The effect of music during bronchoscopy: A meta-analysis

摘要

Bronchoscopy is considered a stressful procedure performed on patients. Hence, the use of music to ease the anxiety of patients has been examined in various studies, but the results have been inconclusive. The aim of this review is to synthesize the findings of previous studies on the effects of music therapy on the physiological outcomes of patients undergoing bronchoscopy. An electronic database search was performed to identify the literature. Random-effects model was used to combine the results, and meta regression was used to explore the heterogeneity. Seven studies with 829 subjects were included. Results showed that the combined mean differences (95% confidence interval) for systolic and diastolic blood pressure were -11.99 (-15.82, -6.57) and -4.84 (-7.78, -1.90) mm Hg, respectively, whereas that for heart rate was -10.57 (-16.63, -4.51) beats per minute. In conclusion, listening to music reduced blood pressure and heart rate among patients undergoing bronchoscopy. (C) 2016 Elsevier Inc. All rights reserved.
