It is my understanding that patients still experience sleep/wake cycles while sedated on propofol. However, I am having difficulty finding more information about this. I am curious if measures can be taken when a patient is sedated to prevent/minimize/correct ICU psychosis in patients who have been sedated for long periods of time and aren't receiving the normal cues for the sleep/wake cycle. I've already had patients moved to the east side of the unit to get morning sun, and tried other cues to encourage less sleep during the day, and I know night shift tries to make things as quiet and restful during the night as possible (though I know that is difficult or impossible many times). We also do sedation holidays every shift if stable enough.
Your thoughts and info are appreciated!
