FOAMed has changed emergency medicine by accelerating knowledge translation. But there’s a downside: when learning is driven mostly by what’s new—or what’s popular—you can develop uneven foundational knowledge.
That’s why we created REBEL Core. While REBEL EM will continue to critically appraise new research, REBEL Core is dedicated to the core concepts that support great bedside care across the entire spectrum of emergency medicine and critical care—not just the headline areas like ECGs, ultrasound, resuscitation, and procedures.
Our goal is to help you build a strong, complete foundation—so you can apply both classic principles and new evidence with confidence.
Take Home Points: Know clinical (cold extremities, oliguria, confusion, dizziness, narrow pulse pressure) and laboratory markers (metabolic acidosis, elevated creatinine, lactic acidosis) of hypoperfusion. An elevated lactate is a danger sign and requires explanation. Norepinephrine is a great first line ...
Take Home Points: Carbon monoxide is a colorless, odorless, and tasteless gas that results from incomplete combustion of any carbon containing product. Exposure often occur unintentionally from indoor use of gas powered generators, camp stoves, or faulty home heaters. The ...
How Long Should We Monitor After Giving IM Epinephrine for Anaphylaxis? Bottom Line Up Top: After prompt recognition and appropriate treatment with IM epinephrine, the risk of biphasic reactions are exceedingly low. There is no set observation time to monitor ...
Take Home Points: All STEMIs should be loaded with dual antiplatelet therapy. Prasugrel (Effient) is avoided as there is an increase in bleeding complications if the patient requires a CABG. NSTEMI cases can be challenging to manage. Consult Cardiology early ...
Take Home Points: Dose your RSI meds correctly. Reach for post-intubation sedation at the same time you are asking for your induction agent and paralytic. Propofol is a great choice for post-intubation sedation, and if your patient becomes hypotensive do ...
Take Home Points: A CCTA is an anatomic test to determine if a patient has normal coronary arteries, non-obstructive disease, or obstructive disease. The warranty period for a CCTA is anywhere from 3-10 years depending on the characteristics of the ...
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 < ...
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 ...
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 ...
Take Home Points Clinical presentation is very nonspecific; evaluate all patients presenting with back pain for infectious risk factors. Baseline labs should not guide diagnosis, but may assist in later management. MRI is key to diagnosis, obtain this imaging in ...
