ReviewSleep Loss in the Hospitalized Patient and Its Influence on Recovery From Illness and Operation.
Adequate sleep is essential to health and well-being. Adverse effects of sleep loss are evident acutely and are cumulative in their effect. ⋯ Such effects are counterproductive to recovery from illness and operation, yet hospitalization challenges sleep through the anxieties, discomforts, and sleep environmental challenges faced by patients, the inadequate attention given to the needs of patients with preexisting sleep disorders, and the lack of priority these issues receive from hospital staff and their leaders. Mitigation of the adverse effects of noise, light, uncomfortable bedding, intrusive observations, anxiety, and pain together with attention to specific sleep needs and monitoring of sleep quality are steps that would help address the issue and potentially improve patient outcomes.

ReviewThe Neural Circuits Underlying General Anesthesia and Sleep.
General anesthesia is characterized by loss of consciousness, amnesia, analgesia, and immobility. Important molecular targets of general anesthetics have been identified, but the neural circuits underlying the discrete end points of general anesthesia remain incompletely understood. General anesthesia and natural sleep share the common feature of reversible unconsciousness, and recent developments in neuroscience have enabled elegant studies that investigate the brain nuclei and neural circuits underlying this important end point. ⋯ Conversely, arousal circuits that promote wakefulness are involved in anesthetic emergence and activating them can induce emergence and accelerate recovery of consciousness. Modern neuroscience techniques that enable the manipulation of specific neural circuits have led to new insights into the neural circuitry underlying general anesthesia and sleep. In the coming years, we will continue to better understand the mechanisms that generate these distinct states of reversible unconsciousness.

One-lung ventilation in children continues to present technical and sometimes physiologic challenges to the clinician. The rarity of these cases at any single institution, however, has led to very few prospective trials to guide best practices. As a result, most clinicians continue to be guided by local tradition and preference. ⋯ The Arndt bronchial blocker continues to represent the most well documented of these devices. Additionally, recent advances have occurred in our understanding of the relevant anatomic constraints of the lower pediatric airway. This review is intended to provide a comprehensive and practical update to practicing pediatric anesthesiologists to further their understanding of the modern practice of one-lung ventilation for thoracic surgery in children.

ReviewIntegrating Sleep Knowledge Into the Anesthesiology Curriculum.
There is common ground between the specialties of anesthesiology and sleep medicine. Traditional sleep medicine curriculum for anesthesiology trainees has revolved around the discussion of obstructive sleep apnea (OSA) and its perioperative management. ⋯ The range of topics include not only the basics of the physiology of sleep and sleep-disordered breathing (eg, OSA and central sleep apnea) but also insomnia, sleep-related movement disorders (eg, restless legs syndrome), and disorders of daytime hypersomnolence (eg, narcolepsy) in the perioperative and chronic pain settings. Awareness of these topics is relevant to the scope of knowledge of anesthesiologists as perioperative physicians as well as to optimal sleep health and physician wellness and increase consideration among current anesthesiology trainees for the value of dual credentialing in both these specialties.

The negative impacts of sleep deprivation and fatigue have long been recognized. Numerous studies have documented the ill effects of impaired alertness associated with the disruption of the sleep-wake cycle; these include an increased incidence of human error-related accidents, increased morbidity and mortality, and an overall decrement in social, financial, and human productivity. ⋯ Moreover, the rapid and unprecedented spread of coronavirus disease 2019 (COVID-19) pandemic significantly increased the level of anxiety and stress on the physical, psychological, and the economic well-being of the entire world, with heightened effect on frontline clinicians. Additional studies are necessary to evaluate the emotional and physical toll of the pandemic in clinicians, and its impact on sleep health, general well-being, and performance.
