2025/11/10

Status epilepticus is traditionally defined as a seizure lasting ≥5 minutes or recurrent seizures without return to baseline in between. It is a neurologic emergency associated with increased morbidity and mortality the longer it persists. Some complications include cardiac arrhythmias, respiratory failure, aspiration pneumonia, and recurrent status epilepticus. The established treatment paradigm includes first line treatment with benzodiazepines (midazolam IM, lorazepam IV, diazepam IV). Second

Predicting severity in acute pancreatitis matters — it guides where patients go, how closely we watch them, and how aggressively we manage fluids and complications. Two of the most commonly used tools are Ranson’s Criteria and the BISAP Score.Ranson’s offers a comprehensive, data-rich assessment once labs and time points are available, while BISAP gives a fast, bedside estimate of mortality risk that’s perfect for the early phase of care.

Treatment for Alcohol Use Disorder

REBEL EM – Emergency Medicine Blog ·

2025/10/16

Emergency medicine physicians were trailblazers during the opioid epidemic, and now we have the same opportunity with alcohol use disorder (AUD). Treating AUD deserves the same attention we give to opioid overdose, diabetic ketoacidosis, or hypertensive emergencies. Even when alcohol use doesn’t present as an immediate crisis, each ED encounter is a chance to intervene—one that could help prevent future withdrawal, traumatic injury, or upper gastrointestinal bleed. Naltrexone and other Medications

Screening for Alcohol Use Disorder

2025/10/13

Each year, about 1 in 7 men and 1 in 11 women in the United States meet criteria for alcohol use disorder (AUD)—affecting nearly 29 million people, roughly the entire population of Texas. Patients with AUD face staggering health risks: they are 3.5 times more likely to die than the general population, and their life expectancy is up to 25 years shorter. Over the past decade, alcohol-related emergency department (ED) visits have climbed by nearly 50%. Between 2021 and 2023 alone, alcohol accounted

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.The post REBEL Core Cast – DKA: Beyond the Basics Part 2 – SCOPE DKA-Trial appeared first on

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: What is the Utility of Procalcitonin in the ED? appeared first on REBEL EM - Emergency Medicine

Hemoptysis is a potentially life-threatening emergency that can lead to airway compromise and hemorrhagic shock. While definitive treatments like bronchoscopy, bronchial artery embolization (BAE), and surgery can be effective, they often require significant time and specialized resources—capabilities not universally available in all hospitals or emergency departments.Tranexamic acid (TXA), an antifibrinolytic agent, has emerged as both an adjunctive and potentially definitive therapy in the acute

The sicker the patient, the more likely an IO line is the right choice. In emergencies such as cardiac arrest or hemorrhagic shock, the speed and reliability of IO access outshine traditional intravenous (IV) or central line placements. There's virtually no resuscitation medication or blood product that cannot be administered through an IO, making it indispensable in life-threatening scenarios.

2025/08/25

Syncope is one of the most common complaints we face in the ED. Most patients do well, yet a small subset are harboring serious cardiac or neurologic disease. Admit everyone, and we waste beds and resources; discharge everyone, and we risk missing life-threatening disease. As always in emergency medicine, we’re searching for the needle in the haystack—the one patient out of hundreds who’s truly at risk.You may have heard of the San Francisco Syncope Rule, but have you met its worthy opponent, the

Sepsis is one of the most common emergencies we encounter, yet despite decades of research, it still carries a high burden of morbidity and mortality. Over the years, our attempts to improve outcomes have spanned the spectrum—from clearly lifesaving (like timely antibiotics) to largely discredited (like high-dose vitamin C).On paper, treatment with albumin makes sense: it’s a large protein that can boost oncotic pressure and theoretically counteract sepsis-induced capillary leak. But when tested in

2025/07/28

Diagnosing PE in the emergency department is tricky. The symptoms—chest pain, shortness of breath, tachycardia—are nonspecific and overlap with many other conditions. But missing a PE can have devastating consequences, so there’s often a low threshold to order a CTA. Resulting in over-testing, radiation exposure, contrast risk, increased length of stay, and unnecessary healthcare costs. Wells Criteria and PERC help clinicians safely and systematically identify which patients actually need further

Managing patients with suspected occult scaphoid fractures and normal X-rays presents a common clinical dilemma. About 1 in 10 of these patients will have an occult fracture, and roughly 10% of all scaphoid fractures result in nonunion. However, the risk of nonunion among patients with MRI-confirmed occult fractures is much lower—around 3.5%.Guidelines recommend immobilization with a thumb spica cast or splint when clinical suspicion is high. But that threshold is subjective, and snuffbox

Chest pain is one of the most common—and anxiety-inducing—presentations in the Emergency Department. With millions of visits each year, clinicians face the constant challenge of identifying who is having a major cardiac event and who can safely go home. While most of these patients won’t have acute coronary syndrome, the stakes for missing it are high.
