Using binaural sound effects to reduce anxiety during general anesthesia
The Effect of Preoperative Binaural Sound on Propofol Dose Required for Induction of General Anesthesia: a Randomized, Placebo-controlled Trial
NA · Seoul National University Hospital · NCT05431881
This study tests if listening to special sounds called binaural beats can help adults feel less anxious before getting general anesthesia.

What this trial studies
This clinical trial evaluates the effectiveness of binaural beats in reducing anxiety in adult patients undergoing general anesthesia. Participants are randomly assigned to either an experimental group that listens to binaural beats or a control group that experiences silence for 20 minutes before anesthesia induction. Anxiety levels are measured using a visual analogue scale before and after the intervention. The amount of propofol required for anesthesia induction is then assessed to determine if binaural beats have a significant impact on reducing anxiety and the dosage needed.
Who should consider this trial
Good fit: Ideal candidates are adults aged 20-50 who require general anesthesia and meet specific health criteria.
Not a fit: Patients with hearing impairments, cardiovascular issues, or those on certain medications may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could lead to reduced anxiety and lower dosages of anesthetics required for patients during surgery.
How similar studies have performed: While the use of binaural beats is a novel approach in this context, similar studies have shown promising results in reducing anxiety in other settings.
