![]() After that, propofol is not administered. Propofol is administered until all three evaluations (no response to voice, loss of eyelash reflexes, PSI ≤ 50) are positive. Assess the amount and time of propofol administered until the response to the voice ("Open your eyes.") is absent, the patient's eyelash reflex disappears, and the PSI reaches below 50. For anesthesia induction, 10mg propofol is administered every 15 seconds for 5 seconds. Preoxygenation with oxygen 8L/min is sufficient, and in order to reduce venous pain caused by propofol injection, 1% lidocaine 50mg is pre-administrated. After changing the volume to 0, take off the headphones, and evaluate the anxiety score using VAS. Prepare by connecting a 3-way at the most proximal part of the intravenous cannula. The volume is set to a level corresponding to 60dB.Īfter entering the operating room, start monitoring vital signs and depth of anesthesia (PSI) by attaching an electrocardiogram, pulse oxymetry, non-invasive blood pressure monitor, and sedline. The sound generator is a smartphone device, which is hung on the transport bed. A third party unrelated to the experiment sees the randomization table and applies binaural sound to the experimental group and silent state (silent sound file) to the control group for more than 20 minutes. Procedure: Binaural beat Procedure: Silentģ0 minutes before entering the operating room, anxiety is evaluated on a VAS scoer (0-100mm, a ruler without scale) and stereo headphones, which can transmit binaural beat, are put on. Discontinue propofol injection when all three assessments (unresponsiveness to voice, loss of eyelash reflexes, Patient Sate Index (PSI) ≤ 50) become positive. 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. Before induction of anesthesia, the anxiety score is evaluated on a VAS, again.įor anesthesia induction, propofol is administered at a rate of 10 mg every 15 seconds over 5 seconds. After entering the operating room, electrocardiogram, pulse oxymetry, non-invasive blood pressure monitor, and sensor for depth of anesthsia are attached. According to a computer-generated assignment table, subjects are divided into an experimental group and a control group.īinaural beat is applied to the experimental group for 20 minutes, and a silent state is applied to the control group for 20 minutes. ![]() Why Should I Register and Submit Results?ģ0 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.In addition to the full 3D Surround experience, the stereo version is included in your purchase of 3DS, with the same sound material and production-ready for more common formats. It also sounds incredible on its own, perfect for any nature show clips or segues. This library makes for the perfect outdoor soundscape to duck dialogue, music, or other sound effects. ![]() Whether your project covers camping or hunting scenes, outdoor survival games, or strolls in the park, get the mood right with this collection of rainy days and birdsong.
