Sleep Promotion in Critically Ill and Injured Patients Cared for in the Intensive Care Unit
Sleep deprivation in healthy volunteers is associated with immune dysfunction. This adverse effect of sleep deprivation likely occurs in patients suffering from acute injury and critical illness requiring intensive care unit (ICU) admission. Studies have demonstrated that sleep in ICU patients is highly abnormal. The global hypothesis for this proposal is that a strategy to promote sleep in ICU patients will increase time in rapid eye movement (REM) and slow wave sleep (SWS). This three phase proposal examines the feasibility of a sleep promotion strategy for injured and critically ill patients in the ICU.
Phase I (Development and Training): Develop an intervention manual for sleep promotion, Sleep Enhancement Program (SEP), and train ICU staff.
Phase II (Validation and Safety): Implement SEP and test for protocol fidelity and safety.
Phase III (Efficacy): Conduct a pilot trail to determine efficacy of SEP to improve SWS in ICU patients.
