Most podcasts are about understanding. This emergency medicine podcast is about knowledge recall. Active learning requires your brain to process actively. Can you withstand sitting with the discomfort of being asked a question until you can answer it easily and readily? I promise you won’t be comfortable listening to each episode, but after you withstand the discomfort, your ability to recall, will be far superior than any other passive, listening.

Sickle Cell Crisis: 4 R’s Mnemonic — Recognize, Reverse, Radiology, Refer

In the fast-paced, high-stakes world of emergency medicine, every second matters—especially when it comes to sickle cell crisis.

This podcast takes you straight to the heart of what matters most for ED clinicians, walking you through the essential “4 R’s” that can mean the difference between stabilization and rapid deterioration:

• Recognize — Identify the telltale signs of sickle cell crises early. Understand presentations like acute pain episodes, acute chest syndrome, stroke, and splenic sequestration, and learn how to differentiate these from other causes of acute pain or respiratory distress.

• Reverse — Act fast to correct life-threatening complications. From oxygen and aggressive IV fluids to urgent infection management, you’ll get evidence-based, bedside-ready strategies to halt progression.

• Radiology — Know when and why to image. From chest X-rays in acute chest syndrome to brain imaging for suspected stroke, we’ll break down which modalities to order—and how to interpret findings in the sickle cell patient.

• Refer — Recognize when escalation of care is critical. Whether to hematology, critical care, or transfer to a higher-level facility, we’ll cover the decision-making process and timing.

Hosted with a focus on clinically relevant, ED-ready pearls, each episode blends:

• Case-based storytelling — Putting you in the room with the patient, step-by-step.

• Mnemonic-rich recall tools — Like our “crime scene outline” visual, with key stickers marking the 4 R’s across the patient’s limbs for fast memory anchoring.

• Practical takeaways — What you can do immediately, what you must watch for, and what to avoid.

The principles behind the Sickle Cell 4 R’s is delivered in a no-fluff, high-yield format designed for busy clinicians who want to sharpen their edge in real emergencies.

Whether you’re a seasoned emergency medicine provider, a resident looking to solidify your sickle cell knowledge, or simply someone passionate about critical care, Sickle Cell Crisis: The 4 R’s will give you the skills and confidence to take decisive action when it matters most.
