Effect of intraoperative music on quality of recovery after arthroscopic knee surgery: a prospective, double-blind, randomized controlled trial.

BACKGROUND

Various perioperative therapeutic strategies have been used to minimize postoperative complications and enhance recovery. Music intervention has attracted increasing attention as a safe, noninvasive, and cost-effective approach with potential benefits for patient-centered postoperative outcomes. Accordingly, this study investigated the effect of intraoperative music on postoperative recovery quality, as assessed using the Quality of Recovery-40 (QoR-40) questionnaire, as well as its potential analgesic and antiemetic effects in patients undergoing arthroscopic knee surgery.

METHODS

Eighty-two patients were enrolled and allocated to either the music or control group. In the music group, patient-selected tracks were delivered intraoperatively via headphones. Postoperative recovery quality was assessed using the QoR-40 at 24 hours. Pain was evaluated 30 minutes, 2 hours, and 24 hours after arrival in the post-anesthesia care unit. The incidence of postoperative nausea and vomiting (PONV) was recorded at all time points.

RESULTS

Although the total QoR-40 scores did not differ between the groups, the music group demonstrated significantly higher physical comfort scores (p=0.006). The incidence of PONV at 24 hours was lower in the music group (p=0.048), whereas the postoperative pain scores and rescue analgesic requirements showed no significant differences at any assessment point.

CONCLUSION

In patients undergoing arthroscopic surgery, intraoperative music was associated with improvements in physical comfort and PONV, despite no significant difference in the total QoR-40 score.
