Not Applicable

Completed

• Conditions: Arthroplasty, Replacement, Knee
• Interventions: Other: Music Therapy

• Registration Number: NCT03569397
• Lead Sponsor: University of Alabama at Birmingham

Brief Summary

For millennia, people have listened to and enjoyed music for entertainment, as a distraction from daily troubles, and as a means to relax and relieve stress. It is no real surprise that the relaxing and stress-relieving effects of music have been shown in patients having surgery. For patients having surgery with spinal anesthesia, music therapy during the operation decreases sedation requirements, anxiety and may improve patient satisfaction. Music therapy during surgery may also lead to a decreased stress response, as evidenced by more stable cortisol levels. Studies done previously have included patients undergoing various surgical procedures, however no studies have been done specifically for patients undergoing total knee arthroplasty. Because total knee arthroplasty is a common procedure usually done under spinal anesthesia at our institution, we would like to study the effects music therapy could have on our patient population.

Detailed Description

A. Patients who consent to the study will be randomized 1:1 to either the investigational group ("Music Therapy" group) or the control group ("No Music" group). Participants will be randomized using a random number generator.

B. Consent and study enrollment will occur in the preoperative area prior to surgery. After enrollment, all patients will complete a State-Trait Anxiety Assessment. Patients in the "Music Therapy" group will be asked to choose a genre of calming music that they would like to listen to during the operation (instrumental, jazz, classical). All patients enrolled in the study will continue to receive routine preoperative care but will also have a baseline cortisol level drawn. This blood draw will be compared to a cortisol level at the end of surgery to assess the patient's physiologic stress response to surgery.

a. After proceeding to the operating room, all patients will receive routine preoperative care during placement of spinal anesthesia. In addition to monitors routinely placed prior to spinal block, a Bi-Spectral Index monitor will be placed on the patient's forehead to monitor sedation levels during the procedure. A Bi-Spectral Index monitor is a noninvasive series of patches placed on the patient's forehead that, through a propriety equation creates a number (1-100) from processed electroencephalography waves that correlates with depth of sedation or anesthesia. After the spinal anesthetic block is placed, the patients in the "Music Therapy" group will wear headphones that will play their pre-selected music. The "No Music" group will receive intraoperative standard of care with no headphones. Headphones will be worn by the "Music Therapy" patients until the procedure is finished (skin incision is closed).

C. During the procedure, routine intraoperative sedation consisting of propofol, fentanyl and midazolam will be administered. All patients will be given 1 mg midazolam, 50 mcg fentanyl and propofol dosing titrated to maintain a Bi-Spectral Index level \<70, which correlates to moderate sedation.9

D. At the end of the surgical procedure (within 30 minutes of incision closure), a serum cortisol level will be drawn to assess the physiologic stress response to surgery.

E. All patients will receive standard postoperative care in the post-anesthesia care.

F. On postoperative day 1, all patients will again complete a State-Trait Anxiety Assessment. Additionally, patients in the music therapy group will complete a satisfaction survey.

Primary Outcome Measures

Name	Time	Method
Patient Satisfaction	Postoperative day 1	On a scale of 1-5 (Likert scale) patients were asked to rank their satisfaction with their perioperative care. 1 indicates poor satisfaction, 5 indicates excellent satisfaction. Only patients in the music therapy group were asked for their satisfaction ranking.
