Core EM - Emergency Medicine Podcast

Delve into the urgent strategies for managing pulseless ventricular tachycardia and ventricular fibrillation. Timely defibrillation and high-quality chest compressions are crucial in cardiac arrest situations. Traditional ACLS guidelines are challenged, advocating for a more flexible approach to medication use. Discover insights on beta blockers and innovative dual defibrillation techniques that could enhance resuscitation outcomes. This discussion empowers emergency physicians to elevate their cardiac arrest response and improve patient care.

This week we discuss the presentation and treatment of hypokalemia. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Episode_61_0_Final_Cut.m4a Download Leave a Comment Show Notes Take Home Points Hypokalemia has a wide variety of presentations ranging from generalized weakness, to paralysis, to cardiac arrhythmia or cardiac arrest. When you discover hypokalemia, be sure to check and EKG. Think about underlying causes of hypokalemia, because it is rarely a solo event. Treat with oral potassium supplementation of 40-60 orally every 4-6 hours for mild hypokalemia and 10-20 mEq/hour IV for severe or symptomatic hypokalemia.

This week we discuss how to aggressively resuscitate patients with DKA as well as dispelling some dogmatic teachings on the topic. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Podcast_Episode_60_0_Final_Cut.m4a Download Leave a Comment Tags: Cerebral Edema, DKA, Hypokalemia, Insulin, Resuscitation Show Notes Take Home Points DKA should be suspected in any patient with altered mental status and hyperglycemia. Get a VBG (ABG not necessary) to confirm the diagnosis. Hypokalemia kills in DKA. Aggresively replete potassium and consider holding insulin, which drops serum potassium, until K is greater than 3.5 The insulin bolus isn’t necessary and appears to cause more episodes of hypokalemia. Just start insulin as an infusion at 0.14 units/kg Be vigilant about cerebral edema. Any change or deterioration in mental status should prompt treatment and evaluation. Mannitol in the euvolemic, normotensive patient and 3% hypertonic saline in the hypotensive/hypovolemic patient Finally, don’t forge to always hunt down the underlying cause of the DKA. Infection and non-compliance is the most common so liberally administer broad spectrum antibiotics if you’ve got even a hint of infection brewing https://www.youtube.com/watch?v=P9sKk4JZmso Additional Reading LITFL: EBM Diabetic Ketoacidosis Core EM: DKA Core EM: Episode 13.0 – Diabetic Ketoacidosis: A Case emDocs: Myths in DKA Management REBEL EM: Is There Any Benefit to an Initial Insulin Bolus in Diabetic Ketoacidosis?

This week we discuss the recognition, diagnosis and treatment of severe decompensated hyperthyroidism or thyroid storm. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Podcast_Episode_59_0_Final_Cut.m4a Download Leave a Comment Tags: Thyroid Diseases, Thyroid Storm Show Notes Take Home Points Decompensated hyperthyroidism is a rare, life-threatening condition.  It can develop in patients with long-standing untreated hyperthyroidism and is often precipitated by another event such as an infection, surgery, or trauma. Patients present with tachycardia, fever, altered mental status and GI symptoms.  Keep thyroid storm in mind if a patient has a history of hyperthyroidism or if things just aren’t making sense with your patient, you can’t find a fever source, they have fever and new afib, things like that. You’re going to use a clinical scoring tool like the Burch-Wartofsky scoring system to make the diagnosis. Treatment is three-fold. First treat the peripheral effects with propranolol.  Then prevent further synthesis of thyroid hormone with PTU and corticosteroids.  And last prevent the further release of thyroid hormone with iodine.  Be sure to hold off on giving the iodine until at least 1 hour after the patient receives PTU to avoid worsening the hyperthyroid.

This discussion dives deep into the vital role of airway management in emergency settings. The importance of achieving first-attempt success in intubation is revealed, along with strategies to minimize risks associated with multiple attempts. Listeners learn effective mnemonics for airway evaluation and the essence of clear communication within medical teams. Key preparations for intubation are emphasized, including pre-oxygenation techniques and readiness for complications. It's a lively exploration of how preparation and teamwork improve outcomes in critical situations.
