Effect of Binaural Beats on Anxiety and Tolerance in Patients Undergoing Upper Gastrointestinal Endoscopy Without Sedation: A Randomized Controlled Trial.

Abstract

Objective: Binaural beats, or the perceptual auditory illusions created when simultaneously presenting two similar frequencies to each ear separately, have been used to reduce anxiety in various procedures. Unfortunately, no prior study involved preprocedure binaural music exposure among patients undergoing upper gastrointestinal endoscopy, and this study sought to investigate its effect on anxiety and tolerance among participants undergoing sedation-free upper gastrointestinal endoscopy. Methods: The prospective, controlled, randomized trial included the participation of 96 Turkish patients aged between 18 and 70 years who were scheduled for an upper gastrointestinal endoscopy, regardless of sex or illness, and were divided randomly into two different groups to undergo endoscopy, namely, the binaural beats group (n = 48) and a control group (n = 48). Patients in the binaural beat music group wore headphones, and music was given 15 mins before endoscopy; however, no particular treatment was given for either group. Anxiety levels were assessed by using the State Trait Anxiety Inventory questionnaire, in addition to changes before and after endoscopy to measure patient satisfaction based on the physician's recorded numbers of retches noted by doctors as tolerance was documented and compared among both groups. Results: The results showed that following this procedure, in the music group, state scores remained significantly lower than before them (p = 0.016), compared with the control group (p > 0.05). There was no significant difference regarding changes in diastolic or systolic heart rate or blood pressure (p > 0.05). However, the procedure tolerance and satisfaction scores were significantly higher in the music group than those without music (p < 0.05). Conclusion: For patients undergoing upper gastrointestinal endoscopy, music with binaural beats was found to significantly reduce anxiety levels and increase patient tolerance, providing an alternative option to sedative medications as a potential sedative treatment option.Clinical trials registration number: NCT06114524.
