Seriously Ill Patients

Sleep disturbances are common among patients admitted to the intensive care unit (ICU); however, these issues tend to receive less attention because critical care is prioritized in seriously ill patients. Recent studies have reported that sleep disturbances in patients admitted to the ICU are associated with delirium, weakened immunity, long-term cognitive decline, and persistent sleep disorders. Sleep disturbances in the ICU are attributable to the disease per se and also to the ICU environment that is not conducive to good sleep. Continuous exposure to light and noise are major environmental risk factors that disrupt the circadian rhythm and interfere with deep sleep. Sleep analysis using polysomnography in patients admitted to the ICU typically reveals increase in sleep latency, sleep fragmentation, and decreased stage N3 and rapid eye movement sleep, which are associated with poor prognosis even in patients with severe neurological conditions, including traumatic brain injury and intracranial hemorrhage. Polysomnography is the gold standard for objective evaluation of sleep; however, its applicability is limited in ICU settings, and novel methods such as continuous electroencephalographic spectral analysis and actigraphy have recently been proposed in clinical practice. Efforts to reduce nighttime light and noise (which are modifiable environmental factors) can improve sleep quality. In this article, the author reviews the studies that discuss characteristics of sleep disturbances, the associated risk factors and their correlation with prognosis among patients admitted to the ICU, as well as possible strategies to improve sleep quality in this patient population.

Dexmedetomidine Infusion

Abstract Background Patients admitted to the intensive care unit (ICU) after surgery often develop sleep disturbances. The authors tested the hypothesis that low-dose dexmedetomidine infusion could improve sleep architecture in nonmechanically ventilated elderly patients in the ICU after surgery. Methods This was a pilot, randomized controlled trial. Seventy-six patients age 65 yr or older who were admitted to the ICU after noncardiac surgery and did not require mechanical ventilation were randomized to receive dexmedetomidine (continuous infusion at a rate of 0.1 μg kg−1 h−1; n = 38) or placebo (n = 38) for 15 h, i.e., from 5:00 pm on the day of surgery until 8:00 am on the first day after surgery. Polysomnogram was monitored during the period of study-drug infusion. The primary endpoint was the percentage of stage 2 non–rapid eye movement (stage N2) sleep. Results Complete polysomnogram recordings were obtained in 61 patients (30 in the placebo group and 31 in the dexmedetomidine group). Dexmedetomidine infusion increased the percentage of stage N2 sleep from median 15.8% (interquartile range, 1.3 to 62.8) with placebo to 43.5% (16.6 to 80.2) with dexmedetomidine (difference, 14.7%; 95% CI, 0.0 to 31.9; P = 0.048); it also prolonged the total sleep time, decreased the percentage of stage N1 sleep, increased the sleep efficiency, and improved the subjective sleep quality. Dexmedetomidine increased the incidence of hypotension without significant intervention. Conclusions In nonmechanically ventilated elderly patients who were admitted to the ICU after noncardiac surgery, the prophylactic low-dose dexmedetomidine infusion may improve overall sleep quality.

Improve Sleep Quality

Patients in intensive care units (ICU) are at risk of sleep disorders. Patients in Intensive Care Unit (ICU) with a history of cardiovascular disease, for example Coronary Heart Disease if have poor sleep quality can affect the healing process. This study aims to identify and analyze the positive effects of using Eyemask, Earplug and Dhikr Therapy on sleep quality in ICU patients. The research methods used are literature reviews on national and international articles published in the last 5-10 years. The use of Eye Mask and Ear Plug therapy and Dhikr Therapy can be applied as a supportive therapy for patients with sleep disorders in intensive care unit(ICU).
