In this lecture, Renée Farrar provides an engaging introduction to the fascinating world of polar medicine. As an experienced expedition doctor with a keen interest in cold and altitude, she shares her expertise on the recognition, prevention, and management of hypothermia, cold water immersion, and freezing injuries in the challenging environments of the Arctic and Antarctica.

Throughout the lecture, you’ll learn about the different stages of hypothermia, from mild to profound, and discover how the body responds physiologically to cold stress. She also discusses practical approaches to treating hypothermic patients in the field, including the use of the “Cold Card” assessment tool and the “burrito wrap” technique.

The lecture then delves into the four stages of cold water immersion response, emphasising the importance of rapid rescue and post-immersion care to prevent drowning and afterdrop. You’ll also learn how to differentiate between frostnip and frostbite, understand the grading of frostbite severity, and discover the field treatment of freezing injuries, including rewarming techniques and wound care.

By the end of this video, you’ll have a comprehensive understanding of the strategies for avoiding medical issues in cold environments, including the integration of cold considerations into the DR ABCDE assessment framework and the importance of providing prompt shelter and warmth to patients.

Intended Learning Outcomes

By the end of this lecture, participants should be able to:

1. Define hypothermia and describe the stages of hypothermia, from mild to profound.

2. Recognise the signs and symptoms of hypothermia and apply practical approaches to treating hypothermic patients in the field, including the use of the “Cold Card” assessment tool and the “burrito wrap” technique.

3. Describe the four stages of cold water immersion response and discuss the importance of rapid rescue and post-immersion care to prevent drowning and afterdrop.

4. Differentiate between frostnip and frostbite, and describe the grading of frostbite severity from first to fourth degree.

5. Outline the field treatment of frostbite, including rewarming techniques, wound care, and the importance of seeking expert advice and avoiding premature surgical intervention.

6. Discuss strategies for avoiding medical issues in cold environments, including the integration of cold considerations into the DR ABCDE assessment framework and the importance of providing prompt shelter and warmth to patients.
