EM Cases emergency medicine education podcast
In this CritCases blog - a collaboration between STARS Air Ambulance Service, Mike Betzner and EM Cases, Dr. James Brokenshire presents a case of acute unstable Uterine Inversion and discusses key therapeutic maneuvers including the Johnson Maneuver, tocolytics and resuscitation of postpartum hemorrhage.
Congenital Heart Disease Emergencies on EM cases with Gary Joubert and Ashley Strobel. You might be surprised to learn that the prevalence of critical cardiac disease in infants is almost as high as the prevalence of infant sepsis. And if you’re like me, you don’t feel quite as confident managing sick infants with critical heart disease as you do managing sepsis. Critical congenital heart defects are often missed in the ED. For a variety of reasons, there are currently more children with congenital heart disease presenting to the ED than ever before and these numbers will continue to grow in the future. When I was in medical school I vaguely remember learning the complex physiology and long lists of congenital heart diseases, which I’ve now all but forgotten. What we really need to know about congenital heart disease emergencies is what actions to take in the ED when we have a cyanotic or shocky baby in front of us in the resuscitation room. So with the goal of learning a practical approach to congenital heart disease emergencies using the child’s age, colour and few simple tests, Dr. Strobel and Dr. Joubert will discuss some key actions, pearls and pitfalls so that the next time you’re faced with that crashing baby in the resuscitation room, you’ll know exactly what to do.
Journal Jam 7 - Amiodarone vs Lidocaine vs Placebo in Cardiac Arrest: The ALPS Trial. In our most popular EM Cases episode to date - ACLS Guidelines Cardiac Arrest Controversies, we boldly stated, that there has never been an antiarrhythmic medication that has shown any long term survival benefit in cardiac arrest. The use of medications in cardiac arrest has been one of those things that we all do, but that we know the evidence isn’t great for. Yet Amiodarone is still in the newest AHA adult cardiac arrest algorithm for ventricular fibrillation or pulseless ventricular tachycarida – 300mg IV after the 3rd shock with the option to give it again at 150mg after that. Anti-arrhythmics have been shown in previous RCTs to increase the rate of return of spontaneous circulation and even increased survival to hospital admission, however none of them have been able to show a decrease in mortality or a favourable neurological outcome at hospital discharge. In other words, there has never been shown a long term survival or functional benefit - which is a bit disconcerting. But now, we have a recent large randomized, controlled trial that shines some new light on the role of anti-arrythmics in cardiac arrest - The ALPS trial: Amiodarone vs Lidocaine vs placebo in out of hospital cardiac arrest. In this Journal Jam podcast, Justin Morgenstern and Anton Helman interview two authors of the ALPS trial, Dr. Laurie Morrison a world-renowned researcher in cardiac arrest and Dr. Paul Dorian, a cardiac electrophysiologist and one of Canada's leading authorities on arrhythmias about what we should take away from the ALPS trial. It turns out, it's not so simple. We also discuss the value of dual shock therapy for shock resistant ventricular fibrillation and the future of cardiac arrest care.
In anticipation of EM Cases' upcoming episode, Congenital Heart Disease Emergencies we have Dr. Gary Joubert a double certified Pediatric EM and Pediatric Cardiology expert telling his Best Case Ever of a four month old infant who presents with intermittent cyanosis. The Cyanotic Infant can present a significant challenge to the EM provider as the differential is wide, ranging from benign causes such as GERD to life threatening heart disease that may present atypically in a well-appearing child. Dr. Joubert gives us some simple sweet clinical pearls to help us along the way...
EM Cases Episode 83 - 5 Critical Care Controversies from SMACC Dublin: I had the great opportunity to gather some of the brightest minds in Emergency Medicine and Critical Care from around the world (Mark Forrest from U.K., Chris Nickson from Australia, Chris Hicks from Canada and Scott Weingart from U.S.) at the SMACC Dublin Conference and ask them about 5 Critical Care Controversies and concepts: How to best prepare your team for a resuscitation Optimum fluid management in sepsis Direct vs. video laryngoscopy as first line tool for endotracheal intubation Early vs. late trauma intubation Whether or not to attempt a thoracotomy in non-trauma centres The discussion that ensued was enlightening...
