REBEL MIND Ep6 – How to Sleep When the World Says You Can’t
REBEL Cast
🔑Key Points ☕ Try the coffee nap! Where you combine caffeine and a 30-minute nap to then have that boost energy and alertness by the time it kicks in. 💤 Sleep isn’t optional—it’s crucial for memory, mood regulation, and physical recovery. It is fundamentally different from rest ❌ Replacing sleep with caffeine isn’t effective and can have negative health impacts. Make getting enough sleep a priority 🌞 Sunlight exposure is important for maintaining circadian rhythms and sleep quality. This applies even if you work as a nocturnist 💡 Creating a personalized sleep...

REBEL Core Cast 150.0: Emergency Medicine Consults: How to Call a Consult + Handle Pushback
REBEL Cast
In this episode of Rebel Core Content, Swami breaks down one of the most important (and most underrated) skills in emergency medicine: how to give a clean, effective consult—and what to do when you get pushback. Learn a simple 4-step framework to structure every consult (introduce yourself, lead with the ask, give a focused summary, and close the loop), plus ready-to-use scripts for common scenarios. We also cover how to respond to refusals, keep conversations professional, and escalate appropriately when patient safety or disposition is at risk.

REBEL CAST: The RSI Trial – Ketamine vs Etomidate in Rapid Sequence Intubation
REBEL Cast
REBEL Cast: The RSI Trial — Ketamine vs Etomidate in Critically Ill Adults In this episode, we break down the 2025 NEJM RSI trial comparing ketamine and etomidate for tracheal intubation in critically ill adults (Casey et al., PMID: 41369227). This multicenter randomized trial enrolled 2,365 patients across ED and ICU settings and asked a clinically important question: does ketamine improve 28-day mortality compared with etomidate? What we cover: Primary outcome: no statistically significant difference in 28-day mortality Secondary signal: higher “cardiovascular collapse” with...

REBEL CAST - RENOVATE Trial: HFNC vs BPAP in Acute Respiratory Failure
REBEL Cast
📌 Key Points 💨 HFNC met criteria for non-inferiority to BPAP for preventing intubation or death within 7 days in four of the five ARF subgroups. 🧪 Bayesian dynamic borrowing increased power across subgroups but created variable certainty, especially in smaller groups such as COPD. 🫁 The immunocompromised hypoxemia subgroup did not meet non-inferiority, leading to early trial stopping for futility. ⚖️ Rescue BPAP use, subgroup-specific exclusion criteria, and non-standardized BPAP delivery are important contextual factors that influence...

REBEL MIND Ep4 – Rest Is Not Sleep: The Seven Dimensions of True Recovery
REBEL Cast
🗝️Key Points Rest isn’t a luxury; it’s a necessity and differs significantly from sleep in terms of mental and physical recovery needs. Uncovering the seven types of rest can highlight diverse needs: physical, mental, sensory, creative, emotional, social, and spiritual. Rest from high-stress environments such as the ED is crucial for reducing exhaustion, enhancing decision-making, and maintaining empathy. The necessity for intentional rest: tailor your rest strategies to meet personal recharge needs effectively. Rest should be deserved, not...

REBEL Core Cast 149: Review of Corticosteroids in Community-Acquired Pneumonia
REBEL Cast
🗝️ Key Points 💉 Hydrocortisone Saves Lives: The 2023 Cape Cod Trial (NEJM) showed a clear mortality benefit and reduced need for intubation in severe CAP patients treated with hydrocortisone. 📊 Guidelines Are Catching Up: The SCCM (2024) and ERS now recommend steroids for severe CAP, while ATS/IDSA updates are still pending. 🔥 Redefining “Severe”: Patients requiring high FiO₂ (>50%), noninvasive or mechanical ventilation, or PSI >130 meet criteria for steroid therapy — even outside the ICU. 🍬 Main Risk = Hyperglycemia: Elevated glucose was the most...

info_outline🗝️Key Points
- 💧 Fluid Choice Matters: Plasma-Lyte, a balanced crystalloid, corrected acidosis faster than normal saline in severe DKA patients, with no increase in adverse events.
- 🧪 Chloride Load Concerns: Normal saline’s high chloride content can worsen acidosis, potentially slowing bicarb recovery even after the anion gap closes.
- 🔬 Study Design Strengths: The SCOPE-DKA trial was a cluster crossover, open-label RCT, protocolizing all variables except fluid type, enhancing the reliability of its findings.
- 🧮 Base Excess & Strong Ion Difference: Base excess/deficit and strong ion difference are valuable but underutilized tools for assessing acid-base status—don’t rely solely on pH or bicarb.
- ⚠️ Limitations & Next Steps: The study did not include lactated Ringer’s, and fluid rates were left to clinical discretion. More research, including three-arm trials, is needed for definitive guidance.
📝 Introduction
Managing diabetic ketoacidosis (DKA) requires careful consideration of fluid therapy, especially in severe cases. In part two of our REBEL Cast DKA series, we shifted from insulin strategies to fluid choice in severe DKA, diving into the SCOPE-DKA trial—a cluster, crossover, open-label RCT from Australia. While normal saline (NS) is commonly used, concerns about its high chloride content and impact on acidosis have sparked growing interest in balanced solutions like Plasma-Lyte.
🚨 Clinical Bottom Line
Plasma-Lyte showed a modest but meaningful benefit over normal saline in resolving metabolic acidosis in patients with severe DKA. Though safety profiles were similar, the more balanced electrolyte composition of Plasma-Lyte helped normalize acid-base status slightly faster—without worsening ketosis. While this won’t revolutionize care overnight, it’s one more step toward physiologic resuscitation in DKA. Understanding fluid composition and its impact on acid-base balance is crucial for optimal patient care.
