Study Details

Brief summary:

The purpose of this study is to determine the feasibility of conducting a randomized controlled trial (RCT) with melatonin for treatment of delirium in critically ill adult patients. From a feasibility perspective, the investigators believe that the proposed design will achieve the minimum enrollment rate necessary to conduct a future RCT on a larger scale.
