World Extreme Medicine Podcast

From remote surf camps in Indonesia to some of the most isolated islands in the South Atlantic, Gemma van Huyssteen has built a career shaped by curiosity, adaptability, and medicine far beyond hospital walls.
In this episode, Gemma shares her journey as a GP with extensive experience in remote, wilderness, and marine environments. She talks candidly about working in settings where evacuation can take days, resources are limited, and clinical decision-making relies as much on preparation and judgement as formal protocols.
You’ll hear about:
• Providing medical care in remote Indonesian surf communities
• Managing hazardous marine and wilderness injuries in austere environments
• Life and clinical responsibility aboard highly isolated research vessels
• Teaching and working around dive and marine-related injuries in challenging settings
• Why stepping outside conventional medical career pathways can open unexpected doors
This conversation explores what real-world remote medicine looks like, the nuance between training and lived experience, and how surfing, science, and medicine intersect in places where help is never close by.

A thoughtful, grounded discussion about building a meaningful medical career off the beaten path, and being honest about what experience really looks like in extreme environments.

In this episode, Sarah Spelsberg speaks with Luca Carenzo and Laura Leuci from Humanitas University in Milan about their research into the pre-hospital management of accidental hypothermia across Italy’s helicopter emergency medical services (HEMS).
Their nationwide survey, published in the Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, offers a detailed look at how hypothermia is managed before hospital arrival—revealing system-wide gaps, training opportunities, and practical steps for improving patient outcomes.
In this episode:
How a medical student led a nationwide HEMS research project

Why hypothermia management must start before hospital arrival

The biggest equipment and training gaps identified

The role of the “burrito wrap” in field insulation

How to balance standardisation with adaptability

Why education, simulation, and consistent training are key to progress

In this episode of the World Extreme Medicine Podcast, host Eoin Walker speaks with Corinne Palma, a recently graduated veterinarian from University College Dublin and Vice President of the International Veterinary Students’ Association.
Together, they explore how veterinary medicine extends far beyond the clinic — from field anaesthesia innovations and drone-assisted wildlife monitoring to the ethical challenges of intervention and the growing importance of One Health.
Corinne shares insights from her experience across small animal clinics, conservation projects, and research labs, and discusses the traits and training needed for the next generation of veterinarians working in extreme environments.

In this episode of the World Extreme Medicine Podcast, host Eoin Walker speaks with Simon Robinson, former Royal Marine Commando Paramedic turned Head of Clinical Development in Urgent Care.
Together, they explore the evolving role of paramedics in primary care, from emergency response to diagnosis, prescribing, and leading multidisciplinary teams. Simon shares insights on:
The transition from frontline emergency work to primary care

Independent prescribing and clinical autonomy

Training, mentorship, and building multidisciplinary teams

The challenges and opportunities paramedics face outside traditional ambulance roles

Whether you’re a student paramedic, an experienced clinician, or simply curious about the future of urgent care—this conversation offers an honest, practical look at how the profession is growing beyond its emergency roots.

In this episode of the World Extreme Medicine Podcast, we explore one of the most talked-about studies in pre-hospital trauma care: “Beyond IO and IV - Trauma Lines in Pre-Hospital Haemorrhagic Shock.”
Host Eoin Walker is joined by Paolo Pallavicini, final-year medical student and research fellow with London’s Air Ambulance and the Centre for Trauma Sciences, to unpack a groundbreaking study analysing over 8,000 trauma patients.
They discuss:
Why standard IV and IO access can be inadequate in exsanguinating trauma

How trauma lines can double pre-hospital blood delivery rates

Success, complication, and survival outcomes from the study

The future of central venous access in pre-hospital care

Paolo also offers key insights into the realities of working in a chaotic roadside environment, the importance of governance and training, and how clinical risk-benefit decisions are made when every second counts.
