Esmolol Use in Cardiac Arrest

ESM-lg

There is an abundance of sympathetic stimulation in patients who present in ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) whether endogenously released as a stress response or exogenously administered in a resuscitation attempt.1 The hope is that sympathetic stimulation will increase the coronary and cerebral perfusion pressure of the patient and aid in resuscitation. However, there are numerous detrimental effects associated with epinephrine such as an increase in myocardial oxygen demand leading to increased ischemia.2

Contrary to traditional teaching, interesting evidence exists in both animal models as well as in limited reports in human subjects that show a potential benefit with beta blockade in cardiac arrest.

AIR Series: Peripheral Vascular Disease Module 2014

Welcome to the fourth ALiEM Approved Instructional Resources (AIR) Module! In an effort to reward our residents for the reading and learning they are already doing online, we have created an Individual Interactive Instruction (III) opportunity utilizing FOAM resources for U.S. Emergency Medicine residents. For each module, the AIR board curates and scores a list of blogs and podcasts. A quiz is available to complete after each module to obtain residency conference credit. Once completed, your name and institution will be logged into our private database, which participating residency program directors can access to provide proof of completion.

PV Card: Focused Abdominal Aorta Ultrasound

UltrasoundIn this next ultrasound installment in the PV Card series, Drs. Victoria Koskenoja, Heidi Kimberly, and Mike Stone succinctly summarize the focused abdominal aorta ultrasound to assess for an abdominal aortic aneurysm (AAA). These can serve as key reference cards when you do your next AAA scan. Don’t miss the last card with tips on optimizing the view and common pitfalls.

Beta Blockers vs Calcium Channel Blockers for Atrial Fibrillation Rate Control: Thinking Beyond the ED

AFibIntravenous beta blockers and non-dihydropyridine calcium channel blockers are recommended first-line for atrial fibrillation (AF) with rapid ventricular rate (RVR) [1]. In a previous post, Bryan Hayes (@PharmERToxGuy) provided an overview of the data comparing beta blockers to calcium channel blockers for atrial fibrillation rate control in the ED. Here is part 2 of our two-part AF series.   (more…)

Diagnose on Sight: Swollen Upper Extremity in a Patient with End Stage Renal Disease

AV fistula pseudoaneurysmCase: A 45 year old female with end-stage renal disease presents with 2 days of worsening pain, swelling, and color change of her left upper extremity.  The symptoms began after her left arm arteriovenous (AV) fistula was accessed for hemodialysis. The skin is tense and a bruit is present. What is your diagnosis for this swollen upper extremity? Click on the image for a larger view.

ADJUST-PE Study: ALiEM-Annals of EM Journal Club

ALiEM-AnnalsEM-SquareWe are very excited this month to bring you our fourth ALiEM-Annals of EM Global Journal Club on the use of age-adjusted D-dimer levels to help exclude the diagnosis of pulmonary embolism (PE). We hope you will participate in an online discussion of the four posted questions below from now until August 29th. Respond by commenting below or tweeting (#ALiEMJC). Mark your calendars: On Thursday, August 28th at 16:30 CST (17:30 EST), we will be hosting a 30-minute live Google Hangout with Drs. Jeff Kline and Jonathan Kirschner, the authors of the Annals of Emergency Medicine Journal Club for the ADJUST-PE Trial, that is informed by the discussion. Later this year, a summary of this journal club will hopefully be published in Annals of EM.

Atrial Fibrillation Rate Control in the ED: Calcium Channel Blockers or Beta Blockers?

Screen Shot 2014-05-27 at 2.26.48 AMRate control with IV medications is recommended for atrial fibrillation in the acute setting in patients without preexcitation. This was a Class 1 recommendation (Level of Evidence B) per the 2014 AHA/ACC/HRS Guideline for the Management of Patients With Atrial Fibrillation [1]. What does the evidence say? Are calcium channel blockers or beta blockers better?
