Wed, 03 Apr 2024 - 34min - 285 - REBEL Cast Ep125: 1st 48 Hours of PE Management – How Good Is Unfractionated Heparin?
Background: The mainstay of treatment for symptomatic pulmonary embolism (PE) is anticoagulation (AC). Patients with higher-risk PE may require advanced interventions such as thrombolytic therapy, surgical thrombectomy, or even extracorporeal membrane oxygenation (ECMO). Because of its short half-life and availability of a reversal agent, unfractionated heparin (UFH) is commonly used when percutaneous or surgical interventions ... Read more
Mon, 01 Apr 2024 - 17min - 284 - REBEL Cast Ep124: Nitrates in Right Sided MIs?
Background: Nitrates can help improve symptoms and ischemia in the setting of acute myocardial infarction. Current teaching holds that nitrates should be avoided in patients with potential right ventricular myocardial infarction (RVMI), due to the risk of decreasing preload and precipitating hypotension. This belief is based on a single 1989 study of 40 patients with ... Read more

Wed, 07 Feb 2024 - 5min - 281 - REBEL Cast Ep123: Reduced-Dose Systemic Peripheral Alteplase in Massive PE?
Background: Massive pulmonary embolism defined as sustained hypotension (SBP <90mmHg) has a high mortality which is why early recognition and thrombolytic therapy is typically recommended (AHA Class IIA; ESC Class IB) [1]. However, full-dose thrombolytic therapy (Alteplase 100mg (IV) is associated with an increase in bleeding [2]. Because the lungs receive 100% of cardiac output, it has ... Read more

Wed, 29 Nov 2023 - 24min - 275 - REBEL Core Cast 110.0 – On Shift Learning Pearls
Take Home Points: Patients with recent onset atrial fibrillation can safely be cardioverted if they are 1) on anticoagulation 2) Low risk based on CHADS-VASC with onset < 48 hours or 3) High risk based on CHADS-VASC with onset < 12 hours. In anaphylaxis, think, “If A, B or C, give E.” If the patient ... Read more
Wed, 11 Oct 2023 - 11min - 274 - REBEL Core Cast 109.0 – Na Channel Blocker Poisoning
Take Home Points: In the context of poisoning, a “wide QRS” is anything greater than 100 milliseconds. A newly “wide QRS”, especially with hemodynamic instability, should prompt consideration of sodium channel blockade and not ventricular tachycardia. Treatment is guided by administration of sodium-bicarbonate. Recall that the resultant alkalemia driven by sodium-bicarbonate will shift potassium intracellularly. ... Read more
Wed, 27 Sep 2023 - 10min - 273 - REBEL Core Cast 108.0 – Angioedema
Take Home Points: Airway management is paramount; expect a challenging intubation and consider controlling the airway early if there is apparent airway compromise. Understanding the cause of angioedema (mast cell vs. bradykinin mediated) helps dictate directed management. Urticaria and pruritus = MAST CELL mediated, which is treated like a standard allergic reaction. REBEL Core Cast ... Read more

Traditional RSI entails preoxygenation followed by ... Read more
Mon, 07 Aug 2023 - 19min - 269 - REBEL Cast Ep121: The Battle of the Blades – Video Laryngoscopy vs. Direct Laryngoscopy
Background: The ongoing debate between video laryngoscopy (VL) and direct laryngoscopy (DL) has ignited intense debate within the emergency medicine and critical care communities.

Mon, 31 Jul 2023 - 26min - 268 - REBEL Core Cast 105.0 – Methylxanthine Toxicity
Take Home Points Methylxanthines are a drug class that includes caffeine, theophylline, and theobromine. The three main mechanisms that account for the clinical presentation of methylxanthine toxicity are: catecholamine release, adenosine antagonism, and phosphodiesterase inhibition. Beta agonism will lead to hyperlactatemia, hypokalemia, hyperglycemia, and tachycardia. Adenosine antagonism may lead to seizures and/or supraventricular tachycardia that ... Read more

Thu, 29 Jun 2023 - 33min - 264 - REBEL Cast Ep 118: The PROCOAG Trial – 4F-PCC for Trauma Patients?
Background: Hemorrhage is the leading cause of mortality in trauma patients. Interventions such as early application of hemorrhage control, tranexamic acid, reduction of crystalloid fluid administration and balanced ratio blood product transfusion have improved many patients’ outcomes. However, mortality still remains high due to trauma-induced coagulopathy. Some clinicians have advocated for early administration of 4-factor ... Read more
Mon, 26 Jun 2023 - 16min - 263 - REBEL Core Cast 103.0 – Caustic Ingestions
Take Home Points Caustics are substances that injure tissue upon physical contact. Caustic potential is not purely a function of pH. The decision to admit is dependent on the history and physical. Vomiting, drooling, and stridor are concerning. Stridor alone or 2/3 symptoms should warrant admission and gastroenterology consultation for potential endoscopy. The lack of ... Read more

Wed, 08 Mar 2023 - 7min - 253 - REBEL Cast Ep114: High Flow O2, Suspected ACS, and Mortality?
Background: Historically, we have treated acute coronary syndrome with supplemental oxygen regardless of the patient’s oxygen saturation. This intervention was based on the belief that pushing the patient’s PaO2 to supra therapeutic levels would increase O2 delivery to ischemic myocardium and help reduce myocardial injury. More recent evidence, however, demonstrates that too much oxygen could ... Read more
Thu, 02 Mar 2023 - 19min - 252 - REBEL Cast Ep113: Defibrillation Strategies for Refractory Ventricular Fibrillation
