ReviewSleep Loss and Circadian Rhythm Disruption in the Intensive Care Unit.
Critical illness is associated with profound sleep disruption. Causality is diverse and includes physiologic, psychological, and environmental factors. There are limited pharmacologic interventions available to treat sleep disturbances in critical illness; however, multidisciplinary strategies that alter the intensive care unit (ICU) environment and cluster care delivery have shown promise in sleep and circadian promotion and delirium reduction. With the appropriate administrative support and involvement of diverse ICU stakeholders, effective strategies could be created, implemented, and maintained to improve sleep disruption in critically ill patients.

Targeted temperature management has an established role in treating the post-cardiac arrest syndrome after out-of-hospital cardiac arrest with an initial rhythm of ventricular tachycardia/ventricular fibrillation. There is less certain benefit if the initial rhythm is pulseless electrical activity/asystole or for in-hospital cardiac arrest. Targeted temperature management may have a role as salvage modality for conditions causing intracranial hypertension, such as traumatic brain injury, hepatic encephalopathy, intracerebral hemorrhage, and acute stroke. There is variable evidence for its use early in these disorders to minimize secondary neurologic injury.

Recent research has identified promising targets for therapeutic interventions aimed at modulating the inflammatory response in sepsis. Herein, the authors describe mechanisms involved in the clearance of pathogen toxin from the circulation and potential interventions aimed at enhancing clearance mechanisms. The authors also describe advances in the understanding of the innate immune response as potential therapeutic targets. Finally, novel potential treatment strategies aimed at decreasing vascular leak are discussed.

ReviewManagement of Infections with Drug-Resistant Organisms in Critical Care: An Ongoing Battle.
Infections with multidrug-resistant organisms (MDROs) are common in critically ill patients and are challenging to manage appropriately. Strategies that can be used in the treatment of MDRO infections in the intensive care unit (ICU) include combination therapy, adjunctive aerosolized therapy, and optimization of pharmacokinetics with higher doses or extended-infusion therapy as appropriate. Rapid diagnostic tests could assist in improving timely appropriate antimicrobial therapy for MDRO infections in the ICU.

During the last 15 years, critical care services provided via telemedicine have expanded to now be incorporated into the care of 13% of patients in intensive care units (ICUs) in the United States. A response to shortfalls in the availability of critical care-trained providers has evolved into integrated programs of ICU care with contributions to improved outcomes through proactive management, population oversight, and standardization of care processes. The most impactful characteristics of successful ICU telemedicine programs are now better understood with more than a decade of national experience and the accrued benefits to health care systems.
