131 - Hypothermia and Frostbite

Accidental hypothermia is generally manifested as progression from an initial state of catecholamine release and stimulation (mild hypothermia) to one marked by a predictable slowing of metabolism and all critical body functions to the extent that patients may appear dead. The profound physiologic changes and metabolic slowing all reverse with rapid rewarming, and reports of remarkable neurolog...

Frostbite: prevention and initial management.

Frostbite is a local freezing injury that can cause tissue loss. Historically, it has been a disease of wars, but it is a hazard for anyone who ventures outdoors in cold weather. Frozen tissue is damaged both during freezing and rewarming. Frozen tissue is numb. Rewarming causes hyperemia and is often painful. Blisters and edema develop after rewarming. Hard eschar may form with healthy tissue ...

Prediction and Prevention of Frostbite

Occurrence of frostbite: Among teenagers, the annual incidence of frostbite in Finland was 4.1% in boys and 2.4% in girls. Lifetime experience of frostbite was 44 % among men entering their military service. In Finland during the 6 to 12 month military service the prevalence of frostbite was 1.9 % and sequelae of hand frostbite were present in 63 %. Prediction of frostbite: Individual risk fact...

Frostbite: incidence and predisposing factors in mountaineers.

BACKGROUND Frostbite, the most common cold injury, occurs in mountaineers, a major group at risk, more often than in the general population. OBJECTIVES To describe the incidence of frostbite and the situations associated with it in mountaineering, emphasising factors that can be modified to decrease its frequency and severity. METHODS In this cross sectional, questionnaire based study, 637 ...
