Brief Summary

Background: Delirium is a common acute confusion state in patients in intensive care units (ICUs). It has been linked to poor clinical prognoses (e.g., prolonged ICU stay) in critical patients. Furthermore, it might connect with long-term cognitive dysfunction. Mostly, pharmacological treatments have been frequently prescribed for preventing ICU delirium; however, their side effects might subsequently increase the risks of ICU delirium. Therefore, developing an effective non-pharmacological intervention of preventing delirium among critically mechanical ventilated patients is of clinical relevance. Purposes: To examine the effects of music intervention on reducing delirium in mechanically ventilated critical patients, to determine its beneficial effects on delirium-related outcomes, including sedation time, the duration of mechanical ventilation, and the length of ICU stay, and to compare the change of heart rate variability between groups.

Detailed Description

Delirium is a common acute confusion state among critical patients in intensive care units (ICUs). The symptoms are serious disturbance in mental abilities which may cause inattention, confused thinking, agitated mood, and fluctuated consciousness. Delirium also lead to higher mortality, longer hospital stay, higher cost of healthcare and poor recovery. However, the mechanism of delirium still not fully understand. Imbalanced neurotransmitters may be one of the possible explain for such situation. It is related to increased level of dopamine and acetylcholine deficiency. In addition, the relation between low level of melatonin and postoperative delirium was also reported. Glucocorticoid which represent the stress response is also related to postoperative delirium. Both changes of neurotransmitters and hormone levels would affect sleep-awake cycle. It is observed that patients who is delirium show a relative higher EEG theta power and a reduced alpha power than non-delirious patients. Several modifiable risk factors, such as noise, light, physical restrain, pain, anxiety, and sedatives, may contribute to poor sleep quality or sleep disruption and further delirium occurrence. Effectiveness interventions are extremely important when patients are inevitably exposed to such risk factors.

Pharmacological interventions are rapid and effective way for delirium management. However, the concern about side effect and increased mortality among high risk patients are needed. According to 2018 Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU, non-pharmacological intervention was suggested for delirium management firstly. Non-pharmacological interventions, such as using earplug or eye mask at night, music therapy or early mobilization, should be safe, less side effect and widely applicable for first-line healthcare providers. In addition, multicomponent interventions should be more effective than single component intervention. However, the evidence of direct comparison is limited.

Music intervention is a non-invasive, low-cost and non-pharmacological intervention. Several clinical trials were proved that music therapy could reduce the pain and anxiety among postoperative and old age population for better clinical progress. Listening to soft music can enhance brain alpha wave, and there is a negative correlation between alpha wave of EEG and sympathetic excitation. The preference of music also influences power of alpha wave. Recent studies report that implying music intervention on postoperative patients could lead to fewer acute confusion status, however, the incidence and potential exposed risk factors of delirium between medical and surgical populations were different. The effect of music intervention on medical critical patients and the related mechanism still need further investigation. In addition, whether the multicomponent intervention could obtain greater effect than single component intervention still not ascertained. Furthermore, the evidences of music intervention in decreasing the duration of mechanical ventilation, length of ICU stay, sedation time and mortality were still lacking. The mechanism between music intervention and delirium occurrence also need to further investigate.

Study Groups

Personalized music intervention group

Participants will receive a personalized music session for forty minutes twice a day for consecutive seven days or until discharge from ICU. A total treatment dosage of 560 minutes is required.

Group Type: EXPERIMENTAL

Personalized music

Intervention Type: OTHER

Personalized music intervention will be conducted by research nurse independently. Firstly, the music preference will be confirmed by using predesigned music list. After confirming the music preference, participants will receive a music session for forty minutes through headphone and MP3 player.

Personalized music plus earplug group

Participants will receive a personalized music session for forty minutes twice a day for consecutive seven days or until discharge from ICU. In addition, using earplug during night time sleep. The music intervention total treatment dosage of 560 minutes is required.

Group Type: EXPERIMENTAL

Personalized music plus earplug

Intervention Type: OTHER

Personalized music intervention will be conducted by research nurse independently. Firstly, the music preference will be confirmed by using predesigned music list. After confirming the music preference, participants will receive a music session for forty minutes through headphone and MP3 player. In addition, participants will be worn earplug during night time sleep for decreasing the noise until next morning.

Control group

The control group involves neither music intervention nor using earplug at night.

Group Type: NO_INTERVENTION

No interventions assigned to this group
