“…The infusion of cold saline was not as effective in lowering body temperature as were waterdousing and ice application. Increasing the volume of infused saline is likely to improve cooling, but infusing a higher volume is impractical and increases the risk of pulmonary oedema (Bouchama, Dehbi & Chaves-Carballo, 2007). Rather than being used as a first-line cooling approach, IV infusion may be useful in situations of severe hyperthermia, where it could be used in combination with other cooling techniques, such as water-dousing, to cool an animal more rapidly.…”

The capture of wild animals is a stressful event which may cause a capture-induced hyperthermia, resulting in morbidity or mortality. We investigated whether various cooling techniques were effective at lowering the body temperature of hyperthermic animals. To achieve this, we implanted miniature temperature-sensitive data loggers into the abdomens of 12 blesbok (Damaliscus pygargus phillipsi ). Five animals were cooled by dousing with water of different temperatures (4°C, 17°C, 28°C) and fanning after dousing with 28°C water. Seven animals were cooled by ice-packs, a fine mist spray of 28°C water, intravenous (IV) infusion of one litre of 4°C saline solution or 28°C water-dousing. The body temperature after capture was significantly elevated to as high as 41°C to 42°C. Water-dousing interventions significantly decreased minimum body temperature but there was no difference in the minimum body temperature reached or the magnitude of cooling between the different water temperatures or by the addition of fanning. The ice-packs also lowered body temperature, whereas mist spraying did not. The use of ice packs and dousing with water between 4°C and 28°C were the most effective techniques to reduce capture-induced hyperthermia in blesbok. Water-dousing, when done appropriately, is the most practical and effective method to cool an animal with capture-induced hyperthermia.

“…Heat stroke syndrome is defined as core temperature exceeding 40°C associated with a change in mental status ranging from inappropriate behaviour or impaired judgment to delirium, epilepsy or coma [1][2][3]. In 20-65% of the cases, an acute circulatory failure (shock) is associated [1][2][3] as observed in our patient.…”

“…Body cooling should be instituted as early as possible and before transporting the victim. The gold standard for rapid body cooling is cold water and ice water immersion therapy (water temperature 2°-15°C ), preferably initiated within 10 minutes, in which case the survival rate is near 100 % [46][47][48]. Cold water immersion produces a 0.5°C lowering of body temperature in the first 3 minutes, after which the rate of body temperature decline typically accelerates.…”

Exertional heat-related illness (EHRI) is comprised of several states that afflict physically active persons when exercising during conditions of high environmental heat stress. Certain forms of EHRI may become life threatening if not treated. Exertional heat stroke (EHS), characterized by a core body temperature of >40°C and mental status changes, is the most severe form of EHRI. EHS must be treated immediately with rapid body cooling to reduce morbidity and mortality. Many EHRI cases are preventable by following heat acclimatization guidelines, modifying sports and exercise sessions during conditions of high environmental heat stress, maintaining adequate hydration, avoiding exertion in the heat when ill, and by educating sports medicine personnel, coaches, parents, and athletes on the early recognition and prevention of EHRI. Heat exhaustion, exercise-associated collapse, exercise-associated muscle cramps, exerciseassociated hyponatremia, and exertional rhabdomyolysis are also described.

Cooling and hemodynamic management in heatstroke: practical recommendations

Abstract: Introduction Although rapid cooling and management of circulatory failure are crucial to the prevention of irreversible tissue damage and death in heatstroke, the evidence supporting the optimal cooling method and hemodynamic management has yet to be established.
