Quick takeaways

Hyperbaric medicine has a rich history dating back to the 1600s and has evolved significantly, especially in treating decompression sickness and other medical conditions.

Hyperbaric oxygen therapy operates by enhancing oxygen delivery to tissues, which aids in recovery from ischemia and stimulates vital physiological processes like angiogenesis.

History and Evolution of Hyperbaric Medicine

Hyperbaric medicine has a rich history that dates back to the 1600s when physicians utilized mildly pressurized environments to treat injuries. The modern approach emerged in the 19th century during the construction of bridges, which involved caisson technology, leading to the identification of decompression sickness, known as 'the bends.' Significant advances occurred in the 20th century as institutions like Harvard began using hyperbaric oxygen in surgical procedures, leading to a growing body of research in the 1960s through the 1980s, establishing its efficacy in treating various medical conditions. Despite its beneficial developments, hyperbaric medicine has faced skepticism due to instances of unsubstantiated treatments and a general perception that it is a treatment searching for specific diseases.

In this episode, we dive into the fascinating world of Hyperbaric medicine with Dr. Jeff Kerrie, a Hyperbaric specialist from British Columbia, Canada.

Dr. Kerrie takes us through the science, history, and practical applications of Hyperbaric oxygen therapy (HBOT) as we explore the approved indications, physiological effects, and logistics of managing hyperbaric chambers.

Episode Chapters:

Introduction

Meet Dr. Jeff Kerrie and learn about his journey in hyperbaric medicine and the unique setup of Vancouver Island’s hyperbaric program.

History of Hyperbaric Medicine

A look at the origins of hyperbaric therapy, from 1600s pressurized chambers to its modern evolution.

The Physiology of HBOT

Understanding the effects of supra-physiologic oxygen pressures on microcirculation, angiogenesis, and inflammation.

Indications and Evidence:

Decompression Sickness

The mechanisms of treating “the bends” and why HBOT works so effectively.

Air or Gas Embolism

Insights into diagnosing and treating air embolism, including critical resuscitation tips.

Carbon Monoxide Poisoning

How HBOT prevents long-term neurological damage, with considerations for pregnant patients and associated toxins like cyanide.

Necrotizing Soft Tissue Infections

The role of HBOT in treating Fournier’s gangrene and clostridial infections alongside surgery.

Crush Injuries and Anemia

Exploring HBOT’s utility in tissue salvage and sustaining oxygenation in severe anemia.

Newer Indications: Sudden Hearing and Vision Loss

The emerging role of HBOT in sudden sensorineural hearing loss and central retinal artery occlusion.

Risks and Safety in the Chamber

Barotrauma, oxygen toxicity, fire safety, and managing emergencies during dives.

Logistics of Hyperbaric Medicine

A behind-the-scenes look at hyperbaric chamber setups, patient care protocols, and equipment considerations.

Closing Thoughts

Dr. Kerrie’s perspective on the future of hyperbaric medicine and ongoing research opportunities.

Key Indications for HBOT:

1. Decompression sickness ("The Bends")

2. Air or gas embolism

3. Carbon monoxide poisoning

4. Necrotizing soft tissue infections

5. Crush injuries and compartment syndromes

6. Severe anemia (e.g., in patients unable to receive transfusions)

7. Radiation tissue injury (e.g., osteoradionecrosis)

8. Sudden sensorineural hearing loss
