analyzed using SPSS V.18 software.Results: There was no significant difference between two groups in terms of physiological parameters beforeintervention. There was a statistically significant decrease in systolic blood pressure (P=0.006) and meanblood pressure (P= 0.038) of patients in intervention group. There was a significant increase of heart rateamong patients in intervention group . There was no difference between the two groups in terms of diastolicblood pressure.Conclusion: Results of this research provide evidence to serviceable the use of music in this patientKeywords: Pain, Music, vital signs, physiological parameters, unconscious
