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 cent
er.
Patients: Sixty adult patients: 30 patients received music during bronchosc
opy 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 wo
rking adults (42.6 +/- 13 vs 34.4 +/- 10; p < 0,001). Experimental and cont
rol groups were similar in patient and procedure-related characteristics an
d baseline pre-FFB state and trait anxiety scores. Although trait anxiety s
cores decreased significantly after the procedure (pooled post-FFB scores o
f 32.6 +/- 10 vs pre-FFB scores of 35.5 +/- 11; p < 0.001), no reductions w
ere noted in state anxiety (pooled post-FFB scores of 42.8 +/- 13 vs pre-FF
B scores of 42.6 +/- 13; p value, NS). More importantly, playing music thro
ugh headphones during FFB did not result in a statistically or clinically s
ignificant reduction in either state or trait anxiety when compared to cont
rol subjects.
Conclusion: Relaxation music administered through headphones to patients du
ring flexible bronchoscopy does not decrease procedure-related state anxiet
y.
