Official title

Comparison of Trazodone vs Quetiapine vs Placebo for the Treatment of ICU Delirium: A Randomized Controlled Trial (The TraQ Study)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The objective of this study is to evaluate the effectiveness of trazodone as compared to quetiapine and placebo, in the management of ICU delirium in adult (\>=18 years old) surgical ICU patients. The investigators will compare outcomes such as delirium incidence and duration, 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, quetiapine, or placebo. The investigators hypothesize participants receiving trazodone will have a shorter duration of delirium, decreased delirium severity, and improved sleep quality compared to participants receiving quetiapine and placebo.
