In population of intensive care unit (ICU), most studies compared atypical antipsychotics such as quetiapine with the traditional haloperidol in delirious patients of various forms and etiologies. The role of such agents in patients with hyperactive is not fully understood.
This study compares the effectiveness of quetiapine with haloperidol in treating the hyperactive form of delirium in terms of their effects on morbidity, length of stay in the intensive care unit, and mortality in critically ill patients.
A common complication in the intensive care unit (ICU) that has recently been identified is delirium. Defining delirium as a "sudden deterioration in attention, awareness, and cognition, which is not explained by any pre-existing neurocognitive disorder, but because of another medical condition," the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) clarified the definition of delirium.
A dibenzothiazepine derivative with a novel and distinctive pharmacologic profile is quetiapine. The limbic system is overactive in delirium, which is one of its pathophysiologies. By obstructing the mesolimbic dopamine D2 receptors specifically, quetiapine may be able to regulate this hyperactivity.
The objective of this study is to compare the effectiveness of quetiapine with haloperidol in treating the hyperactive form of delirium in terms of their effects on morbidity, length of stay in ICU, and mortality in critically ill patients.
