Episode 60: Emergency Management of Hyponatremia
In this EM Cases episode Dr. Melanie Baimel and Dr. Ed Etchells discuss a simple and practical step-wise approach to the emergency management of hyponatremia: 1. Assess and treat neurologic emergencies related to hyponatremia with hypertonic saline 2. Defend the intravascular volume 3. Prevent further exacerbation of hyponatremia 4. Prevent rapid overcorrection 5. Ascertain a cause Dr. Etchells and Dr. Baimel answer questions such as: What are the indications for giving DDAVP in the emergency management of hyponatremia? What is a simple and practical approach to determining the cause of hyponatremia in the ED? How fast should we aim to correct hyponatremia? What is the best fluid for resuscitating the patient in shock who has a low serum sodium? Why is the management of the marathon runner with hyponatremia counter-intuitive? What strategies can we employ to minimize the risk of Osmotic Demyelination Syndrome (OSD) and cerebral edema in the emergency management of hyponatremia? and many more...
Episode 59b: Amy Plint on the Management of Bronchiolitis
In response to Episode 59 with Dr. Sanjay Mehta and Dr. Dennis Scolnik on the emergency department diagnosis and management of Bronchiolitis, Dr. Amy Plint, one of Canada's most prominent researchers in Bronchiolitis and the Chair of Pediatric Emergency Research Canada, tells her practical approach to choosing medications in the emergency department, the take home message from her landmark 2009 NEJM study on the use of nebulized epinephrine and dexamethasone for treating Bronchiolitis, and the future of Bronchiolitis research.
Episode 59: Bronchiolitis
This EM Cases episode is on the diagnosis and management of Bronchiolitis. Bronchiolitis is one of the most common diagnoses we make in both general and pediatric EDs, and like many pediatric illnesses, there’s a wide spectrum of severity of illness as well as a huge variation in practice in treating these children. Bronchiolitis rarely requires any work up yet a lot of resources are used unnecessarily. We need to know when to worry about these kids, as most of them will improve with simple interventions and can be discharged home, while a few will require complex care. Sometimes it’s difficult to predict which kids will do well and which kids won’t. Not only is it difficult to predict the course of illness in some of these children but the evidence for different treatment modalities for Bronchiolitis is all over the place, and I for one, find it very confusing. Then there’s the sphincter tightening really sick kid in severe respiratory distress who’s tiring with altered LOC. We need to be confident in managing these kids with severe disease. So, with the help of Dr. Dennis Scolnik, the clinical fellowship program director at Toronto’s only pediatric emergency department and Dr. Sanjay Mehta, an amazing educator who you might remember from his fantastic work on our Pediatric Ortho episode, we’ll sort through how to assess the child with respiratory illness, how to predict which kids might run into trouble, and what the best evidence-based management of these kids is.

Episode 58: Tendons and Ligaments – Commonly Missed Uncommon Orthopedic Injuries Part 2
In part 2 of our round-table discussion on EM Cases with sports medicine guru Dr. Ivy Cheng and orthopedic surgeon Dr. Hossein Mehdian we elucidate some key commonly missed uncommon orthopedic injuries that if mismanaged, carry significant long term morbidity. Injuries of the tendons and ligaments are often overlooked by emergency providers as relatively benign injuries and generally are not well understood. Syndesmosis Injuries typically occur in impact sports. They are missed in about 20% of cases, as x-rays findings are often subtle or absent. The mechanism, physical exam findings, such as the Hopkin's Test, and associated injuries are important to understand to help make the diagnosis and provide appropriate ED care. Distal Biceps Tendon Rupture is almost exclusively a male injury and occurs in a younger age group compared to the Proximal Biceps Rupture. It is important to distinguish these injuries as their management and outcomes are different. The mechanism and physical exam findings of Distal Biceps Tendon Rupture, such as the Hook Test, are key in this respect. Quadriceps Tendon Rupture is often misdiagnosed as a simple ‘knee sprain’, but should be consideration for surgical intervention. Quadriceps tendon ruptures are more commonly seen in patients older than 40 years and are more common than patella tendon ruptures which are more commonly seen in patients under 40 years of age. Interestingly, up to 1/3 of patients present with bilateral quadriceps tendon ruptures, so comparing to the contralateral knee may be misleading. There is a spectrum of knee extensor injuries that should be understood in order to provide proper care, with the Straight-Leg-Raise Test being abnormal in all of them. This is of the most important physical exam maneuvers to perform on every ED patient with a knee injury. The x-ray findings of these injuries may be subtle or absent, and proper immobilization of these injuries is important to prevent recoil of the tendon. Patients with calf pain and Gastrocnemius Tears are often misdiagnosed as having a DVT. In fact, one small study showed that gastrocnemius tears were misattributed to DVT in 29% of patients. This confusion occurs because sometimes patients who suffer a gastrocnemius tear report a prodrome of calf tightness several days before the injury, suggesting a potential chronic predisposition. With a good history and physical, and POCUS if you’re skilled at it, needless work-ups for DVT can be avoided.

Episode 57: The Stiell Sessions 2 – Update in Atrial Fibrillation 2014
In this bonus EM Cases podcast, The Stiell Sessions 2, we have Dr. Ian Stiell discussing an update in Atrial Fibrillation 2014 management including the age-old question of rate control vs rhythm control, the new CHADS-65 algorithm for oral anticogulant therapy, the need to initiate anticoagulant therapy in the ED, the more aggressive use of the Ottawa Aggressive Protocol, the dangers of attempting to cardiovert unstable patients who are in permanent Atrial Fibrillation, the new 150 rule to help determine the likelihood of successful cardioversion and much more. Thanks to all the listeners who did the survey on clinical decision rules and the post-listen survey.
