Wilderness Medicine Updates

Dr. Patrick Fink interviews Dr. Nick Daniel and Dr. Gavin Clark about an in-hospital case of exertional heat stroke in a mid-20s runner who collapsed just before the finish of an October New England half marathon in 45°F weather. EMS treated presumed SVT with adenosine, but in the ED the patient was hypotensive, profoundly diaphoretic, and altered; an oral temperature was normal while a rectal core temperature was 105.5°F, highlighting that peripheral temps can’t rule out heat stroke.

We discuss rapid “cool first” management using ice packs, misting, and fans to reach 102°F within ~30 minutes, compare cooling methods (cold-water immersion, tarp-assisted oscillation, Quantico method, frozen sheets), review labs showing lactate 9 and AKI, explain sepsis-like physiology via gut hypoperfusion, and note possible risk contribution from recent COVID and acute Lyme IgM positivity.

Forty to seventy-five percent of tourniquets placed in the field are never actually needed. In Ukraine, tourniquets left on too long during delayed evacuations have cost people limbs that the original wound never would have.

This fast push covers the new May 2026 TCCC Guidelines update and two CoTCCC training briefs on tourniquets, built around lessons from prolonged evacuations in the Russo-Ukrainian war. Topics: telling truly life-threatening bleeding from bleeding that just looks bad, the case of an 11.5-hour tourniquet that cost an arm, reassessment moving from a medic-only skill to something every responder needs, the six options at reassessment (remove, convert, reposition, tighten, add a second, leave alone), how to convert a tourniquet, and what changes once one's been on past six hours.

Takeaway: applying a tourniquet is the easy part. Knowing what to do with it for the next several hours is what actually saves the limb.

Dr. Patrick Fink reviews the spectrum of heat illness using 2024 Wilderness Medical Society guidelines, covering recognition, physiology, field treatment, and key mimics. He distinguishes heat edema, heat cramps (salt-depletion vs exercise-associated), heat syncope and exercise-associated collapse, and defines heat exhaustion by preserved mental status versus heat stroke by altered mental status in a heat context, warning not to wait for a temperature threshold. He explains heat stroke pathophysiology as direct thermal injury plus a sepsis-like inflammatory cascade from gut hypoperfusion and barrier failure, emphasizing “heat × time” and a 30-minute cooling window. Core management is “cool first, transport second,” with cold water immersion as gold standard and improvised “tarp taco” alternatives; stop cooling around 38.3–38.8°C, avoid antipyretics and dantrolene, and use fluids only as support. He highlights exercise-associated hyponatremia as a dangerous mimic requiring hypertonic saline, and discusses disposition, including possible field release after full recovery within two hours for healthy exertional cases.

That EpiPen in your kit expired eighteen months ago. Anaphylaxis is happening. Do you use it?

This episode digs into a 2025 systematic review from the American Red Cross Scientific Advisory Council that asked a question most of us have quietly wondered about: do expired resuscitation medications still work? We walk through the evidence on the four drugs that matter most in the field — albuterol, aspirin, epinephrine, and naloxone — and what the science actually says when in-date meds aren't an option.

In this episode:

• Why the expiration date is a manufacturer's guarantee, not a tombstone — and what it actually measures
• The honest limitation behind all 17 studies: this is bench chemistry, not human outcomes
• Albuterol holding 98% potency 20–30 years out, and why the inhaler's valve is the real weak link
• The aspirin asterisk: solid for years, but down to under 12% active drug at 28–40 years
• Epinephrine that's gone a little brown — discolored doesn't mean toxic, it means weaker
• The nornaloxone question, and why decades-old naloxone still isn't dangerous
• Sterility, storage, and the dashboard-baked-pen problem the studies couldn't answer
• Where the ethics land: doing something with a probably-weakened drug vs. doing nothing

The takeaway: Carry in-date meds. Rotate your stock. Store them cool and dark. But throw out the binary — in a real emergency with no alternative, that expired pen very likely still has most of its fight left.

The mountain doesn't check expiration dates. Neither does anaphylaxis.

In this episode, Dr. Patrick Fink reviews accidental hypothermia for wilderness providers, building on Ep. 27 Thermoregulation, explaining physiologic changes as core temperature falls and why accurate core temperatures are difficult to obtain in the field.

We learn the modified Swiss staging system (0–4) based on signs and symptoms and outlines field management:

- 0 cold stress (shelter, dry/insulate, warm calories; avoid alcohol),

- 1 mild hypothermia (ataxia/fine motor impairment; passive plus active external rewarming with a hypothermia wrap and heat near axilla/groin; frequent reassessment),

- 2 moderate hypothermia (confusion/lethargy; active external rewarming, evaluate hypoglycemia, gentle handling and no exertion to avoid afterdrop, cardiac monitoring, expedite evacuation),

- 3 severe hypothermia (unresponsive with vital signs; airway/ventilation support, extremely gentle transport)

- 4 hypothermic cardiac arrest (60-second pulse check, CPR, limited shocks under 30°C, withhold epinephrine/amiodarone under 30°C, consider intermittent CPR per protocol, and note potassium’s role in termination decisions).

We also briefly contrasts slow non-extracorporeal warming with ECMO/cardiopulmonary bypass, previewing a future episode on advanced care and the HOPE score

Exploring Xenon Gas for Altitude Acclimatization and Sport Performance
In this episode of Wilderness Medicine Updates, host Patrick Fink delves into the use of inhaled xenon gas for sports performance enhancement and altitude acclimatization. The discussion is prompted by a recent claim from a UK climbing team that xenon helped them achieve a rapid ascent of Mount Everest. Xenon, a noble gas traditionally used as an anesthetic, has been shown to trigger hypoxia response pathways and boost EPO levels in animal studies. However, human trials have yet to demonstrate significant performance benefits or lasting changes in blood composition. The episode also examines the safety concerns and potential risks associated with unsupervised xenon use. While xenon shows some promise, current evidence suggests it may be more of a placebo effect rather than a reliable tool for enhancing athletic performance or altitude adaptation.

In this episode, we dive into one of the most overlooked but deadly hazards in deep powder skiing: snow immersion suffocation (NARSID). Unlike avalanches, snow immersion deaths happen silently—often within feet of a groomed run—when skiers and snowboarders fall into deep snow or tree wells and become trapped. We explore the research behind these incidents, where and how they occur, who is most at risk, and the tragic mechanics of asphyxiation in deep snow. Using studies from Van Tilburg, Baugher, and Cadman, we break down ra eal survival story, discuss prevention strategies, and how both bystanders and professional rescuers should respond. Whether you’re a backcountry adventurer, resort skier, or ski patroller, this episode will change the way you think about deep snow safety. Stay aware, ski with a partner, and stay out of tree wells.

King Tube vs IGEL for Airway Management

In this episode of Wilderness Medicine Updates, Dr. Patrick Fink addresses a listener's question on whether to use a King Tube or an IGEL as an out-of-hospital airway adjunct. The episode begins with an overview of airway management techniques from mouth-to-mouth resuscitation to supraglottic airway devices. Dr. Fink explains the benefits and drawbacks of various airway adjuncts, including oral and nasal pharyngeal airways. The discussion then shifts to a detailed comparative analysis of King Tubes and IGELs based on retrospective and prospective studies. Dr. Fink evaluates the evidence indicating that IGEL may be more effective and easier to use than King Tubes, particularly in pre-hospital cardiac arrest situations. The episode concludes with recommendations for pre-hospital providers and an encouragement for listeners to share their questions and feedback.
