简要总结
Here's a concise summary in English without the numbers:
Hypothermia is defined as a core temperature below 35°C and occurs when the body loses more heat than it produces. It is classified by severity: mild (32-35°C), moderate (28-32°C), and severe (<28°C). Trauma patients are particularly vulnerable, as hypothermia can affect cardiac, pulmonary, neurological, and coagulation systems, contributing to the "lethal triad" of metabolic acidosis, coagulopathy, and hypothermia, which increases early mortality risk.
Shivering, a key sign of hypothermia, significantly raises oxygen consumption, making its prevention during prehospital care critical. Passive warming measures, such as insulating survival blankets, are commonly used to prevent heat loss in emergencies. These blankets help maintain body temperature, protecting victims from cold and wind. Hypothermia prevalence among trauma patients on hospital arrival is high, emphasizing the importance of prehospital measures to limit its impact. However, active warming systems are often impractical in prehospital settings, leaving passive methods as the primary strategy.
详细描述
Hypothermia is defi ned as a core temperature below 35°C. Accidental hypothermia occurs when the human body loses more heat than it produces, resulting in a drop in body temperature.
Core body temperature is the standard physiological parameter for diagnosing and classifying the severity of hypothermia. Mild accidental hypothermia is defi ned as a core body temperature between 32 and 35°C, moderate hypothermia as a core temperature between 28 and 32°C, and severe hypothermia as a core temperature <28°C.
Trauma patients are at high risk of accidental hypothermia (body temperature ≤ 35°C). Hypothermia has signifi cant consequences on human physiology, including the cardiac, pulmonary, neurological, and hemostatic systems.
Hypothermia is of particular concern in trauma patients because it is associated with increased morbidity and mortality. In addition, hypothermia can infl uence blood coagulation by reducing platelet aggregation and increasing fi brinolysis. Three closely related elements: metabolic acidosis, coagulopathy, and hypothermia constitute the "lethal triad" of trauma. The presence of one or more of these elements during the management of a severely traumatized patient increases the risk of early mortality.
The occurrence of shivering in a patient is also an indicator of hypothermia. Shivering can increase oxygen consumption of muscle cells by up to 400%. The goal of prehospital care is to prevent the onset of shivering, making the use of passive warming measures crucial.

结局指标
主要结局
Statistical distribution of the temperature evolution
时间窗: From the intervention of the medical team on site until discharge from the hospital (1 month maximum)
The statistical distribution of the temperature evolution will be tested to verify whether it follows a normal distribution. The Shapiro-Wilk test and graphical methods will be used to assess this normality.
