Poor sleep is common in intensive care unit (ICU) patients. However, the risk factors and the consequences of sleep abnormalities on the outcome are not well established. This all the more true that many studies have not been based on polysomnography and have been conducted in patients receiving sedation.
The aims of our study were: 1) to identify risk factors of sleep abnormalities in non-sedated ICU patients 2) to describe the consequences of sleep disturbances on the outcome.
no sedation for >24h,
sedation level < 3 on the Ramsay scale,
expected remaining ICU stay >48 hours,
morphine < 0.01 mg/kg/min,
norepinephrine < 0.3µg/Kg/min.
A 17h polysomnography was performed on the day of inclusion. Patients completed the Hospital and Anxiety depression scale at ICU and hospital discharge and at Day-90.
Even in critically-ill patients who do not receive sedation, sleep quantity and architecture are severely altered. Comorbidities, severity of illness and human interventions negatively affect sleep quantity and architecture.
