Brief Summary:
The primary purpose of the study is to evaluate whether dexmedetomidine is effective in treating agitated delirium of non-intubated ICI patients
Detailed Description:
Delirium during intensive care unit (ICU) stay is frequent and associated with significant morbidity, mortality and healthcare related costs. International guidelines suggest its prevention. However, curative treatment remains unclearly established. Despite a non-unequivocal literature, haloperidol is the first line recommended neuroleptic. Dexmedetomidine, an alpha2-adrenergic receptors agonist has shown its efficiency in the treatment of delirium in intubated patients but also in its prevention. Dexmedetomidine represents a widely used alternative to haloperidol. Only few studies have compared the efficacy of dexmedetomidine in non-intubated ICU patients as a first line curative treatment of delirium. Main objective of 4D trial is to demonstrate that dexmedetomidine decreases delirium duration compared to placebo.
The 4D trial is an investigator-initiated, prospective, multicenter, randomized, double-blinded, two-arm trial, randomizing 300 non-intubated ICU patients with diagnosis of agitated delirium to receive dexmedetomidine or placebo as a cure. The primary outcome measure is a composite of duration of agitation or delirium or the use of intubation with deep sedation and mechanical ventilation. Secondary outcomes include mortalities at 7 and 28 days, ICU length of stay and occurrence of adverse effects. The sample size will allow the detection of a 50% decrease of agitation duration (120 minutes), of an absolute reduction of delirium duration (1 day) and of a 50% relative decrease of intubation and mechanical ventilation, with a type 1 error rate of 1.8 % (error risk inflation due to components of composite) and power of 90 %, assuming a 15 % incidence of intubation and mechanical ventilation requirements, an agitation duration of 240 minutes and a delirium duration of 3 days. One hundred and 10 patients by group will be needed. A intermediate analysis is scheduled and requires the inclusion of 150 patients in each group.
The 4D trial may provide important data on the safety of commonly used sedative dexmedetomidine and could have a significant impact on future treatment of non-intubated ICU patients presenting with agitated delirium.
