Beta-Blockers for Inhalant-Induced Ventricular Dysrhythmias
Background There are a few unique scenarios when beta-blockers may be indicated for patients in cardiac arrest. Use of esmolol for refractory ventricular fibrillation was summarized in a 2016 PharmERToxGuy post with an accompanying infographic. Another potential use for beta-blockers is in the rare case of a patient with inhalant-induced ventricular dysrhythmias. The term ‘sudden sniffing death’ refers to acute cardiotoxicity associated with inhaling hydrocarbons. Check out this ACMT Toxicology Visual Pearl for more information about the background and diagnosis of inhalant abuse. It is thought that inhalants causes myocardial sensitization via changes in various cardiac channels (e.g., sodium channels, [+]
SplintER Series: To Immobilize or Not to Immobilize: That is the Question

GroundED in EM: A new ALiEMU course series for third-year medical students
During the pandemic, similar to how a work-from-home mentality has become more accepted, a learn-on-own mentality has arisen for medical students. The success of the 9-part Bridge to Emergency Medicine (EM) self-guided curriculum for senior medical students interested in EM has confirmed this. This was evidenced by over 130,000 page views about the Bridge curriculum since March 2020 and 609 awarded ALiEMU certificates since April 2021 (launched only 2 months ago!). GroundED in EM: A new curriculum for third-year medical students We are thrilled to announce a 4-week, self-guided reading/listening curriculum along with choose-your-own-adventure cases paired now with ALiEMU quizzes, [+]
Are You Using the Right Evaluation Tool to Assess Learners? Putting Validity on Trial
As medical educators, we often rely on assessment tools to evaluate our learners. Whether in the form of a post-lecture survey or a checklist by a standardized patient assessment, tools are used throughout medical training and beyond. How do we know the tool we are using is appropriate? Is it assessing the right things? Do the scores have any meaning? We often search for tools that have been “validated” and feel more confident applying the results. But what makes a tool “valid”? With a few simple concepts, we can better choose and create our assessment tools and therefore better cater [+]

Diagnosis on Sight: Neck Bruising Leads to a Surprise Diagnosis
A 76-year-old female with a history of HTN, TIA, CAD, left CEA, and CKD presented to the emergency department for evaluation of neck bruising and swelling.

How I Work Smarter: Miguel Reyes, MD
One word that best describes how you work? Comfortable Current mobile device iPhone 12 Pro Computer Macbook Air What is something you are working on now? Wound Care article, REBEL EM CME content, Journal Reviews How did you come up with this Idea/Project? It was an opportunity that presented itself during the fellowship. It’s a collaborative effort with other faculty members to pull together this large review article, its a lot of work and effort but I think it’ll be worth it. As for the REBEL content, I’ve been working with Salim for a little bit and this chance came [+]
Trick of the Trade: Upsize the IV with the tourniquet infusion technique
There you are, middle of the night and EMS just brought you one of the sickest of the sick: a septic-looking, chronically ill-appearing, frail, and malnourished patient with low blood pressures. They need vascular access for fluids, antibiotics, and possibly even vasopressors. The patient arrives with only a 22-gauge peripheral IV in the hand. You ask for two large bore IVs. But unfortunately, your best nurses and techs can’t find a vein, and their initial attempts are unsuccessful. Do you move right towards ultrasound-guided placement, intraosseous needle, or a central line? What if the patient only needs a fluid bolus, [+]
