Brief Summary
The primary aim of the DahLIA trial is to determine, in patients with ICU-associated delirium and agitation who are otherwise pathophysiologically stable (as defined), the number of ventilator-free ho...
Eligibility Criteria
Inclusion
- Patients will be eligible for the study if, in the opinion of the treating clinician, they continue to require mechanical ventilation only because their degree of agitation requires such a high dose of sedative medication (midazolam or propofol, the only commonly used specific sedatives in our unit) that extubation is not possible, AND in the opinion of their treating intensivist their agitation is so severe as to make lessening their sedation unsafe.
- These criteria will be objectively quantified as follows:
- they have required either mechanical restraint and/or anti-delirium or sedative medication in the 4 hours prior to seeking consent AND
- their Confusion Assessment Method for the ICU (CAM-ICU) test is positive for delirium in the 4 hours prior to seeking consent AND
- their Motor Activity Assessment Scale (MAAS) score is 5 or more in the 4 hours prior to seeking consent, confirming psychomotor agitation AND
- their SOFA score is less than or equal to 5 in the 4 hours prior to seeking consent, predicting a mortality or around 5%.
Exclusion
- Age less than 18 years old
- Pregnancy or breastfeeding
- Advanced dementia (in the premorbid state requiring professional nursing care)
- Open or closed head injury
- Death is deemed imminent and inevitable
- The patient has previously been enrolled in the DahLIA study
- Patients who could not be extubated, or who would be intubated within the following 48 hours, even if delirium or agitation were corrected. This will include:
- Patients receiving high dose opioid for analgesia (not sedation) ( \> 40 mg/morphine/day)
- Patients shortly to return to the operating theatre
- Patients undergoing repeated invasive procedures, in whom it is desirable to maintain deep sedation
- Patients likely to require ongoing airway protection or control, or ventilatory support (for example, spinal patients with an inadequate vital capacity)
- Known allergy to haloperidol or alpha 2 agonists
