The Effects of Perioperative Music Therapy on Women Undergoing Breast Biopsy Surgery
The Effects of Perioperative Music Therapy on Women Undergoing Breast Biopsy Surgery
The purpose of this research is to study the effect music has on women undergoing surgical breast biopsy. Through the facilitation of live and/or recorded music listening, we will examine the perception of patient anxiety, the total amount of propofol required to obtain a BIS reading of 70, and recovery time in the PACU. We will also collect data and evaluate the effect of live and/or recorded music on patient satisfaction. It is hypothesized that:
Music therapy's effect on anxiety in Preoperative.(live vs. recorded):
If the patient is randomly selected to the live music group, the music therapist will prepare a preferred song to be performed live in the preoperative room. If the patient is randomly selected for the recorded music group, she will be given an iPod and headphones and will listen to a recorded version of her preferred song. If the patient is randomly selected for the control group, she will receive standard care and no music. Pre/posttests will be given using a Global Anxiety Visual Analog Scale (GA-VAS).
Music therapy's effect on propofol requirements intraoperatively:
Subjects in the live music group and subjects in the recorded music group will listen to recorded music intraoperatively. All subjects will receive equal amounts of fentanyl and versed. Subjects will receive fentanyl in the amount of 1 microgram per kilogram and versed (midazolam) in the amount of 0.02 milligrams per kilogram from the nurse anesthetist. An ipod with headphones will be given to the subject when she is being prepared to move to the operating room. The board certified music therapist will initiate recorded music (harp selections). Recorded music will be relaxing harp selections. The board certified music therapist will accompany the subject to the operating room and assure volume levels and electronic equipment function properly.
Anesthesia personnel will apply BIS monitor before propofol administration. Anesthesia personnel will titrate propofol to obtain BIS reading of 70 or lower and record the propofol in micrograms per kilogram per minute, infusing at that point. Signal Quality Index (SQI) will be recorded when the BIS reaches 70 to give credibility to the BIS monitor. SQI is a measure of the signal quality for the EEG channel source and is calculated based on impedance data, artifact, and other variables. The total amount of propofol for the case will be recorded as total milligrams received. Anesthesia personnel will record Observer's Assessment of the Alertness/Sedation (OAA/S) when BIS monitor reaches 70 or below as incidental data point. A score of 3 on OAA/S indicates that the patient responds only after mild prodding and shaking. OAA/S will be compared to BIS reading.
Time in PACU and Patient Satisfaction:
Recorded music will continue playing until the subject has met discharge criteria according to University Hospital's policy and procedure. The amount of time between when the patient leaves the operating room and meets discharge criteria (determined by nurse) will be recorded. Patient satisfaction will be recorded using a Likert scale: 7= highly satisfied; 1=not at all satisfied after the subject has met her discharge criteria.
Controls: The control group subjects will receive standard anesthesia, nursing and surgical care. All rating procedures will be the same. Controls will wear noise reducing headphones. The music therapist will not accompany control patients following surgery. When the trial is complete, the music therapist will offer the control subject a CD of the recorded music once she has met discharge criteria and all data is recorded. This will occur for the sake of ethics.
