In response to concerns about patient care and safety, our urban, tertiary care, Level 1 trauma center adult emergency department (ED) created an advanced practice provider-staffed critical care step-down unit (CCSU). We conducted a comprehensive evaluation of the CCSU's impact on patient care, safety, and ED operations.
 
  We compared ED length of stay, return visits to the ED within 72 hours, billing code assignments (current procedural terminology evaluation and management [CPT E&M] codes), and quality of electronic health record documentation per QNOTE for the 2 years after the CCSU was initiated (CCSU period) versus before its initiation (pre-CCSU period).
 
  There were 31,418 critical care ED patient visits in the pre-CCSU period and 33,396 in the CCSU period. Median ED length of stay did not change overall between the CCSU versus pre-CCSU period (∆1 [95% confidence interval (CI) = -2.4, 4.4] minutes), but decreased for patients who remained in the critical care suites (∆-4 [95% CI = -7.8, -0.2] minin critical care in ED.
  We sought to evaluate the influence of several well-documented, readily available risk factors that may influence a psychiatric consultant's decision to admit an emergency department (ED) patient reporting suicidal ideation for psychiatric hospitalization.
 
  We conducted a retrospective study of adult patients presenting to six affiliated EDs within Pennsylvania from January 2015 to June 2017. We identified 533 patients reporting current active suicidal ideation and receiving a complete psychiatric consultation. Socio-demographic characteristics, psychiatric presentation and history, and disposition were collected. Decision tree analysis was conducted with disposition as the outcome.
 
  Four of 27 variables emerged as most influential to decisionmaking, including psychiatric consultant determination of current suicide risk, patient age, current depressive disorder diagnosis, and patient history of physical violence. Likelihood of admission versus discharge ranged from 97% to 58%, depending on the variables cons made. Patient suicide risk, determined by considering empirically supported risk factors for suicide attempt and death, contributes the greatest influence on a psychiatric consultant's decision to admit. In line with American College of Emergency Physicians (ACEP) recommendations, this study accentuates the importance of using clinical judgment and adjunct measures to determine patient disposition within this population.Anaphylactic shock to contrast media can progress to cardiac arrest despite appropriate treatment. During anaphylactic shock to contrast media, rapid vasodilation and a massive fluid shift can occur. Here we report a patient who developed cardiac arrest induced by anaphylactic shock to iodinated contrast medium and exhibited rapid collapse of the inferior vena cava (IVC) on enhanced abdominal computed tomography (CT) images. The patient underwent postsurgical unenhanced and contrast-enhanced abdominal CT follow-up of cecum cancer. She had neither allergy nor medical history except for the cancer. She did not complain of any symptoms immediately after completion of the CT. However, she developed anaphylactic shock and pulseless electrical activity cardiac arrest only 2 minutes after finishing the CT despite appropriate treatment. Emergency physicians successfully treated the patient using advanced life support and targeted temperature management. She recovered with good overall and cerebral performance (Overall Performance Category (OPC) 1 and Cerebral Performance Category (CPC) 1). On the contrast-enhanced CT images, she exhibited rapid collapse of the IVC, although it was normal on the unenhanced CT images. The collapsed IVC is a good indicator of hypovolemia in patients with trauma. In this case, we considered that rapid vasodilation and a massive volume shift might have caused the collapsed IVC. This finding suggests the importance of aggressive volume resuscitation as well as epinephrine injection in patients with anaphylactic shock to contrast media. Furthermore, this finding occurred before the onset of clinical symptoms, and there is a possibility that it could be used as an indicator of anaphylactic shock to contrast media.Arrhythmogenic right ventricular cardiomyopathy is a cause of sudden cardiac death in often otherwise healthy young adults.  https://www.selleckchem.com/products/tacrine-hcl.html  Cardiac arrest following an unstable tachydysrhythmia may be the primary presenting symptom. Venous arterial extracorporeal life support via extracorporeal membrane oxygenation (VA ECMO) has been used as a rescue strategy in emergency departments (EDs) for patients with cardiac arrest unresponsive to conventional cardiopulmonary resuscitation. We present a case of a previously healthy 18-year-old male who presented to our emergency department with ECG features of arrhythmogenic right ventricular cardiomyopathy and subsequent pulseless polymorphic ventricular tachycardia refractory cardiac arrest, treated with ED-initiated VA ECMO.With an increasing number of left ventricular assist devices (LVADs) being placed every year, emergency clinicians are increasingly likely to encounter them in their practice. Patients may present to the emergency department (ED) with significant hemodynamic perturbations with an LVAD and it is imperative that emergency clinicians are able to assess and treat conditions contributing to low cardiac output states. This review describes the important aspects of the third generation of LVADs and their complications as well as common management approaches for the emergency physician.
  In this systematic review and meta-analysis of propensity score-matched cohort studies, we quantitatively summarize whether venoarterial extracorporeal membrane oxygenation (VA-ECMO) used as extracorporeal cardiopulmonary resuscitation (ECPR), compared with conventional cardiopulmonary resuscitation (CCPR), is associated with improved rates of 30-day and long-term favorable neurological outcomes and survival in patients resuscitated from in- and out-of-hospital cardiac arrest.
 
  We searched MEDLINE via PubMed, Embase, Scopus, and Google Scholar for eligible studies on January 14, 2019. All searches were limited to studies published between January 2000 and January 2019. Two investigators independently evaluated the quality (or certainty) of evidence according to GRADE guidelines. Pooled results are presented as relative risks (RRs) with 95% confidence intervals (CIs).
 
  Six cohort studies using propensity score-matched analysis were included, totaling 1108 matched patients. Pooled analyses showed that ECPR was likely associated with improved 30-day and long-term favorable neurological outcome in adults compared to CCPR for in- and out-of-hospital cardiac arrest (RR = 2.
