Deep vein thrombosis (DVT) is always a consideration when patients with asymmetric lower extremity swelling. Why is one leg. Two-point focused DVT ultrasonography of the femoral and popliteal veins can be incredibly useful in the Emergency Department when trying to narrow the differential diagnosis. Drs. Margaret Greenwood-Ericksen, Joshua Rempell, and Mike Stone provide a clear, image-based clinical reference tool on this ultrasound technique.
So many great information can be gleaned from a focused echocardiogram in Emergency Department patients. What views are you obtaining? What is the importance of the e-point septal separation (EPSS) and how to measure this? Drs. Jimmy Fair, Mike Mallon, and Mike Stone provide a terrific step-by-step image-based guide to these questions that you can use at the bedside as a refresher.
When the topic of pericarditis is mentioned, the classic electrocardiogram (ECG) findings of diffuse ST elevation and PR depression are often the focus of discussion. What about the criteria for diagnosis, the 3-prong approach to treatment, and contraindications to colchicine? These are the great questions answered by Dr. Chris Bond (@socmobem) in this PV card, which summarize 3 key papers by Imazio et al from the New England Journal of Medicine, Archives of Internal Medicine, and Circulation.
Welcome to another ultrasound-based case, part of the “Ultrasound For The Win!” (#US4TW) Case Series. In this peer-reviewed case series, we focus on a real clinical case where bedside ultrasound changed the management or aided in the diagnosis. In this case, a 39-year-old female with history of lupus presents with chest pain.
Welcome to another ultrasound-based case, part of the “Ultrasound For The Win!” (#US4TW) Case Series. In this peer-reviewed case series, we focus on real clinical cases where bedside ultrasound changed management or aided in diagnoses. In today’s case, a 74-year-old woman presents to the Emergency Department with painful right arm paresthesias.
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.
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.
