BCE 73 Esmolol in Refractory Ventricular Fibrillation

In anticipation of EM Cases Episode 112 on Tachydysrhthmias with Amal Mattu and Paul Dorion, Melanie Baimel tells her Best Case Ever of a previously healthy young man who presents in refractory ventricular fibrillation after receiving multiple single shocks, ongoing chest compressions, several rounds of epinephrine, amiodarone and dual sequence defibrillation without ROSC...

Episode 86 – Emergency Management of Hyperkalemia

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...

Best Case Ever 49 – Post-Arrest Hyperkalemia

Melanie Baimel's Best Case Ever on Post-Arrest Hyperkalemia on EM Cases. Post arrest patients can sometimes be challenging. We need to think of a variety of underlying causes of the arrest, antiarrhythmics, possible cath lab activation, targeted temperature management, sedation and more. To add to this, many post arrest patients do not have ideal vital signs that require attention. In this Best Case Ever, in anticipation of our upcoming episode on A Rational Approach to Hyperkalemia Dr. Melanie Baimel describes a post arrest patient who remains bradycardic and hypotensive despite multiple pressors....

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...

Best Case Ever 33: Over-correction of Hyponatremia

Rapid over-correction of Hyponatremia can have devastating consequences: for one, osmotic demyelination syndrome (ODS) can result in destruction of the pons and a locked-in state. We don't see ODS very much as it's onset is delayed and usually sets in after the patient is admitted to hospital (or worse, sent home). Nonetheless, we need to know how to manage Hyponatremia in the ED so that we prevent ODS from ever happening. In this Best Case Ever, Dr. Melanie Baimel describes the case of a young woman who came in to the ED after drinking alcohol and taking Ecstasy, wanted to leave AMA after her Hyponatremia had inadvertently been corrected too rapidly, and the conundrum that ensues. In the upcoming episode, Dr. Baimel and the first ever Internal Medicine specialist on EM Cases, Dr. Ed Etchels, discuss a rational step-wise approach to managing Hyponatremia, tailored for the EM practitioner; when you might consider giving DDAVP in the ED, the best way to correct Hyponatremia, how to manage the patient who's Hyponatremia has been corrected too quickly, and an easy approach to the differential diagnosis. Get a sneak peak at the algorithm that will be explained and reviewed in the upcoming episode...... [wpfilebase tag=file id=577 tpl=emc-play /] [wpfilebase tag=file id=578 tpl=emc-mp3 /]
