Zworth Reading Issue #9

This episode walks through five emergency medicine reads from the week of June 8, 2026, with a focus on separating useful clinical signal from misleading noise. It argues that most ED return visits are not errors and that bounce-back rates are a poor blunt quality metric; reviews the weak evidence for routine antibiotics in uncomplicated strep throat and makes the case for more shared decision-making; highlights that the new ACR epigastric pain guidance mostly confirms current practice, especially CT for suspected perforation and restraint for low-risk dyspepsia; summarizes two critical care papers showing that refractory septic shock identifies a very high-mortality group and that delays to antibiotics in neutropenic sepsis worsen outcomes; and closes with a sober look at ambulance offload delays, noting that while they clearly prolong ED stays and likely cause harm, the evidence for direct mortality impact remains surprisingly thin.  *This episode came in out of sync - we apologize for the numbering.*

This episode highlights three practical EM takeaways: current evidence does not show supraglottic airways outperform bag-valve-mask ventilation for BLS providers in cardiac arrest, acute liver failure requires early recognition and escalation, and aggressive blood pressure lowering after successful thrombectomy may be harmful. Overall, it’s a quick, high-yield weekly update emphasizing solid fundamentals, source-based caution where evidence is thin, and awareness of adjacent-specialty data that can shape ED decision-making.

This episode of Zworth Reading: Max's EM Weekly Update explores critical developments in emergency medicine, highlighted by a prospective study suggesting that an initial 12 mg dose of adenosine significantly improves first-dose conversion rates for stable SVT compared to the traditional 6 mg dose. The update also reviews clinical insights regarding pediatric stroke diagnostic delays, the impact of semaglutide on alcohol use disorder, and critical methodology critiques of recent airway management and pulmonary embolism data.

You’re about to hear a rapid, high-yield roundup of this week’s most relevant emergency medicine studies and clinical reviews, including naloxone in PEA arrest, bicarbonate for severe metabolic acidosis, alcohol withdrawal, lower GI bleeding, pulmonary arterial hypertension, and sepsis-related atrial fibrillation. Along the way, I’ll highlight what may actually change bedside practice, what remains uncertain, and where observational data deserves a more skeptical read.

The ZWORTH Reading: Max’s EM Weekly Update (Issue #6) podcast delivers a concise, evidence-based breakdown of the latest developments in Emergency Medicine and critical care. This week's core focus highlights two major pediatric studies that challenge or reinforce current clinical practices. First, a multicenter randomized controlled trial evaluating azithromycin for preschoolers presenting to the ED with moderate-to-severe wheezing was stopped early for futility, demonstrating that the antibiotic offers zero clinical benefit regardless of whether pathogenic bacteria are present. Conversely, a robust systematic review of nearly 68,000 pediatric sedations confirms that IV ketamine is extraordinarily safe for ED procedural sedation, experiencing zero deaths and minimal serious adverse events. The review notes that mild upper respiratory infections or coadministered benzodiazepines should not deter clinicians from utilizing it confidently. Beyond pediatric care, the update explores practical clinical frameworks and critiques nationwide data to optimize emergency responses. In the realm of clinical reviews and skills, the podcast covers toxicological pearls for managing kratom presentations and provides techniques for expanding aortic point-of-care ultrasound (POCUS) to better detect thoracic pathology. For adjacent specialties, an expert consensus outlines critical airway management strategies for obese patients, emphasizing aggressive pre-oxygenation with non-invasive ventilation (NIV) and routine video laryngoscopy. Finally, the session flags a major prehospital methodology study comparing intranasal versus intramuscular naloxone. While the headline suggests IM superiority, the podcast raises important cautionary flags regarding unmeasured confounders and confounding by indication, concluding that while both routes remain entirely reasonable, the observational data cannot definitively establish one as superior.

The National Academy of Medicine outlines a Code of Conduct (AICC) framework for the responsible development and application of Artificial Intelligence (AI) in health and medicine. This framework aims to address challenges like rising healthcare costs and staff shortages while ensuring AI's transformative potential is realized ethically. Key to the AICC are Code Commitments, focusing on advancing humanity, ensuring equity, engaging individuals, improving workforce well-being, monitoring performance, and fostering innovation. The document also details Code Principles for health AI governance and assigns specific roles to various stakeholders—from AI developers and researchers to patients and federal agencies—to ensure the safe, effective, and equitable integration of AI into healthcare.

Comprehensive overview of "red eye", a common ophthalmic complaint, emphasizing the differentiated diagnostic and management approaches required for adult and pediatric populations. It outlines the etiology, clinical presentation, and diagnostic challenges associated with red eye, ranging from benign conditions like conjunctivitis to sight-threatening emergencies such as acute angle-closure glaucoma or orbital cellulitis. The sources highlight the importance of systematic clinical evaluation, including detailed history taking, a thorough ocular examination (utilizing the VVEEPP mnemonic and specialized tools like the slit lamp), and appropriate ancillary tests (like fluorescein staining and imaging studies). Furthermore, the text addresses specific management principles like pain relief, the use of mydriatic agents, and antimicrobial strategies, always stressing the critical need for age-specific considerations and prompt ophthalmologic consultation for high-risk cases, particularly in pediatric patients where conditions like child abuse are also considered.

Pediatric Resuscitation: this podcast offers an in-depth look at emergency care for children, focusing on three critical areas. Addresses pediatric shock and arrest, detailing its principles, causes, survival rates, and the importance of high-quality, uninterrupted compressions and ventilations. We examines septic shock in children, highlighting its prevalence, varying hemodynamic presentations, and the crucial role of timely fluid resuscitation and antibiotic administration. Finally, we discuss Brief Resolved Unexplained events (BRUE's), outlining their presentation, diagnostic considerations, and disposition strategies, while also emphasizing the benefits of family presence during pediatric resuscitations.

A comprehensive overview of procedural sedation and analgesia (PSA), specifically focusing on pediatric patients. They detail the historical evolution of pain and sedation management, including the development and re-evaluation of various sedative and analgesic agents like propofol, ketamine, and opioids, alongside local and topical anesthetics. The texts also highlight best practices in pain assessment and nonpharmacologic interventions, such as the use of child life specialists and parental presence. Furthermore, they address monitoring protocols, safety considerations, and the ongoing challenge of oligoanesthesia (undertreatment of pain), emphasizing its negative consequences and outlining the roles of key organizations in shaping clinical guidelines.

We explore the significant stressors and challenges faced by emergency medicine physicians, including high rates of burnout, traumatic exposures, and demanding work conditions. They introduce Stephen Covey's "Inside-Out" paradigm as a foundational philosophy emphasizing character ethics and personal responsibility for navigating these pressures. The texts then explain how each of Covey's "7 Habits of Highly Effective People"—such as Be Proactive and Sharpen the Saw—can be specifically applied to help emergency physicians enhance their effectiveness, improve well-being, and contribute beyond direct patient care through leadership, research, and advocacy. Ultimately, the sources suggest that adopting these principles can lead to greater resilience and better patient outcomes in this high-stress medical specialty.
