Objective:
To study the effect of music on state anxiety levels in patients undergoing flexible fiberoptic bronchoscopy (FFB).
Design:
Randomized clinical trial using pretests, posttests, and two groups.
Setting:
Pulmonary special-procedures unit of a tertiary-care referral center.
Patients:
Sixty adult patients: 30 patients received music during bronchoscopy and 30 control subjects received no music.
Results:
The study population had baseline state anxiety levels similar to those previously reported in surgical patients (42.6 +/- 13 vs 42.7 +/- 14; p value, not significant [NS]) and higher than those reported in normal working adults (42.6 +/- 13 vs 34.4 +/- 10; p < 0.001). Experimental and control groups were similar in patient and procedure-related characteristics and baseline pre-FFB state and trait anxiety scores. Although trait anxiety scores decreased significantly after the procedure (pooled post-FFB scores of 32.6 +/- 10 vs pre-FFB scores of 35.5 +/- 11; p < 0.001), no reductions were noted in state anxiety (pooled post-FFB scores of 42.8 +/- 13 vs pre-FFB scores of 42.6 +/- 13; p value, NS). More importantly, playing music through headphones during FFB did not result in a statistically or clinically significant reduction in either state or trait anxiety when compared to control subjects.
Conclusion:
Relaxation music administered through headphones to patients during flexible bronchoscopy does not decrease procedure-related state anxiety.
