BACKGROUND: Extracorporeal cardiopulmonaryresuscitation (ECPR) is emerging as a viable rescue strategy for refractory out-of-hospital cardiac arrest. In the U.S., limited training of emergency medicine providers is a barrier to widespread implementation. AIMS: Test the hypothesis that emergency medicine physicians and nurses can acquire and retain the skills to rapidly and safely initiate ECPR using high-fidelity simulation. STUDY DESIGN: Prospective interventional study...

BACKGROUND: The "two-bag method" of management of diabetic ketoacidosis (DKA) allows for titration of dextrose delivery by adjusting the infusions of two i.v. fluid bags of varying dextrose concentrations while keeping fluid, electrolyte, and insulin infusion rates constant. OBJECTIVE: We aimed to evaluate the feasibility and potential benefits of this strategy in adult emergency department (ED) patients with DKA. METHODS: This is a before-and-after comparison of a protocol using the two-bag method operationalized in our adult ED in 2015...

Critical care fellowship training in the United States differs based on specific specialty and includes medicine, surgery, anesthesiology, pediatrics, emergency medicine, and neurocritical care training pathways. We provide an update regarding the number and growth of US critical care fellowship training programs, on-duty residents and certified diplomates, and review the different critical care physician training pathways available to residents interested in pursuing a fellowship in critical care. Data were obtained from the Accreditation Council for Graduate Medical Education and specialty boards (American Board of Internal Medicine, American Board of Surgery, American Board of Anesthesiology, American Board of Pediatrics American Board of Emergency Medicine) and the United Council for Neurologic Subspecialties for the last 16 years (2001-2017)...

PURPOSE: To characterize the current scope and practices of centers performing extracorporeal cardiopulmonary resuscitation (eCPR) on the undifferentiated patient with cardiac arrest in the emergency department. METHODS: We contacted all US centers in January 2016 that had submitted adult eCPR cases to the Extracorporeal Life Support Organization (ELSO) registry and surveyed them, querying for programs that had performed eCPR in the Emergency Department (ED ECMO)...

Herpes zoster, commonly called shingles, is a disease that results from the reactivation of varicella zoster virus. Local trauma has been reported as a precipitant for reactivation, but this condition is rarely seen localized to a fresh surgical incision. We present the case of a patient who developed shingles overlying the incision site of a recently buried central venous access port, illustrating the need to consider this diagnosis as a unique imposter of localized infection or reaction at sites of recent procedural trauma...

BACKGROUND: Acute kidney injury (AKI) is an important complication in surgical patients. Existing biomarkers and clinical prediction models underestimate the risk for developing AKI. We recently reported data from two trials of 728 and 408 critically ill adult patients in whom urinary TIMP2•IGFBP7 (NephroCheck, Astute Medical) was used to identify patients at risk of developing AKI. Here we report a preplanned analysis of surgical patients from both trials to assess whether urinary tissue inhibitor of metalloproteinase 2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7) accurately identify surgical patients at risk of developing AKI...

Extracorporeal membrane oxygenation (ECMO) is a mode of extracorporeal life support that augments oxygenation, ventilation and/or cardiac output via cannulae connected to a circuit that pumps blood through an oxygenator and back into the patient. ECMO has been used for decades to support cardiopulmonary disease refractory to conventional therapy. While not robust, there are promising data for the use of ECMO in acute hypoxemic respiratory failure, cardiac arrest, and cardiogenic shock and the potential indications for ECMO continue to increase...

The authors aimed to evaluate age-related differences in inflammation biomarkers during the first 72 h of hospitalization for sepsis. This was a secondary analysis of a prospective observational cohort of adult patients (n = 855) from 10 urban academic emergency departments with confirmed infection and two or more systemic inflammatory response syndrome criteria. Six inflammation-related biomarkers were analyzed-chemokine (CC-motif) ligand-23, C-reactive protein, interleukin-1 receptor antagonist, neutrophil gelatinase-associated lipocalin (NGAL), peptidoglycan recognition protein, and tumor necrosis factor receptor-1a (TNFR-1a)-measured at presentation and 3, 6, 12, 24, 48, or 72 h later...

RATIONALE: We recently reported two novel biomarkers for acute kidney injury (AKI), tissue inhibitor of metalloproteinases (TIMP)-2 and insulin-like growth factor binding protein 7 (IGFBP7), both related to G1 cell cycle arrest. OBJECTIVES: We now validate a clinical test for urinary [TIMP-2]·[IGFBP7] at a high-sensitivity cutoff greater than 0.3 for AKI risk stratification in a diverse population of critically ill patients. METHODS: We conducted a prospective multicenter study of 420 critically ill patients...

INTRODUCTION: Acute kidney injury (AKI) can evolve quickly and clinical measures of function often fail to detect AKI at a time when interventions are likely to provide benefit. Identifying early markers of kidney damage has been difficult due to the complex nature of human AKI, in which multiple etiologies exist. The objective of this study was to identify and validate novel biomarkers of AKI. METHODS: We performed two multicenter observational studies in critically ill patients at risk for AKI - discovery and validation...

OBJECTIVES: Myocardial dysfunction is an important aspect of sepsis pathophysiology. B-type natriuretic peptide (BNP) is a neurohormone released from the ventricles in response to myocardial stretch and volume overload. The authors hypothesized that an elevated BNP in patients presenting to the emergency department (ED) with suspected sepsis are at increased risk for development of adverse events. METHODS: This was a prospective, observational, multicenter cohort study in 10 EDs...

The CardioWest temporary total artificial heart serves as a viable bridge to orthotopic heart transplantation in patients who are experiencing end-stage refractory biventricular heart failure. This device is associated with a low, albeit still substantial, risk of thrombosis. Platelet interactions with artificial surfaces are complex and result in continuous activation of contact proteins despite therapeutic anticoagulation. We searched the medical literature (publication dates, January 1962-October 2009) in order to evaluate means of mitigating adverse events that have occurred after implantation of the CardioWest temporary total artificial heart...

OBJECTIVES: Critical care medicine (CCM) is of growing interest among emergency physicians (EPs), but the number of CCM-trained EPs and their postfellowship practice is unknown. This study's purpose was to conduct a descriptive census survey of EPs who have completed or are currently in a CCM fellowship. METHODS: The authors created a Web-based survey, and requests to participate were sent to EPs who have completed or are currently in a CCM fellowship. Responses were collected over a 12-month period...

STUDY OBJECTIVE: We assess the diagnostic accuracy of plasma neutrophil gelatinase-associated lipocalin (NGAL) to predict acute kidney injury in emergency department (ED) patients with suspected sepsis. METHODS: We conducted a secondary analysis of a prospective observational study of a convenience sample of patients from 10 academic medical center EDs. Inclusion criteria were adult patients aged 18 years or older, with suspected infection or a serum lactate level greater than 2...

PURPOSE: Abnormalities of strong ion gap (SIG) are common in critically ill intensive care unit (ICU) patients in conjunction with a high incidence of acid-base abnormalities. However, it is unknown whether abnormalities in SIG are also seen in ICU patients without active acid-base abnormalities. Thus, we conducted this pilot study to examine differences in quantitative acid-base variables between healthy adult volunteers and stable ICU patients with no suspected acid-base abnormalities...
