“…It is important to quickly recognize the degree of hypothermia, and this can be done based on degree of consciousness, presence or absence of shivering, signs of breathing or pulse, and core temperature (Durrer et al 2003). It should be recognized that severe hypothermia can mimic death, and that it is impossible to be sure that death has occurred unless there are other obviously lethal injuries (Edwards et al 1970;Gregory et al 1972;Auerbach 1990). Every reasonable effort must be made to get a hypothermia victim to a hospital where full diagnostic and resuscitation resources are available.…”

PhD dissertation abstractBackground and objective: The objectives were to first determine incidence and contributing factors to cold-related injuries in Northern Sweden, both of those that led to hospitalisation and those that led to fatality. A further aim was to assess post-cooling hand-rewarming responses and the effects of training in a cold environment, both on fingertip rewarming and on function of the autonomic nervous system, to evaluate if there was adaptation related to prolonged occupational cold exposure. Methods: In a retrospective analysis, cases of accidental coldrelated injury with hospital admission in Northern Sweden in 2000-2007 were analysed. Cases of fatal hypothermia in the same region in 1992-2008 were analysed. A cohort of volunteers was studied before and after many months of occupational cold exposure. Subject hand-rewarming response was measured after a cold hand immersion provocation, and was categorised as slow, moderate, or normal in rewarming speed. This cold provocation and rewarming assessment was performed before and after their winter training. Heart rate variability (HRV) was analysed from the same cold provocation/recovery sequences. Results: For the 379 cases of hospitalisation for cold-related injury, annual incidences for hypothermia, frostbite, and drowning were 3.4/100,000, 1.5/100,000, and 1.0/100,000 inhabitants, respectively. Male gender was more frequent for all categories. Annual frequencies for hypothermia hospitalisations increased during the study period. Hypothermia degree and distribution of cases were 20% mild (between 32°C and 35°C), 40% moderate (31.9-28°C), and 24% severe (< 28°C), while 12% had temperatures over 35.0°C. The 207 cases of fatal hypothermia showed an annual incidence of 1.35 per 100,000 inhabitants: 72% in rural areas, 93% outdoors, and 40% found within 100 m of a building. Paradoxical undressing was documented in 30%. Ethanol was detected in femoral vein blood in 43%. Contributing comorbidity was common, including heart disease, previous stroke, dementia, psychiatric disease, alcoholism, and recent trauma.
