Emergency Medicine Cases

Alcohol withdrawal is everywhere. We see over half a million patients in U.S. EDs for alcohol withdrawal every year. Despite these huge volumes of patients and the diagnosis of alcohol withdrawal seeming relatively straightforward, it’s actually missed more often than we’d like to admit, being confused with things like drug intoxication or sepsis. Or it’s not even on our radar when an older patient presents with delirium. What’s even more surprising is that even if we do nail the diagnosis, observational studies show that in general, alcohol withdrawal is poorly treated. So, to help you become masters of alcohol withdrawal management, our guest experts on this podcast are Dr. Bjug Borgundvaag, an ED doc and researcher with a special interest in emergency alcohol related illness and the director of Schwartz-Reismann Emergency Medicine Institute, Dr. Mel Kahan, an addictions specialist for more than 20 years who’s written hundreds of papers and books on alcohol related illness, and the medical director of the substance use service at Women’s College Hospital in Toronto, and Dr. Sara Gray, ED-intensivist at St. Michael's Hospital...

In anticipation of EM Cases Episode 87 on Alcohol Withdrawal Dr. Sara Gray describes her Best Case Ever of severe alcohol withdrawal and Delirium Tremens from Janus General. Also on this podcast Dr. Anand Swaminathan reacts to Episode 86 Emergency Management of Hyperkalemia and discusses the use of calcium in the setting of digoxin toxicity. Early recognition and treatment of Delirium Tremens - a rapid onset of severe alcohol withdrawal accompanied by delirium and autonomic instability about 3-10 days after the appearance of withdrawal symptoms - is key to preventing long term morbidity and mortality...

This is 'A Nuanced Approach to Emergency Management of Hyperkalemia' on EM Cases. Of all the electrolyte emergencies, hyperkalemia is the one that has the greatest potential to lead to cardiac arrest. And so, early in my EM training I learned to get the patient on a monitor, ensure IV access, order up an ECG, bombard the patient with a cocktail of kayexalate, calcium, insulin, B-agonists, bicarb, fluids and furosemide, and get the patient admitted, maybe with some dialysis to boot. Little did I know that some of these therapies were based on theory alone while others were based on a few small poorly done studies. It turns out that some of these therapies may cause more harm than good, and that precisely when and how to give these therapies to optimize patient outcomes is still not really known...

This podcast discusses a best case scenario involving a post-arrest patient with hyperkalemia. It highlights the challenges in managing post-arrest patients and the various factors to consider. The importance of addressing vital signs and potential causes of the arrest is emphasized.

Psychiatric chief complaints comprise about 6 or 7% of all ED visits, with the numbers of psychiatric patients we see increasing every year. The ED serves as both the lifeline and the gateway to psychiatric care for millions of patients suffering from acute behavioural or psychiatric emergencies. As ED docs, besides assessing the risk of suicide and homicide, one of the most important jobs we have is to determine whether the patient’s psychiatric or behavioral emergency is the result of an organic disease process, as opposed to a psychological one. There is no standard process for this. With the main objective in mind of picking up and appropriately managing organic disease while improving flow, decreasing cost and maintaining good relationships with our psychiatry colleagues, we have Dr. Howard Ovens, Dr. Brian Steinhart and Dr. Ian Dawe discuss this controversial topic...

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...
