* The perioperative period can be a significant source of psychological burden, anxiety and fear for patients * Both pharmacological and non-pharmacological methods have been proposed in order to alleviate perioperative stress * Music is one of the non-pharmacological methods which have been used in this context, with favorable effects both preoperatively and postoperatively * The attenuation of perioperative stress through music listening is probably due to the activation of emotional and cognitive processes that evoke feeling of pleasure and can distract patients' attention from fear and unpleasant thoughts related to the surgical procedure * Little information is available regarding the effect of intraoperative music listening on anesthetized, unconscious patients * There is a notion that general anesthesia does not completely abolish auditory perception and that some processing of intraoperative events can occur in unconscious patients, even in the absence of postoperative recall * The investigators hypothesis is that intraoperative music listening can decrease anesthetic requirements and reduce sevoflurane consumption in female patients subjected to abdominal hysterectomy for benign disease.
