The purpose of this experimental study was to determine the effects of second and third day postoperative music interventions (music, music video) on pain and sleep in 96 postoperative patients having CABG surgery. The Verbal Rating Scale scores obtained before and after each 30-minute session showed that pain decreased over time for all three groups with no difference across groups. The McGill Pain Questionnaire (MPQ) was administered before session 1 and after session 2, and results indicated that Sensory, Affective, and Present Pain Intensity subscales showed no group difference for pain; however, pain decreased from Day 2 to Day 3 for all three groups. For the evaluative component of pain, those in the music group had significantly (F[2,93] = 4.74, p < .05) lower scores on postoperative Day 2 than the rest period control group. Effects of the intervention on sleep as measured by the Richard Sleep Questionnaire indicated that the video group had significantly (F[2, 92] = 3.18, p < .05) better sleep scores than the control group on the third morning. These findings lend some support for selected music interventions.
