Effects of Dexmedetomidine in Patients With Agitated Delirium in Palliative Care

The goal of this multi-centre phase I/II open-label, single-arm study is to determine the feasibility, optimal dose, and preliminary efficacy of dexmedetomidine to manage agitated delirium among patients near the end of life followed by a palliative care provider in a non-monitored setting. Fifty patients will receive dexmedetomidine (0.4 mcg/kg/hour, titrated up to 1.0 mcg/kg/hour) subcutaneously. Feasibility (recruitment rate, cost), safety (rate of adverse events), dosing, and preliminary efficacy (agitation, delirium severity) will be measured.

Trazodone vs. Quetiapine for the Treatment of ICU Delirium

This is a single-center, prospective observational pilot study. The objective of this study is to evaluate the effectiveness of trazodone as compared to quetiapine, in the management of ICU delirium in adult (\>=18 years old) surgical and medical ICU patients. The investigators will compare outcomes such as delirium duration, delirium-free days, coma-free days, in-hospital mortality, 28-day mortality, hospital length of stay (LOS), ICU LOS, mechanical ventilator days, complications, adverse effects, rescue medication use, delirium symptom severity, sleep duration, and sleep quality among participants receiving trazodone or quetiapine. The investigators hypothesize participants receiving trazodone will be associated with a shorter duration of delirium, decreased delirium severity, and improved sleep quality compared to participants receiving quetiapine.