EM Cases Best Case Ever - Chris Nickson on Hickam's Dictum. Usually we use the heuristic of Occam's razor to help us arrive at one diagnosis that makes sense of all the data points that a particular patient presents to us. However sometimes it's not so straight forward and we need to think about multiple diagnoses that explain a patient's condition - Hickam's Dictum. Dr. Chris Nickson, the brains behind the Life in the Fast Lane blog tells his Best Case Ever from the SMACC Conference in Dublin, in which a patient thrombolysed for massive pulmonary embolism suffers a cardiac arrest, and the thought process he went through to discover the surprising complicating diagnoses that ensue...
EM Cases Episode 82 Emergency Radiology Controversies, pearls and pitfalls: Which patients with chest pain suspected of ACS require a CXR? What CXR findings do ED docs tend to miss? How should we workup solitary pulmonary nodules found on CXR or CT? Is the abdominal x-ray dead or are there still indications for it's use? Which x-ray views are preferred for detecting pneumoperitoneum? When should we consider ultrasound as a screening test instead of, or before, CT? What are the indications for contrast in abdominal and head CT? How should we manage the patient who has had a previous CT contrast reaction who really needs a CT with contrast? What is the truth about CT radiation for shared decision making? And much more...
This is EM Cases Journal Jam Podcast 6 - Outpatient Topical Anesthetics for Corneal Abrasions. I’ve been told countless times by ophthalmologists and other colleagues NEVER to prescribe topical anesthetics for corneal abrasion patients, with the reason being largely theoretical - that tetracaine and the like will inhibit re-epithelialization and therefore delay epithelial healing as well as decrease corneal sensation, resulting in corneal ulcers. With prolonged use of outpatient topical anesthetics for corneal abrasions, corneal opacification could develop leading to decreased vision. Now this might be true for the tetracaine abuser who pours the stuff in their eye for weeks on end, but when we look at the literature for toxic effects of using topical anesthetics in the short term, there is no evidence for any clinically important detrimental outcomes. Should we ignore the dogma and use tetracaine anyway? Is there evidence that the use of topical anesthetics after corneal abrasions is safe and effective for pain control without adverse effects or delayed epithelial healing? To discuss the paper "The Safety of Topical Anesthetics in the Treatment of Corneal Abrasions: A Review" by Drs. Swaminathan, Otterness, Milne and Rezaie published in the Journal of Emergency Medicine in 2015, we have EM Cases’ Justin Morgenstern, a Toronto-based EM Doc, EBM enthusiast as well as the brains behind the First10EM blog and Salim Rezaie, Clinical Assistant Professor of EM and Internal Medicine at University of Texas Health Science Center at San Antonio as well as the Creator & Founder of the R.E.B.E.L. EM blog and REBELCast podcast. In this Journal Jam podcast, Dr. Morgenstern and Dr. Rezaie also discuss a simple approach to critically appraising a systematic review article, how to handle consultants who might not be aware of the literature and/or give you a hard time about your decisions and much more...
Traditionally we've run at least 2 troponins 6 or 8 hours apart to help rule out MI and recently in algorithms like the HEART score we've combined clinical data with a 2 or 3 hour delta troponin to help rule out MI. The paper we'll be discussing here is a multicentre/multinantional study from the Canadian Medical Association Journal from this year out of Switzerland entitled "Prospective validation of a 1 hour algorithm to rule out and rule in acute myocardial infarction using a high sensitivity cardian troponin T assay" with lead author Tobias Reichlin. It not only looks at whether or not we can rule out MI using a delta troponin at only 1 hour but whether or not we can expedite the ruling in of MI using this protocol.
Pediatric seizures are common. So common that about 5% of all children will have a seizure by the time they’re 16 years old. If any of you have been parents of a child who suddenly starts seizing, you’ll know intimately how terrifying it can be. While most of the kids who present to the ED with a seizure will end up being diagnosed with a benign simple febrile seizure, some kids will suffer from complex febrile seizures, requiring some more thought, work-up and management, while others will have afebrile seizures which are a whole other kettle of fish. We need to know how to differentiate these entities, how to work-them up and how to manage them in the ED. At the other end of the spectrum of disease there is status epilepticus – a true emergency with a scary mortality rate - where you need to act fast and know your algorithms like the back of your hand. This topic was chosen based on a nation-wide needs assessment study conducted by TREKK (Translating Emergency Knowledge for Kids), a collaborator with EM Cases. With the help of two of Canada’s Pediatric Emergency Medicine seizure experts hand picked by TREKK, Dr. Lawrence Richer and Dr. Angelo Mikrogianakis, we’ll give you the all the tools you need to approach the child who presents to the ED with seizure with the utmost confidence.
