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.
