“…Several studies have already performed PSG in ICU patients who are critically ill. Nevertheless, unlike previous reports showing a link between subjective sleep deprivation and delirium [ 14 , 15 , 17 ], the relationship between delirium and objectively measured sleep fragmentation is inconsistent across studies [ 8 , 13 , 28 , 30 ]. Furthermore, one study indicated that sleep in the ICU was atypical regardless of clinical delirium status; the usual scoring method frequently failed to determine sleep stages [ 28 ].…”

“…Previous studies using PSG in the ICU have emphasized REM deprivation in patients with delirium [ 8 , 13 , 30 ]. Although REM deprivation in the two patients with delirium also occurred in this study, the uniqueness of REM deprivation in patients with delirium was not noticeable, since REM deprivation occurred in approximately 40% of the patients without delirium in.…”

“…Instead, of note, pronounced nocturnal sleep deprivation was observed in patients with delirium in the present study. Some studies have reported that TST at night tends to be short in patients with delirium [ 13 , 30 ], and another study indicated that TST at night was comparable regardless of delirium status [ 48 ]. The reason for the difference between these previous studies and this study is unclear.…”

“…Yet, given the potential discrepancy between sleep assessment from the patient’s or nurse’s perspective and objectively recorded sleep measures in the ICU [ 20 , 21 , 22 ], research to clarify the relationship between objective sleep evaluation and delirium is warranted. Objectively measured sleep fragmentation has been observed in the ICU using polysomnography (PSG), which is the gold standard in sleep evaluation [ 8 , 13 , 21 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. Several studies have already performed PSG in ICU patients who are critically ill.…”

The relationship between polysomnography-based objective sleep and delirium in the intensive care unit (ICU) is inconsistent across studies, suggesting limitations in manually determining the sleep stage of critically ill patients. We objectively measured 24-h sleep using a single-channel electroencephalogram (SleepScope [SS]) and an under-mattress sleep monitor (Nemuri SCAN [NSCAN]), both of which have independent algorithms that automatically determine sleep and wakefulness. Eighteen patients (median age, 68 years) admitted to the ICU after valvular surgery or coronary artery bypass grafting were included, and their sleep time was measured one day after extubation. The median total sleep times (TSTs) measured by SS (TST-SS) and NSCAN were 548 (48–1050) and 1024 (462–1257) min, respectively. Two patients with delirium during the 24-h sleep measurement had very short TST-SS of 48 and 125 min, and the percentage of daytime sleep accounted for >80% in both SS and NSCAN. This preliminary case series showed marked sleep deprivation and increased rates of daytime sleeping in ICU patients with delirium. Although data accuracy from under-mattress sleep monitors is contentious, automated algorithmic sleep/wakefulness determination using a single-channel electroencephalogram may be useful in detecting delirium in ICU patients and could even be superior to polysomnography.

They include: sleeplessness, poor sleep quality, daytime sleepiness, and lack of sleep continuity (difficulty in initiating sleep, frequent nocturnal awakenings, and early morning awakening).…”

Background Sleep is essential for full mental and physical renewal. Cardiac surgery improves the life expectancy and quality. But unfortunately, some patients lacked that merit as they suffered sleep disturbance. We used validated questionnaire applied to 153 cardiac surgery patients to assess the sleep disturbances after surgery. Results About 70 (45.8%) had valve procedure, 55 (36%) had revascularization, 19 (12.4%) had both procedures and 9 (5.8%) had other procedures. The majority had no post-operative bleeding nor infection. About 78% had sleeping difficulty for one month. About 50% used different medications to fall asleep, mostly analgesics. About 76% slept after 2–6 h irrespective of sleep quality. Some patients had poor sleep quality in the form of nightmares and night terrors. Conclusion Sleep quality was disturbed immediately following cardiac surgery. There was a reduction of night sleep compensated by increased daytime sleepiness. These changes almost reverted one month after surgery.
