Sleep disturbances and fatigue are significant problems for critically ill patients. Existing sleep disorders, underlying medical/surgical conditions, environmental factors, stress, medications, and other treatments all contribute to a patient's inability to sleep. Sleep disturbance and debilitating fatigue that originate during acute illness may continue months after discharge from intensive care units (ICUs). ⋯ A multidisciplinary approach that incorporates assessment of sleep disturbances and fatigue, environmental controls, appropriate pharmacologic management, and educational and behavioral interventions is necessary to reduce the impact of sleep disturbances and fatigue in ICU patients. Nurses are well positioned to identify issues in their own units that prevent effective patient sleep. This article will discuss the literature related to the occurrence, etiology, and risk factors of sleep disturbance and fatigue and describe assessment and management options in critically ill adults.

A significant portion of critical care patients experience delirium. This form of acute brain dysfunction is associated with increased hospital stay, increased mortality, and greater long-term cognitive deficits. ⋯ This article will provide an overview of delirium and describe an interdisciplinary model of care combining multiple evidence-based practice strategies that nurses can and should use to help systematically reduce modifiable delirium risk factors. In addition, this article will provide an overview of recent reports concerning pharmacologic management of delirium in the intensive care unit.

Opioid tolerance resulting from long-term opioid consumption for chronic pain or from substance use disorder adds a layer of complexity to managing pain in the critical care setting. This article discusses similarities and differences of these 2 conditions. ⋯ An overview of the neurophysiology of pain and substance use disorder is presented. Practical clinical suggestions are given to assist the critical care nurse in caring for these complex patients.

Symptoms are subjective patient experiences that may negatively impact the patient's hospitalization, treatment plan, and quality of life. Critically ill patients frequently experience nausea, vomiting, and diarrhea related to underlying disease, procedures, and medical interventions (eg, medication, enteral feeding, surgery). ⋯ Unfortunately, little evidence is available to guide assessment of nausea, vomiting, and diarrhea in critically ill nonverbal patients. Understanding the disease processes, medical treatments, and pathophysiology of these symptoms will assist the critical care nurse in the anticipation of symptoms and development of a proactive plan to alleviate the symptom-associated discomfort.
