Effect of Sleep on the Recovery of Patients Admitted to the ICU

Summary

The investigators plan to create several sleep/circadian rhythm friendly rooms within the medical intensive care unit to determine if decreasing sleep fragmentation effects recovery in patients hospitalized in the ICU.

Description

Critically ill patients are known to suffer from severely fragmented sleep with a predominance of stage I sleep and a paucity of slow wave and REM sleep. The causes of this sleep disruption include the intensive care unit (ICU) environment, medical illness, psychological stress, and many of the medications and other treatments used to help those who are critically ill. Surveys have identified poor sleep as one of the most frequent complaints among patients who have survived a critical illness. Patients in medical, cardiac, and surgical ICUs almost uniformly have fragmented sleep.

Although illness, pain, and medications contribute to sleep disruption in ICU patients, the primary factor causing sleep disruption had been thought to be the ICU environment. Noise from various sources, including ventilators, alarms, television, phones, beepers, and conversation, have all been purported to disturb sleep in the ICU. Patients have reported that noise, specifically talking, is a frequent cause of sleep disruption in the ICU. Several studies have confirmed that peak noise levels in ICUs are far in excess of 45 dB during the day and 35 dB at night, which are the recommendations of the Environmental Protection Agency for peak noise levels in the ICU.

The clinical importance of this type of sleep disruption in critically ill patients, however, is not known. The investigators hope to determine if placing patients in sleep/circadian rhythm friendly rooms will enable them to achieve better sleep, suffer from decreased delirium, and have improved recovery from their critical illness.

Medical and Biotech [MESH] Definitions

The state of being deprived of sleep under experimental conditions, due to life events, or from a wide variety of pathophysiologic causes such as medication effect, chronic illness, psychiatric illness, or sleep disorder.

Abnormal sleep-wake schedule or pattern associated with the CIRCADIAN RHYTHM which affect the length, timing, and/or rigidity of the sleep-wake cycle relative to the day-night cycle.

Dyssomnias associated with disruption of the normal 24 hour sleep wake cycle secondary to travel (e.g., JET LAG SYNDROME), shift work, or other causes.

A broad category of sleep disorders characterized by either hypersomnolence or insomnia. The three major subcategories include intrinsic (i.e., arising from within the body) (SLEEP DISORDERS, INTRINSIC), extrinsic (secondary to environmental conditions or various pathologic conditions), and disturbances of circadian rhythm. (From Thorpy, Sleep Disorders Medicine, 1994, p187)

A nonapeptide that is found in neurons, peripheral organs, and plasma. This neuropeptide induces mainly delta sleep in mammals. In addition to sleep, the peptide has been observed to affect electrophysiological activity, neurotransmitter levels in the brain, circadian and locomotor patterns, hormonal levels, psychological performance, and the activity of neuropharmacological drugs including their withdrawal.
