Binaural Sound Effects for General Anesthesia (BS)
30 minutes before entering the operating room, the anxiety score is evaluated using a visual analogue scale (VAS) score, and stereo headphones, which can transmit binaural beat, are put on. According to a computer-generated assignment table, subjects are divided into an experimental group and a control group. Binaural beat is applied to the experimental group for 20 minutes, and a silent state is applied to the control group for 20 minutes. After entering the operating room, electrocardiogram, pulse oxymetry, non-invasive blood pressure monitor, and sensor for depth of anesthsia are attached. Before induction of anesthesia, the anxiety score is evaluated on a VAS, again. For anesthesia induction, propofol is administered at a rate of 10 mg every 15 seconds over 5 seconds. Assess the amount of propofol administered until the response to voice ("Open your eyes.") is absent, the subject's eyelash reflex disappears, and the PSI reaches below 50. Discontinue propofol injection when all three assessments (unresponsiveness to voice, loss of eyelash reflexes, Patient Sate Index (PSI) ≤ 50) become positive.
