2026/03/04

Today we are exploring the imperative topic of rest and why it’s not just about sleeping. The first of a two part series, hosted by Dr. Mark Ramzy with guests Dr. Maureen Aiad and Dr. Amil Badoolah, our discussion sheds light on the multifaceted nature of rest, especially in the demanding field of emergency medicine.

The optimal treatment strategy for intermediate-risk (submassive) pulmonary embolism remains controversial. These patients are not in shock, but they have right ventricular (RV) dysfunction and myocardial injury, which are associated with higher risk for clinical decompensation and adverse outcomes.

Procalcitonin is a protein that is upregulated during inflammatory states. An elevation in procalcitonin should be specific to bacterial infections. Viral infections should result in decreased procalcitonin levels thus allowing us to differentiate bacterial from viral and help guide antibiotic prescription. However, this differentiation isn’t what we see in real life data.The post Clinical Conundrum: Is Tamsulosin Effective in Increasing Spontaneous Passage Rate of Ureteral Stones? appeared first

2026/02/16

The cornerstone of acute ischemic stroke (AIS) management involves timely reperfusion of the ischemic brain tissue. Intravenous thrombolysis with alteplase has been the standard of care for AIS within 4.5 hours of symptom onset, based on pivotal trials such as NINDS and ECASS III, which demonstrated improved functional outcomes despite an increased risk of intracerebral hemorrhage. However, many patients present outside this narrow therapeutic window, excluding many patients from the potential

Continuous Suctioning Doesn’t Hasten Hypoxemia

2026/02/09

Prior research has shown that deep tracheal suctioning can result in more rapid development of hypoxemia. It is unclear if continuous suctioning during intubation poses a similar risk. Does the application of continuous suctioning during rapid sequence intubation (RSI) result in more rapid deoxygenation?The post Continuous Suctioning Doesn’t Hasten Hypoxemia appeared first on REBEL EM - Emergency Medicine Blog.

Corticosteroids have long sparked debate in the treatment of bacterial pneumonia — once viewed with skepticism, now increasingly supported by high-quality evidence. In this episode, Dr. Alex Chapa joins the REBEL Core Cast team to explore how the 2023 Cape Cod Trial (NEJM) reshaped practice and guideline recommendations for severe community-acquired pneumonia (CAP).The post REBEL Core Cast 149: Review of Corticosteroids in Community-Acquired Pneumonia appeared first on REBEL EM - Emergency Medicine

Seizing the Evidence: Should We Consider Ketamine’s...

REBEL EM – Emergency Medicine Blog ·

2026/01/21

Ketamine was first introduced for human use in 1965 and has been widely utilized as a general anesthetic with an excellent safety profile (Mion 2017, Dorandeu 2013). Ketamine works on several receptors, resulting in various actions such as anesthesia, analgesia, and antidepressant effects. While not widely studied, ketamine has been shown to have antiepileptic properties. In seizures, the excessive release of glutamate leads to the overactivation of N-methyl-D-aspartate (NMDA) receptors, thereby

2026/01/19

With high flows, modest PEEP, and effective dead-space washout, HFNC can improve oxygenation and decrease work of breathing while preserving the ability to talk, cough, eat, and interact with staff and family. The RENOVATE trial set out to answer a high-impact question across five distinct etiologic groups: Is HFNC non-inferior to BPAP (NIV) for preventing intubation or death in acute respiratory failure?

Non-invasive ventilation (NIV) refers to respiratory support provided without endotracheal intubation. The most common modalities include continuous positive airway pressure (CPAP), bilevel positive airway pressure (BiPAP), and high-flow nasal cannula (HFNC). These therapies aim to improve oxygenation, reduce the work of breathing, and potentially prevent invasive mechanical ventilation.The post REBEL Core Cast 148.0–Demystifying Non-Invasive Ventilation & HiFlow appeared first on REBEL EM -

2026/01/08

Etomidate or ketamine? The debate over the ideal agent for emergency rapid sequence intubation (RSI) has raged for years with no clear winner. Etomidate has been touted in the past for its rapid onset and minimal intrinsic effects on hemodynamics. However, the drug is well known as a transient adrenal suppressant though the impact of this suppression isn’t clear. Ketamine has risen in recent years as an alternative, due to its perceived hemodynamic stability, analgesic properties and absence of

In this episode and blog post, hosts Mark Ramzy and Kim Bambach (Assistant Professor of Emergency Medicine, The Ohio State University) explore a deceptively simple question: How accurately can we assess our own performance? The answer hinges on a classic cognitive bias that touches all of us in emergency medicine.

REBEL EM – Emergency Medicine Blog ·

2026/01/05

Shock is a life threatening condition that requires rapid resuscitation, and targeted treatment. Due to its complex nature, shock management poses many challenges for physicians in the acute care setting, more specifically, in the emergency department (ED). Point-of-care-ultrasound (POCUS) has emerged as a promising diagnostic and therapeutic clinical tool in this context, allowing ED physicians to assess hemodynamics and guide treatment interventions in real-time at the bedside.The post POCUS Use

2025/12/29

Rib fractures are among the most common injuries in older trauma patients and can look deceptively “benign” early—until pain-limited ventilation, atelectasis, pneumonia, and respiratory failure develop hours to days later. Disposition decisions based on fracture count alone often miss the interaction between anatomic injury burden and physiologic reserve, especially in frail patients with limited pulmonary “margin.” RibScore offers an anatomy/CT-based estimate of pulmonary complication risk, while

2025/12/24

Annual influenza cases exceed one billion worldwide, with the vast majority of patients experiencing mild to moderate severity of illness. This massive health burden explains the extensive research into antivirals, including oseltamivir (Tamiflu). Initial studies supported the utility of oseltamivir for preventing complications, hospitalization and shortening disease course in patients with mild to moderate influenza. However, subsequent analysis determined that Roche (the manufacturer of

Antithrombotic therapy is a cornerstone in the treatment of atrial fibrillation (AFib), though it carries a significant risk of bleeding. While Vitamin K antagonists (VKAs), the oldest anticoagulants, were largely supplanted by direct oral anticoagulants (DOACs) following trials like ARISTOTLE and ROCKET AF, the risk of bleeding with these newer agents still exists.Enter Abelacimab, a novel drug designed to provide thrombosis protection while minimizing the impact on hemostasis.

Nausea with or without vomiting is very common in early pregnancy, affecting approximately 70% of pregnancies (Maisal 2012). Hyperemesis gravidarum is a severe form of nausea and vomiting in pregnancy that can lead to significant maternal dehydration, electrolyte abnormalities, and weight loss if not properly managed. Pharmacologic treatment is crucial to break the cycle of vomiting, restore oral intake, and prevent complications such as Wernicke’s encephalopathy or hospitalization. Timely and

Ventilator management can feel overwhelming—there are so many knobs to turn, numbers to watch, and changes to make. But before adjusting any settings, it’s crucial to understand why the patient is in distress in the first place, because the right strategy depends on the underlying cause. In this episode, we’ll walk through three different cases to see how the approach changes depending on the problem at hand.The post REBEL Core Cast 146.0–Ventilators Part 4: Setting up the Ventilator appeared first
