“…Hypothermia is a major problem for the homeless [2,[17][18][19][20]. In the United States, 27 homeless people were reported to have died due to hypothermia in a study evaluating homeless deaths between 2005 and 2010 [18].…”

“…Alcohol increases the risk of hypothermia by decreasing the ability of people to decide to have adequate clothing and to be in appropriate environments for protection from cold as well as increases heat loss by dilatation of superficial veins [1,13,20,21]. The function of body heat protection is supplied through the sympathetic system.…”

“…Vasoconstriction in skin and skeletal muscles is the most important mechanism in the conservation of heat. This mechanism is abolished by alcohol intake at toxic levels [1,6,20,22]. There are also studies show that alcohol affects the hypothalamus and impairs heat regulation [23,24].…”

Introduction: In this study, it was aimed to investigate the frequency of autopsy findings and the frequency of cases decided to die due to hypothermia in Eskişehir. Materials and Method:This study is a descriptive study conducted in the 20-year period between 1997 and 2016 in Eskişehir province by retrospective examination of case files belonging to judicial qualifications. These deaths were included in the study because of the decision to die due to hypothermia. The cases were evaluated in terms of age, gender, location of the body, month in which the body was found, autopsy findings, psychiatric disease history, toxicological examination and death investigation information. Findings:It has been determined that in 20 year period, there were 16 deaths due to hypothermia in Eskişehir, Turkey. All cases were male and mean age (SD) was 62.4 ± 7.2 years. Wischnewsky ulcers occurred in 11 cases (68.8%) due to hypothermia. 9 cases (56.3%) had a history of psychiatric and neurological disease. Conclusion:Hypothermic deaths are preventable deaths and precautions should be taken to protect against hypothermia in elderly people, homeless people and those with mental illness that will affect the state of consciousness.

“…Hypothermia (core temperature ≤ 35 °C) is a frequent and life-threatening problem after mountain accidents, near-drowning, and intoxications [ 1 , 2 ], and can provoke arrhythmia, reduced cardiac contractility, and cardiac arrest [ 3 , 4 , 5 , 6 ]. The hypothermic heart may be insensitive to defibrillation when core temperature does not reach 30 °C.…”

The aim of our study is to investigate successful pre-rewarming resuscitation after hypothermic cardiac arrest (HCA). The hypothermic heart may be insensitive to defibrillation when core temperature is below 30 °C and after successful defibrillation, sinus rhythm often returns into ventricular fibrillation. Recurrent defibrillation attempts may induce myocardial injury. Discrepancy exists concerning pre-rewarming defibrillation between the guidelines of the European Resuscitation Council and American Heart Association. The International Hypothermia Registry (IHR) gathers hypothermia cases. The primary outcome was survival. Secondary outcomes were the characteristics of defibrillation, the effect of Adrenaline administration under 30 °C, and the duration of CPR. Of the 239 patients, eighty-eight were in cardiac arrest at arrival of the rescue team. Successful pre-rewarming resuscitation was obtained in 14 patients. The outcome showed: seven deaths, one vegetative state, two patients with reversible damage, and four patients with full recovery. A total of five patients had a shockable rhythm, and defibrillation was successful in four patients. The response rate to Adrenaline was reported as normal in six patients. There were no statistically significant differences in the presence of a shockable rhythm, the success of defibrillation, and the effect on Adrenaline administration between the survivors and non-survivors. Successful resuscitation in severe hypothermia is possible before active rewarming and arrival in the hospital, thus improving the chance of survival.

“…Individuals die of hypothermia because of failure of hypothalamic counter-regulatory mechanisms that initiate and maintain chemical thermogenesis and vasoconstriction [13,14]. Death likely results from a combination of events such as ventricular fibrillation or asystole, initiated or exacerbated by hypoxia, myocardial ischemia, increased circulating catecholamines and electrolyte derangements [1,9,15].…”
