Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Dexmedetomidine
Description: A once only intravenous administration of dexmedetomidine as part of a sleep promotion bundle.
Dose: Variable titration per patient based on clinical response, starting at 0.2 and up to 0.7 mcg/kg/hour.
Duration of administration: 9 hours from 21:00 to 06:00 the next morning
Mode of administration: Continuous intravenous infusion.

Sleep Promotion Bundle
Description: A 'Sleep Promotion Bundle Checklist' will be provided to the bedside nurse to address to all the items in the sleep promotion bundle which include:

1. Environmental Modifications/Monitoring

Setup of sleep environment monitor by bedside to assess environmental conditions including ambient light (measured in lux), temperature (in degrees Celsius) and noise (in decibels) which will be recorded minutely throughout the 9-hour intervention period (2100-0600hrs).

Lighting Adjustments (<10lux)
adjusting lights in the patient’s room and surroundings to aim for <10 lux according to ambient light instrument during 9-hour intervention period (2100-0600hrs)
offering an eye mask for the patient if appropriate

Noise Reduction (<40dB)
Aim to keep noise below 40db according to decibel reader instrument
Minimising equipment volume and alarms
Encouraging staff to speak softly and close doors quietly
Offering earplugs for the patient

Temperature Control (20-22 C)
Ensuring room temperature is at recommended temperature range according to temperature monitoring device (20-22 degrees Celsius)
Providing fans or cooling blankets if the patient is too warm
Offering warming blankets to maintain the appropriate temperature

Comfort and Positioning
The goal is to ensure patient comfort. Nurses will adjust pillows and bedding to achieve the most comfortable position for the patient as subjectively reported by patient. There is no specific guideline for proper positioning, and this may vary based on individual needs and clinical judgment or requirement.


2. Scheduling and Routine

Nighttime Routine
Offering warm drinks (if allowed) and assisted with hygiene needs before sleep
Limiting non-essential care and procedures during nighttime hours

Cluster Care Activities
Clustering necessary care activities to minimise disturbances
Scheduling medications, vital sign checks, and other care tasks to allow uninterrupted sleep periods

3. Medications and Interventions

Review Medications
Reviewing the appropriateness of any overnight medications that may disrupt sleep

Pain Management
Assessing and managing the patient’s pain effectively

4. Patient-Centered Care

Sleep Assessments
Conducting baseline sleep assessment to understand the patient’s specific needs and preferences using provided sleep questionnaire

Patient Education
Nurses and research staff will provide education to the patient and their family about the importance of sleep and ways to promote it through the patient information and consent form discussion. The content and duration of this education can be customised based on the patient’s condition and preferences.

5. Additional Considerations

Cultural and Individual Preferences
The bundle acknowledges and respects the patient’s cultural and personal preferences. Staff will incorporate these preferences into sleep hygiene practices. For example, considering cultural norms related to bedtime routines or personal preferences for sleep environment. This will be asked as a question from bedside nurse or research staff and acted on as deemed appropriate by bedside nurse.

Family Involvement
Family members may be actively involved in establishing a calming bedtime routine if available. This may include providing emotional support, assisting with comfort measures, and promoting a soothing environment. This can be organised and as deemed appropriate by bedside nurse.


Strategies used to manage adherence to the interventions:
Monitoring electronic medical records, nursing checklist, staff training and direct supervision from senior nursing.
