Drugs are generally withheld until core temperature is >30°C, as accumulation may occur while cold, with resultant toxicity when rewarmed. Never diagnose death and thus stop resuscitation until the patient is rewarmed to at least 32°C or cannot be rewarmed despite active measures. ...
a decline in the serum potassium level is often noted in hypothermic individuals. However, many patients manifest hyperkalemia as hypothermia progresses in the presence of worsening acidosis or comorbid conditions such as renal failure, rhabdomyolysis, or, as may occur in avalanche victims, crush inju...
rewarming is essential to allow return of cardiac function.36,37Hypothermia can also play a major role in facilitating aspiration in immersion victims. As the core temperature drops below 35° C, muscular incoordination andweaknessoccur, and this can interfere with swimming. As the core temperature...
In peacetime, people rarely suffer the severe consequences of cold injury when going about their everyday lives.Those incidents that do occur are usually a result of a natural disaster that destroys housing and infrastructure such as an earthquake. Accidents occur of course and people or vehicles ...
Paradoxical undressing may occur, where the victim sheds their clothes As the victim gets colder, shivering stops Severe hypothermiacore temperature below 28°C (82°F) Coma Dilated pupils, loss of reflexes Decreased blood pressure Decreased heart rate ...
occur over a number of weeks. The degree to which a person reacts to a cold air stress is dependent on such factors as age, physical stamina, the intensity of the cold stress, and the responsiveness of the thermoregulatory system. One of the most convenient ways to determine whether ...
Evaporation (25%)—heat is lost as a result of the latent heat of vaporisation, when heat from the body is used to turn a liquid into a gas. Examples include sweating or evaporation from exposed body cavities or mucosal surfaces, skin preparation fluids, and the humidification of any dry ...
develop mild hypothermia after extended exposure to indoor temperatures that would naturally be fine for a healthier or younger adult. This can occur in a home that is poorly heated or in a home that has air-conditioned. Signs and symptoms of this kind of hypothermia may not be as apparent....
We propose that: a) posttraumatic neurotransmitter and ischemic hypersensitivity occur as the result of impaired glutamate receptor- effector downregulation secondary to aberrant protein kinase activation, especially by PKC; b) a therapeutic reduction of posttraumatic neurotransmitter and ischemic ...
