Perioperative Effect of Music in Patients Undergoing General Anesthesia

Anxiety is a transient emotional state characterized by feelings of tension, apprehension, nervousness, fear, and heightened activation of the autonomic nervous system in response to a specific current or potential event or situation. Music therapy is a cost-effective and safe intervention applied to health care, that has been incorporated into different branches of medicine, including anesthesiology, showing economic benefits and as an adjunct to pharmacological therapy, allowing the use of lower doses of perioperative drugs, thus reducing their deleterious effects. The main objective of this randomized clinical trial is to evaluate whether the application of music during the perioperative period reduces perioperative anxiety in patients undergoing general and digestive surgery under general anesthesia.Patients between 18 and 60 years of age, classified according to the American Society of Anesthesiologists (ASA) I-IV, scheduled for general surgery and who have signed the informed consent, will be randomized to receive music therapy in the immediate perioperative period or not. Perioperative anxiety, stay in the PACU, incidence of postoperative pain and intraoperative opioid consumption will be compared between both groups.
