Summary
Sleep quality in intensive care units is negatively impacted by noise, light, age, alcohol, benzodiazepine use, and comorbidities. Sleepiness decreased by the end of the hospital stay.
Area of Science:
- Intensive Care Medicine
- Sleep Medicine
- Patient Experience
Background:
- Sleep quality is crucial for patient recovery in intensive care units (ICUs).
- Factors affecting sleep in ICUs are not fully understood.
- Poor sleep can lead to adverse patient outcomes.
Purpose of the Study:
- To assess sleep quality among ICU patients.
- To identify factors influencing sleep quality in the ICU environment.
- To evaluate changes in sleepiness throughout the patient's stay.
Main Methods:
- A descriptive cross-sectional study involving 129 patients in a tertiary hospital's Intensive Care Medicine department.
- Data collected using a modified Freedman questionnaire, including demographic and clinical variables.
- Statistical analyses included Wilcoxon test, Spearman correlation, and multiple regression.
Main Results:
- Noise and light were identified as major disturbances, with significant impact from nursing activities and care.
- Multivariate analysis revealed age, daily alcohol intake, benzodiazepine use, and comorbidities negatively affected sleep quality.
- Patients reported reduced sleepiness at discharge compared to earlier periods.
Conclusions:
- Nursing activities and environmental factors like noise and light significantly disrupt ICU sleep.
- Patient-specific factors including age, alcohol consumption, benzodiazepine use, and comorbidities are critical determinants of poor sleep quality.
- Interventions targeting these factors may improve patient sleep and recovery in the ICU.

01:13Insufficient Sleep and Sleep Deprivation
317
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

01:24Substance Use Disorders Affecting Sleep
241
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

01:19Management of Insomnia
351
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

01:23Acute Respiratory Failure-IV
289
Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...

01:18Nightmares and Night Terrors
193
Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

01:27Insomnia
193
Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.
