简要总结
Sleep deprivation is known to affect brain function but is often ignored in the sickest patients including those in the intensive care unit after major surgery. In these patients, the levels of melatonin can also be altered. Melatonin is a hormone secreted in the brain that maintains the body's sleep-wake, or circadian, cycle. The investigators want to test whether improving sleep quality affects the risk of developing confusion (delirium) in patients having clot removed from their lung (open heart surgery). In order to improve sleep quality, the investigators will conduct a study of Ramelteon, a medication that mimics the activity of melatonin and measure its effects on levels of melatonin and monitor sleep.

结局指标
主要结局
Duration of Delirium
时间窗: Twice daily for up to 10 days
Measured twice daily during the ICU stay using the Confusions Assessment Method instrument.
Total Duration of Sleep
时间窗: Daily for up to 10 days
Participants wore an actigraphy device on their wrist for the duration of their ICU stay. This device continuously measures activity, and thus estimates sleep time.
次要结局
- Number of Participants With Delirium(Twice daily for up to 10 days)
- Measures of the Sound Levels in the Patient's Room(3 days)
- Average Daily Critical Care Pain Observation Tool (CPOT)(10 days)
- Length of Hospital Stay(Duration of hospital admission)
- Length of ICU Stay(Duration of hospital admission)
- Measures of Light Quality in the Patient's Room(3 days)
