The Effect of Music on the Sleep Quality and Vital Signs of the Chronic Renal Failure Patients Who are Getting Hemodialysis Treatment

Abstract

Objective: The aim of this study is to determine the effect of music, which they were made listen to, on the sleep quality and vital signs of the patients with chronic renal failure who are getting hemodialysis treatment. Material and Methods: This study was planned as a randomized controlled and experimental clinical study which conducted between the dates of March 15-November 30, 2010 in the nephrology service. In total, 70 patients, who were suitable for the sample selection criteria and who gave consent to participate in the study, were included in the research sample; 35 of them being experimental group patients, and 35 of them being control group patients. The sample size was calculated with power analysis. Individual introduction questionnaire, Pittsburgh Sleep Quality Index (PSQI) which measures the sleep quality, and patient monitoring form for monitoring the findings, were used in the collection of data. Experimental group patients were listened to Turkish Art Music for 30 minutes for 4 days in the evening before they go to sleep. Systolic and diastolic blood pressures, pulse rates and breathing rates were measured and recorded for 4 days before (0. min) and just after the music (30. min). Sleep quality was evaluated by using PSQI. In patients in the control group, systolic and diastolic blood pressures, pulse rates and breathing rates were measured and recorded for 4 days in the 0. and 30. minutes for this group by considering the hour in the experimental group after (30.min) and before (0. min) the patients were listened to music in that group. PSQI was reapplied after 4 days from the first interview, and the quality of sleep was reevaluated. Results: In the patients in the experimental group, systolic and diastolic blood pressure, pulse and breathing rates show a decrease in the 30. minute just after they were being listened to music for 4 days. The mean PSQI score of the patients in the experimental group at the end of the 4th day (5.97±1.20) was found to be lower than their mean PSQI score at the 1st day (9.80±1.57). The mean PSQI score of the patients in the control group at the end of the the 4th day (10.97±1.76) was found to be higher than their mean PSQI score at the 1st day (9.86±1.87). Conclusion: Music theraphy may be used as an efficient intervention which decreases vital signs and increases the sleep quality in the patients who are getting hemodialysis treatment.
