Although mechanically ventilated patients experience numerous stressors, they have not been included in music therapy stress reduction and relaxation studies. To examine selected psychophysiologic responses of mechanically ventilated patients to music. A two-group experimental design with pretest, posttest, and repeated measures was used. Twenty mechanically ventilated patients were randomized to a music-listening group or a nonmusic (headphones only) group. Physiologic dependent measures--heart rate and rhythm, respiratory rate, systolic and diastolic blood pressure, oxygen saturation, and airway pressure--were collected at timed intervals. Psychologic data were collected before and after intervention using the Profile of Mood States. Using repeated measures analysis of variance, results for heart rate and respiratory rate over time and over time between groups were significant. Between-group differences were significant for respiratory rate. Significant differences were found via t test for the music group's Profile of Mood States scores. No adverse cardiovascular responses were noted for either group. Data indicated that music listening decreased heart rate, respiratory rate, and Profile of Mood States scores, indicating relaxation and mood improvement.
    • "Despite the perceived benefits of music, there are very few studies validating its use in critically ill patients. Those studies that have examined the effect of music have only done so in the course of a single listening session, either by observing a beneficial effect in heart rate and respiratory rate [5] or in overall anxiety [6]. The long-term effects remain more uncertain, as one study noted that the decrease in blood pressure observed during a music listening session was accompanied by a corresponding rise after cessation of treatment [7].

    • "A randomized control trial with 28 adults found that 13 weeks of music therapy resulted in a decrease in mood disturbance as measured by the P.O.M.S. (McKinney et al., 1997). Enhanced mood, as measured by the P.O.M.S., was found among 20 mechanically ventilated patients when exposed to music listening (Chlan, 1995). Although this chapter focuses on the act of singing versus listening to music, the research has found that both singing and listening result in enhanced mood as measured by P.O.M.S., yet the results for those individuals within singing groups yielded a higher effect (Unwin et al., 2002).

    • "Contrary to our expectations, these parameters fluctuated and no definitive decrease was seen. Our results are in contradiction with previous studies where listening to music led to: a decrease in heart and respiratory rate (Chlan 1995Chlan , 1998), a decrease in mean blood pressure and respiratory rate (Wong et al. 2001), a decrease in systolic and diastolic blood pressure (Almerud & Petersson 2003) and decreases in respiratory rate, heart rate and systolic and diastolic blood pressure (Lee et al. 2005). These differences may be due to our small sample size. "
    [Show abstract] [Hide abstract] ABSTRACT: A pilot study designed as future randomised controlled trial was carried out to determine the effects of music on physiological responses and sedation scores in sedated, mechanically ventilated patients. Mechanically ventilated ICU patients, even when receiving intravenous sedatives, may experience stress and anxiety. One possible intervention to reduce stress and anxiety is listening to music. A randomised controlled trial design with repeated measures was used. Data were collected over a six-month period in 2006. Twenty subjects were randomly assigned to either the experimental or control group. Subjects in the experimental group listened to music three times for 30 minutes over two days; subjects in the control group undertook three 30 minute rest periods. Physiological effects of music on systolic, diastolic and mean arterial blood pressure and heart and respiratory rate were assessed. Sedation scores were also measured. Physiological parameters did not show a significant difference between the groups. Patients in the experimental group showed significantly higher Ramsay (sedation) scores than patients in the control group after the first session. The higher scores indicate that patients were less responsive to external stimuli. Our results suggest that listening to music leads to higher sedation scores in sedated, mechanically ventilated ICU patients. No significant decreases in physiological parameters were observed. Listening to music showed no negative changes in the condition of these patients. Future research should focus on the use of other measures, such as stress hormones, to assess stress in sedated, mechanically ventilated ICU patients. For the sedated, mechanically ventilated ICU patient, the benefit of music may lie in the associated (deeper) level of sedation that is achieved, which in turn may make the patient less susceptible to stress and anxiety.
