Therapeutic Effects of Music on Procedural Outcomes

This study will evaluate whether listening to low-tempo instrumental music during gastroscopy and/or colonoscopy can reduce the amount of sedative medication needed during the procedure. Adults undergoing elective gastroscopy and/or colonoscopy with sedation will be randomly assigned to one of two groups. One group will listen to low-tempo instrumental music (60-80 beats per minute) through headphones during the procedure in addition to receiving standard sedation. The other group will receive standard sedation without music. The main outcome of the study is the amount of sedative medication required during the procedure. The study will also compare pain after the procedure, time until discharge, patient satisfaction, and changes in heart rate and blood pressure between the two groups. The researchers hypothesize that patients who listen to low-tempo music will require less sedative medication and may have improved recovery and patient-reported outcomes compared with patients receiving standard sedation alone.
