Summary

We plan to evaluate the potential of binaural beat stimulation as a cost-effective tool to improve perioperative patient outcome. Preoperative anxiety and postoperative neurocognitive disorders are two major issues patients have to deal with in the perioperative period. In this context, preoperative stress and anxiety are independent risk factors for postoperative neurocognitive disorders. The primary goal of our proposed study therefore is to reduce preoperative anxiety by stimulating patients with binaural beats. As binaural beats might also entrain brainwaves, the secondary goal of the study is to investigate whether binaural beats can induce alpha oscillatory activity during emergence from anesthesia. This type of oscillation has been demonstrated to be protective for postoperative neurocognitive disorders and might therefore complement the effects of preoperative anxiety reduction.

Conditions

  • Preoperative Anxiety
  • Perioperative Complication

Interventions

OTHER

Binaural Beat Stimulation

During binaural beats stimulation both ears receive a tone which varies slightly in its frequency. If the left ear is stimulated with a sinusoidal wave of 98 Hz and the right ear with a sinusoidal wave of 108 Hz, the brain will perceive this stimulation as a single tone at the mean frequency of 103 Hz. The amplitude of the perceived tone will fluctuate with a frequency that is equal to the difference of the two initial tones, i.e., 10 Hz
