Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to learn about the effects of binaural beats on maintenance of general anesthesia in patients undergoing thyroidectomy without intraoperative neuromonitoring.

The main question it aims to answer is:

* 1\) Does applying binaural beats during surgery reduce the gas anesthetics (especially sevoflurane) requirement to maintaining adequate anesthetic depth during general anesthesia?
* 2\) Does applying binaural beats during surgery affect intraoperative hemodynamic stability or post operative nausea and vomiting?

Participants will wear headsets with a sound generator which contains music files (binaural beat file in the intervention group (BB) ; silent file in control group (C)) according to the randomization. Researchers will compare the BB and C group to see if intraoperative binaural beats reduce the requirements of sevoflurane for maintaining adequate anesthetic depth.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will look at thyroidectomy patients without neuromonitoring. Before entering the operating room, patients will be randomized according to the randomization table, with the test group receiving a sound generating device with a binaural sound file and the control group receiving a sound generating device with a silent file. After entering the operating room, electrocardiogram, pulse oxymetry, non-invasive blood pressure monitor, and sensor for depth of anesthesia will be attached. At the beginning of anesthesia induction, the headset will be placed on the patient and a sound generator will be connected to the headset to play the file. The induction of anesthesia will be done with administration of fentanyl and propofol in both groups, and after confirming that the patient is unresponsive to voice, rocuronium and sevoflurane will be administrated to the patient. During the operation, the inhaled anesthetic concentration will be adjusted to maintain a patient state index (PSI) between 25 and 50. Fentanyl can be titrated up to 100 mcg to account for the hemodynamic response to intraoperative pain, and neuromuscular blocking agents are titrated to maintain a train of four (TOF) count of 1-3. The headset is continuously applied to the patient during surgery, and blood pressure, pulse oximetry, PSI, end tidal sevoflurane and end tidal minimal alveolar concentration will be monitored during the operation. At the time of the final suture of the skin, the sound generator will be removed from the headset. Save the raw EEG data from the Sedline® sensor for further analytical evaluation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control

In the control group, a silent state (a wave file made without sound) is applied via the sound generator and a headset, at the starting of general anesthesia induction. The sound generator volume is set to 60 dB. The sound generator and the headset is assigned after the randomization, and is blinded to the patient and the investigator. This sound is applied during the operation, and at the time of the final skin suture, the sound generator and the headset will be removed from the patient.

Group Type PLACEBO_COMPARATOR

Silent

Intervention Type PROCEDURE

Apply wave file created in silence.

Binaural Beat

In the experimental group, the binaural beat which is produced by the beat of 1Hz difference is applied via the sound generator and a headset, at the starting of general anesthesia induction. The sound generator volume is set to 60 dB. The sound generator and the headset is assigned after the randomization, and is blinded to the patient and the investigator. This sound is applied during the operation, and at the time of the final skin suture, the sound generator and the headset will be removed from the patient.

Group Type EXPERIMENTAL

Binaural beats

Intervention Type PROCEDURE

Apply wave file which is intended to generate binaural beats by applying waves of different frequency (1Hz difference) in each ear.
