Investigation of Sleep in the Intensive Care Unit
In Brief
A Phase 2 clinical trial evaluating Dexmedetomidine and Placebo for Delirium and Sleep. Completed, enrolled 522 participants across 1 site.
Detailed Summary
Sleep deprivation is common and often severe in critically ill patients cared for in intensive care units (ICUs) and is hypothesized to be a modifiable risk factor for delirium, which in turn is hypothesized to be a modifiable risk factor for long-term cognitive disability following recovery from critical illness. Dexmedetomidine (Dex) reduces the incidence of delirium in ICU patients by unknown mechanisms. The Investigation of Sleep in the Intensive Care Unit (ICU-SLEEP) Trial aims to determine whether Dex reduces delirium by improving sleep, whether a low- and/or very-low dose continuous infusion of Dex increases delirium-free days more, and the relationship between sleep deprivation in the ICU to long-term cognitive outcomes.

Interventions
"Dex (Precedex, Dexmedetomidine HCl Injection) is produced by Pfizer Inc, NY, Ny (formerly Hospira). Dex is a white or almost white powder that is freely soluble in water and has a pKa of 7.1. Its partition coefficient in-octanol: water at pH 7.4 is 2.89. Dex is supplied as a clear, colorless, isotonic solution with a pH of 4.5 to 7.0. Each mL contains 118 mcg of dexmedetomidine hydrochloride equivalent to 100 mcg (0.1mg) of dexmedetomidine and 9 mg of sodium chloride in water. The solution is preservative-free and contains no additives or chemical stabilizers. The MGH Pharmacy currently obtains Dex from the supplier as a solution in 50 mL clear-glass bottles, as a clear liquid, at a concentration of 4mcg/mL."

It is a parenteral solution containing sodium chloride in water for injection intended for intravenous administration. Each 100 mL of 0.9% Sodium Chloride Injection, USP contains 900 mg sodium chloride in water for injection. Electrolytes per 1000 mL: sodium (Na+ ) 154 mEq; chloride (Cl- ) 154 mEq. The osmolarity is 308 mOsmol/L (calc.). The pH is 5.6 (4.5 to 7.0). This solution contains no bacteriostat, antimicrobial agent or added buffer and is intended only as a single-dose injection. When smaller doses are required, the unused portion should be discarded. 0.9% Sodium Chloride Injection, USP is a parenteral fluid and electrolyte replenisher. Sodium Chloride, USP is chemically designated NaCl, a white crystalline powder freely soluble in water. Water for Injection, USP is chemically designated H2O."
