The effect of audio-visual distraction by music on hemodynamic parameters in patient undergoing bronchoscopy

Bronchoscopy is a stressful procedure. Increased anxiety raises oxygen demand during bronchoscopy and affects cardiac output and blood pressure. The purpose of this study was to evaluate the effect of distraction by audiovisual folk music on hemodynamic parameters in patients undergoing bronchoscopy.
This randomized clinical trial was performed in Imam Ali Hospital in Zahedan. We used convenience sampling method for three-month from July to September 2015 and sixty patients who had been scheduled for bronchoscopy were randomly divided into control (n= 30) and experimental (n = 30) groups. Demographic information forms and hemodynamic parameters record chart were used for data collection .During bronchoscopy, every patient listened to an audiovisual folk music which had been selected by himself. The control group received routine care. Using SPSS software version 21, data were analyzed by chi-square (X2), independent t-test, paired t-test and repeated measures analysis of variance.
The results showed that two groups had statistically significant difference in relation to hemodynamic parameters during and after intervention (p=0.0001). The pattern of decline was not similar in both groups. Distraction by audiovisual folk music led to decreased heart rate and blood pressure, and also increased oxygen saturation in the experimental group.
Audiovisual folk music selected by every patient, during bronchoscopy resulted in the improvement of the hemodynamic parameters. Therefore, use of this method is recommended during invasive diagnostic and treatment procedure especially bronchoscopy.
