Brief description of media:

Over the past decade, survival from critical illness has dramatically increased due to a better understanding of the pathophysiological mechanisms of disease, improved treatment strategies and advancements in medical technology. Several studies have shown improved survival and long-term outcomes in survivors of critically illness. However, surviving the intensive care unit (ICU) stay is just the start of a long road to recovery for a majority of these patients. The discharge from the ICU opens the path to a long journey of challenging physical rehabilitation, mood disorders, cognitive impairment, psychological distress, financial hardship, and caregiver burden and burnout.

In recent years there has been a growing recognition of impairments that affect the physical, psychological, social, and emotional aspects of the individual after ICU discharge that may adversely impact daily functioning and quality of life (QOL). Recently, the term “post-intensive care syndrome” (PICS) is used to describe any new or worsening impairments in physical, cognitive, or mental health status arising after critical illness and persisting beyond the acute care hospitalization.1 PICS may persist for months to years after hospital discharge. Most impairments will diminish with time, but some may linger on until the patient’s actual demise. This chapter will explore in detail the different domains affected in PICS, its impact on the individual and society, and offer insights into future developments.

Session Objective: Construct a safe and effective medication regimen for the management of pain and agitation in critically ill adults, consistent with ICU PAD Guidelines recommendations.

Brief description of media:

Post–intensive care syndrome (PICS) is a myriad of chronically debilitating symptoms, often including chronic pain, associated with prolonged ICU care. Though the exact mechanism of chronic post-ICU pain is unknown, it is postulated that the severity of inflammation associated with many forms of critical illness leads to chronic pain in patients long after resolution of their acute critical illness. Increasing emphasis on long-term outcomes of ICU survivors makes prevention of chronic pain and PICS a priority for multidisciplinary ICU teams. This article discusses the prevalence and mechanisms of chronic post-ICU pain and suggests strategies to reduce the impact of chronic pain on quality of life in ICU survivors.

Flolan (iFLO) and Veletri (iVEL) are 2 inhaled epoprostenol formulations. There is no published literature comparing these formulations in critically ill patients with refractory hypoxemia.

Objective: To compare efficacy, safety, and cost outcomes in patients who received either iFLO or iVEL for hypoxic respiratory failure. Methods: This was a retrospective, single-center analysis of adult, mechanically ventilated patients receiving iFLO or iVEL for improvement in oxygenation. The primary end point was the change in the PaO2/FiO2 ratio after 1 hour of pulmonary vasodilator therapy. Secondary end points assessed were intensive care unit (ICU) length of stay (LOS), hospital LOS, duration of study therapy, duration of mechanical ventilation, mortality, incidence of adverse events, and cost.

Results: A total of 104 patients were included (iFLO = 52; iVEL = 52). More iFLO patients had acute respiratory distress syndrome compared with the iVEL group (61.5 vs 34.6%; P = 0.01). There was no difference in the change in the PaO/FiO ratio after 1 hour of therapy (33.04 ± 36.9 vs 31.47 ± 19.92; P = 0.54) in the iFLO and iVEL groups, respectively. Patients who received iVEL had a shorter duration of mechanical ventilation (P < 0.001) and ICU LOS (P < 0.001) but not hospital LOS (P = 0.86) and duration of therapy (P = 0.36). No adverse events were attributed to pulmonary vasodilator therapy, and there was no difference in cost.

Conclusions: We found no difference between iFLO and iVEL when comparing the change in the PaO/FiO ratio, safety, and cost in hypoxic, critically ill patients. There were differences in secondary outcomes, likely a result of differences in underlying indication for inhaled epoprostenol.

The American Psychological Association (APA) developed this guideline to provide recommendations on psychological and pharmacological treatments for post-traumatic stress disorder (PTSD) in adults.

Brief description of media:

Objective: To update and expand the 2013 Clinical Practice Guidelines for the Management of Pain, Agitation, and Delirium in Adult Patients in the ICU.

Design: Thirty-two international experts, four methodologists, and four critical illness survivors met virtually at least monthly. All section groups gathered face-to-face at annual Society of Critical Care Medicine congresses; virtual connections included those unable to attend. A formal conflict of interest policy was developed a priori and enforced throughout the process. Teleconferences and electronic discussions among subgroups and whole panel were part of the guidelines’ development. A general content review was completed face-to-face by all panel members in January 2017.

Methods: Content experts, methodologists, and ICU survivors were represented in each of the five sections of the guidelines: Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption). Each section created Population, Intervention, Comparison, and Outcome, and nonactionable, descriptive questions based on perceived clinical relevance. The guideline group then voted their ranking, and patients prioritized their importance. For each Population, Intervention, Comparison, and Outcome question, sections searched the best available evidence, determined its quality, and formulated recommendations as “strong,” “conditional,” or “good” practice statements based on Grading of Recommendations Assessment, Development and Evaluation principles. In addition, evidence gaps and clinical caveats were explicitly identified.

Results: The Pain, Agitation/Sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) panel issued 37 recommendations (three strong and 34 conditional), two good practice statements, and 32 ungraded, nonactionable statements. Three questions from the patient-centered prioritized question list remained without recommendation.

Conclusions: We found substantial agreement among a large, interdisciplinary cohort of international experts regarding evidence supporting recommendations, and the remaining literature gaps in the assessment, prevention, and treatment of Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) in critically ill adults. Highlighting this evidence and the research needs will improve Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) management and provide the foundation for improved outcomes and science in this vulnerable population.

An ongoing outbreak of lung injury associated with e-cigarettes or vaping (also known as E-VALI or VALI) started in March 2019, in the USA. The cause, diagnosis, treatment, and course of this disease remains unknown.

Brief description of media:

A substantial number of patients admitted to the ICU because of an acute illness, complicated surgery, severe trauma, or burn injury will develop a de novo form of muscle weakness during the ICU stay that is referred to as “intensive care unit acquired weakness” (ICUAW). This ICUAW evoked by critical illness can be due to axonal neuropathy, primary myopathy, or both. Underlying pathophysiological mechanisms comprise microvascular, electrical, metabolic, and bioenergetic alterations, interacting in a complex way and culminating in loss of muscle strength and/or muscle atrophy.

ICUAW is typically symmetrical and affects predominantly proximal limb muscles and respiratory muscles, whereas facial and ocular muscles are often spared. The main risk factors for ICUAW include high severity of illness upon admission, sepsis, multiple organ failure, prolonged immobilization, and hyperglycemia, and also older patients have a higher risk. The role of corticosteroids and neuromuscular blocking agents remains unclear. ICUAW is diagnosed in awake and cooperative patients by bedside manual testing of muscle strength and the severity is scored by the Medical Research Council sum score. In cases of atypical clinical presentation or evolution, additional electrophysiological testing may be required for differential diagnosis.

The cornerstones of prevention are aggressive treatment of sepsis, early mobilization, preventing hyperglycemia with insulin, and avoiding the use parenteral nutrition during the first week of critical illness. Weak patients clearly have worse acute outcomes and consume more healthcare resources. Recovery usually occurs within weeks or months, although it may be incomplete with weakness persisting up to 2 years after ICU discharge. Prognosis appears compromised when the cause of ICUAW involves critical illness polyneuropathy, whereas isolated critical illness myopathy may have a better prognosis. In addition, ICUAW has shown to contribute to the risk of 1-year mortality. Future research should focus on new preventive and/or therapeutic strategies for this detrimental complication of critical illness and on clarifying how ICUAW contributes to poor longer-term prognosis.
