Can arginine supplements improve the hemodynamics of children with severe pain or acute chest syndrome (ACS) related to sickle cell anemia? Although mortality rates in children with sickle cell disease (SCD) have improved over the past decade, ACS and vasoocclusive episodes (VOE) remain relatively common diagnoses in pediatric ICUs. This Concise Critical Appraisal explores an article in which Onalo et al completed the second phase of their work determining the role that L-arginine treatment may play in the cardiopulmonary status of children with SCD and VOE, with or without ACS. In the first phase of their work, the authors demonstrated decreased hospitalization time, decreased opioid use, and the absence of serious adverse events in children with SCD after receiving L-arginine therapy.
The COVID-19 pandemic created a new challenging environment in which healthcare workers must survive. Before the pandemic, healthcare workers experienced burnout due to resource allocation and shortages, mental anguish, and long work hours. The pandemic further exacerbated this situation, creating a new crisis within our already frayed healthcare system. This Concise Critical Appraisal dives into an article published in Critical Care Medicine that reviewed the causes of burnout and the correlation between the COVID-19 pandemic and workplace burnout.
Has the rate of venous thromboembolism (VTE) in children changed over time? A 2009 study reported a 70% increase in VTE in acutely and chronically ill children. The reasons for this increase were not clear but were postulated to be related to improved survival of critically ill children, increased use of central venous catheters, and increased prevalence of adolescent obesity. This Concise Critical Appraisal dives into a 2022 article that sought to determine whether the rate of VTE continued to increase between 2008 and 2019.

Tracheal intubation is a high-risk procedure that is frequently performed in the emergency department and intensive care unit. Failure of first-pass success (FPS) when intubating has been shown to be associated with major adverse events, so maximizing FPS is paramount for improving patient outcomes. This Concise Critical Appraisal explores a study published in JAMA that sought to determine the effect of using a bougie (tracheal tube introducer) versus an endotracheal tube with stylet when intubating.
Although several trials have examined in-hospital cardiac arrest (IHCA), only two trials in the past decade have examined the use of vasopressin and glucocorticoids for IHCA. Both trials found improved survival and favorable neurologic outcome with a vasopressin-epinephrine-methylprednisolone combination. Because of a lack of additional supporting evidence, neither the American nor European international guidelines have recommended this combination for IHCA. This Concise Critical Appraisal examines an article by Andersen et al that attempted to validate the results of these trials.
This Concise Critical Appraisal explores an article published in Critical Care Medicine on a program at Cooper University Hospital in Camden, New Jersey, USA, that implemented a previously published successful ECMO model, in which ECMO cannulation primarily performed by cardiothoracic surgeons is transitioned to medical intensivist-led cannulation. This article is significant in advancing the role of the medical intensivist in the cannulation of patients who require ECMO.
The average annual incidence of pediatric in-hospital cardiac arrest (IHCA) has recently been estimated at more than 15,000 cases.1 Survival rates for pediatric patients who have had pulseless cardiac arrest have remained below 50% for the past decade.2,3 The American Heart Association currently recommends epinephrine, the cornerstone medication for cardiac arrest, dosed every 3 to 5 minutes in adult and pediatric cardiac arrest, although there is conflicting evidence about whether this is the best interval.4,5 Epinephrine is believed to acutely increase coronary perfusion pressure by increasing diastolic blood pressure (DBP).
This Concise Critical Appraisal explores an article in The Lancet Respiratory Medicine that evaluated the efficacy of awake prone positioning to prevent intubation or death in patients with severe COVID-19. This meta-trial used a new study design that allowed for the combination of six simultaneous national randomized, controlled, open-label trials.
Clostrididioides difficile infection (CDI) occurs in about 4% of ICU patients, causing fulminant colitis and death in nearly 60% of symptomatic critically ill patients, so it is imperative for ICU professionals to stay abreast of the evidence-based advancements of CDI management. In June 2021, the Infectious Diseases Society of America and Society for Healthcare Epidemiology of America updated their recommendations on the management of CDI in adults. This Concise Critical Appraisal offers a review of the updated guidelines.
