Monitoring of nighttime EEG slow‐wave activity during dexmedetomidine infusion in patients with hyperactive ICU delirium: An observational pilot study

Background The disturbance of sleep has been associated with intensive care unit (ICU) delirium. Monitoring of EEG slow‐wave activity (SWA) has potential in measuring sleep quality and quantity. We investigated the quantitative monitoring of nighttime SWA and its association with the clinical evalua...

Description
Summary:Background The disturbance of sleep has been associated with intensive care unit (ICU) delirium. Monitoring of EEG slow‐wave activity (SWA) has potential in measuring sleep quality and quantity. We investigated the quantitative monitoring of nighttime SWA and its association with the clinical evaluation of sleep in patients with hyperactive ICU delirium treated with dexmedetomidine. Methods We performed overnight EEG recordings in 15 patients diagnosed with hyperactive delirium during moderate dexmedetomidine sedation. SWA was evaluated by offline calculation of the C‐Trend Index, describing SWA in one parameter ranging 0 to 100 in values. Average and percentage of SWA values
