The QT interval is a vital part of ECG interpretation, reflecting the heart’s electrical recovery after each beat. When prolonged, it can set the stage for torsades de pointes. Understanding how to measure and correct the QT interval, identify high-risk medications, and act quickly when TdP occurs is essential for every clinician. This guide walks you through the physiology, interpretation, common causes, and emergency management of QTc prolongation to keep your patients safe.

In this episode of the Rebel Core Content podcast, Swami provides crucial tips on using tourniquets. Highlighting the significance of these life and limb-saving devices, the discussion focuses on the optimal placement of tourniquets, emphasizing placing them 2-3 inches (5-6 cm) above the bleeding source and avoiding joints. Swami also advises on the correct way to tighten the tourniquet using the Velcro strap first, followed by minimal use of the windless. The importance of noting the application time to avoid prolonged arterial flow interruption is also discussed. The episode concludes with a reminder to visit the podcast's website for more valuable content.

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.

In this episode of REBEL Cast, we dive into part one of our Diabetic Ketoacidosis (DKA) series with a twist—subcutaneous insulin instead of the traditional IV drip. We explore the SQuID Protocol (Subcutaneous Insulin in DKA), which could potentially shift how we manage mild to moderate DKA—from the ICU to the general floor.

When you take the airway, you take the wheel and you now control the patient’s oxygenation and ventilation. In this REBEL Crit episode, Dr. Lodeserto and Dr. Acker walk through the physiology, ventilator strategies, and clinical curveballs that separate calm control from chaos at the bedside.

Mechanical ventilation can feel overwhelming, especially when faced with a sea of ventilator modes and unfamiliar terminology. In Part 2 of the series, we go beyond breath types and delivery mechanics to explore the most used modes in the ICU. We will break down each one; explaining how it works, when to use it, and why the goal isn’t the “best mode” but the most comfortable one for the patient.

In this special episode of Rebel Cast, we spotlight the Incrementum Conference in Spain, a significant event in emergency medicine. Hosts welcome Dr. Francisco 'Paco' Campillo Palma and Dr. Carmen Maria Cano, founders of Incrementum, to discuss the recognition of emergency medicine as a specialty in Spain. They share their journey of creating the conference, emphasizing the importance of education, collaboration, and growth. The discussion also touches on this year's conference highlights, including sessions on mental health and evidence-based medicine, and the exceptional lineup of speakers. Listeners are encouraged to attend the conference in April 2026 for an enriching experience.

For many medical residents, the ICU can feel like stepping into a pressure cooker. At the heart of that stress often lies one intimidating machine: the ventilator. Rather than diving headfirst into complex ventilator modes, this episode lays a critical foundation by breaking down the basic building blocks of mechanical ventilation, something every clinician should master before moving on to more advanced concepts. Once you know the 3 types of breaths and how those breaths are delivered, you can more easily understand most of the mechanical ventilator modes.
