Sleep Investigation in Respirator Treated ICU Patients: the Importance of Intensive Environment
Sleep investigation in respirator treated ICU patients: the importance of intensive environment.
Sleep disturbances in the ICU seem to lead to development of delirium, prolonged ICU stay and increased mortality.
The hypothesis of this study is: minimizing of disturbing factors in the ICU, such as noise, light, therapeutic and diagnostic procedures between 10 p.m. and 6 a.m. will improve sleep quality in respirator treated ICU patients.
Methods: randomized interventional study. 48-hour polysomnographic sleep measurement acc. AASM's standard in 46 awake respirator treated patients: 24 hours under ordinary circumstances and 24 hours under the protocol 'Quiet in the room' between 10 p.m. and 6 a.m. after randomization.
|Study Design:||Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Prevention
- the number of arousals [ Time Frame: per hour of sleep ]arousals will be scored during the sleep periods and the index - arousals per hour of sleep - will be counted
- total sleep time [ Time Frame: 24 hours ]total sleep time during 24 hour period
- N1 sleep [ Time Frame: 24 hours ]N1 sleep stage will be scored during sleep periods (dag sleep/night sleep)and the percent of N1 sleep will be counted
- N2 sleep [ Time Frame: 24 hours ]N2 sleep stage will be scored during sleep periods and the percent of N2 sleep will be counted
- N3 sleep [ Time Frame: 24 hours ]N3 sleep stage will be scored during sleep periods and the percent of N3 sleep will be counted
- REM sleep [ Time Frame: 24 hours ]REM sleep will be scored during sleep periods and the percent of REM sleep will be counted
