Evaluating the effectiveness of listening to classical music during general anesthesia compared to white noise in reducing propofol consumption during vitrectomy surgery 2022-10-07 anticipated 50 Complete https://irct.ir/trial/59935 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Supportive, Randomization description: Patients are divided into two intervention and control groups using six blocks of four in permutation blocks, and this process will be continued until all research participants have been enrolled. When the patient enters the operating room, the anesthesia technician performs this task and plays the audio player file that corresponds to the patient's group. Until the patient exits the operating room, the patient group won't be identifiable to anybody else, Blinding description: Before performing anesthesia, an anesthesiologist will select the patient group using colored cards without the knowledge of the anesthesiologist, surgeon, and patient. After the induction of general anesthesia, headphones will be placed on the patient and the same technician will play the appropriate file for the group. The sound played for the patient will be at a level that cannot be heard by others. The headphones remain in place until the end of the surgery, and when the patient wakes up, the sound is stopped and then the headphones are removed. Until the questionnaire information is completed and the patient is removed from the operating room, no one except the technician will be aware of the patient's group. N/A Vitrectomy Surgery. Intervention 1: Intervention group: After general anesthesia, a headphone is placed on the patient and the classical music file is played through it. The loudness of the sound is checked in advance using a sound sample for the comfort of the patient and is set below 85 dB (to prevent ear damage) based on the recommendation of the World Health Organization. The headphones remain in place until the end of the surgery. When the patient starts to wake up, the sound is stopped and the headphones are removed. Intervention 2: Control group: the white noise file is played for the patient. White noise is a type of sound that is created by combining sounds with different frequencies. If you combine all the imaginable sounds that a human can hear, white noise will be created. The adjective white has been chosen to describe this type of sound for the same reason that it is used to describe white light. Various studies use this sound to compare groups under music therapy as a control group.
