Effects of Binaural Beats on Inhaled Anesthetic Requirements During General Anesthesia in Pediatric Patients

Effects of Binaural Beats on Inhaled Anesthetic Requirements During General Anesthesia in Pediatric Patients: A Prospective, Randomized Controlled Trial

• Status: Not Yet Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 68 (estimated)
• Sponsor: Seoul National University Hospital · Academic / Other
• Sex: All
• Age: 3 Years
• Healthy volunteers: Not accepted

Summary

The hypothesis of this study is that continuously delivering binaural beats with a phase difference corresponding to the slow-delta frequency band during anesthesia in pediatric patients can clinically and significantly reduce the required dose of the commonly used inhalational anesthetic, sevoflurane. To test this hypothesis, the study will compare the average end-tidal concentration of sevoflurane between a group exposed to continuous binaural beats (approximately 1 Hz phase difference) during surgery and a control group not exposed to such auditory stimulation.

Conditions

• General Anesthesia
• Children

Interventions

Type	Name	Description
OTHER	Application of Binarual Beat	The binaural beat audio file consists of pure tones at 431 Hz in the left ear and 432 Hz in the right ear, delivered via earphones continuously until the end of anesthesia.
