Study summary

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.

What researchers measure

Primary outcomes

  1. the number of arousals

    arousals will be scored during the sleep periods and the index - arousals per hour of sleep - will be counted

    Time frame: per hour of sleep

Secondary outcomes

  1. total sleep time

    total sleep time during 24 hour period

    Time frame: 24 hours

  2. N1 sleep

    N1 sleep stage will be scored during sleep periods (dag sleep/night sleep)and the percent of N1 sleep will be counted

    Time frame: 24 hours

  3. N2 sleep

    N2 sleep stage will be scored during sleep periods and the percent of N2 sleep will be counted

    Time frame: 24 hours

  4. N3 sleep

    N3 sleep stage will be scored during sleep periods and the percent of N3 sleep will be counted

    Time frame: 24 hours

  5. REM sleep

    REM sleep will be scored during sleep periods and the percent of REM sleep will be counted

    Time frame: 24 hours
