Body Cooling

Accidental hypothermia is defined as a body temperature lower than 35° C (95° F) in otherwise healthy individuals, resulting from excessive exposure to cold. Any thin person immersed in water around the British Isles for several hours, even in summer, is liable to suffer a dangerous degree of body cooling, and accidental hypothermia is the commonest cause of death after shipwreck.1 2 Hill walkers who lose their way or collapse from exhaustion may die of cold.3 Infants4 and some old people5 are particularly liable to hypothermia as they are less well able to conserve heat.

Calcium Induced Calcium Release

Abstract Background Malignant hyperthermia (MH) is a rare genetic disease characterized by the development of very serious symptoms, and hence prompt and appropriate treatment is required. However, postoperative MH is very rare, representing only 1.9% of cases as reported in the North American Malignant Hyperthermia Registry (NAMHR). We report a rare case of a patient who developed sudden postoperative hyperthermia after mastectomy, which was definitively diagnosed as MH by the calcium-induced calcium release rate (CICR) measurement test. Case presentation A 61-year-old Japanese woman with a history of stroke was hospitalized for breast cancer surgery. General anesthesia was introduced by propofol, remifentanil, and rocuronium. After intubation, anesthesia was maintained using propofol and remifentanil, and mastectomy and muscle flap reconstruction surgery was performed and completed without any major problems. After confirming her spontaneous breathing, sugammadex was administered and she was extubated. Thereafter, systemic shivering and masseter spasm appeared, and a rapid increase in body temperature (maximum: 38.9 °C) and end-tidal carbon dioxide (ETCO2) (maximum: 59 mmHg) was noted. We suspected MH and started cooling the body surface of the axilla, cervix, and body trunk, and administered chilled potassium-free fluid and dantrolene. After her body temperature dropped and her shivering improved, dantrolene administration was ended, and finally she was taken to the intensive care unit (ICU). Body cooling was continued within the target range of 36–37 °C in the ICU. No consciousness disorder, hypotension, increased serum potassium level, metabolic acidosis, or cola-colored urine was observed during her ICU stay. Subsequently, her general condition improved and she was discharged on day 12. Muscle biopsy after discharge was performed and provided a definitive diagnosis of MH. Conclusions The occurrence of MH can be life-threatening, but its frequency is very low, and genetic testing and muscle biopsy are required to confirm the diagnosis. On retrospective evaluation using the malignant hyperthermia scale, the present case was almost certainly that of a patient with MH. Prompt recognition and immediate treatment with dantrolene administration and body cooling effectively reversed a potentially fatal syndrome. This was hence a valuable case of a patient with postoperative MH that led to a confirmed diagnosis by CICR.

Whole Body Cooling

The rate of heat loss through the stretched wings (Hwings) was studied in resting pigeons preheated to a body temperature (43.7°C) within the range of those recorded during flight. The experimental system was designed to allow the calculation of Hwings from the increase in whole-body cooling rates resulting from exposure of the wings to various wind speeds (0–50 km h−1) at 23°C. The maximum value of HWings was 3.8 W, less than twice the heat production of a resting pigeon. This indicates that the contribution of the wings to heat dissipation during flight may not be nearly as important as has been supposed. At low windspeeds (0–12.5 km h−1), HWings corresponded to about 40% of the resting rate of heat production, and this value is discussed in connection with the various wing postures observed in hyperthermic birds.

The Subject

An understanding of the maintenance of normal body temperature, and the manner in which surgery, anaesthesia, and related procedures may disturb thermoregulation, is of considerable importance in paediatric anaesthesia. The subject of accidental hypothermia, with particular reference to the newborn infant, is reviewed; and hyperpyrexia is briefly discussed.

Severe Hypothermia

Accidental hypothermia is not a frequent cause of death in Australia. Moreover it is rare to have an admission to hospital with a core temperature below 32°C. Among the cases described in the literature, it is clear that temperature and prognosis are related. Our patient presented with severe accidental hypothermia and even though the admission core temperature was below 26 degrees she was successfully discharged from hospital after active re-warming with three different devices. She had laboratory and ECG findings associated with severe hypothermia.

A study at 5 C was made of body temperature and heart rate after a standard dose of sodium pentobarbital in normal, thyroidectomized, and hypermetabolic rats before and after subjection to 5 C for 46 hr. It was found that after subjection to cold in the normal rats, the body temperature and heart rate in some animals had more ability to recover after the barbiturate than in rats without previous exposure to cold. There was no ability to recover in the thyroidectomized animals either before or after subjection to cold. Most of the normal and thyroidectomized rats either with or without previous exposure to cold given sodium 3,3',5-l-triiodothyronine (T-3) had recoveries after the barbiturate. Some rats given T-3 and subjected to cold had a primary fall in temperature and heart rate that was followed by recovery and then a secondary fall.

Body Cooling

Sixteen adult cats were cooled, using the method of hypercapnia and hypoxia. Seven cats died during the cooling or warming period due to irreversible ventricular fibrillation or cardiac arrest. Nine cats survived and the lowest body temperature obtained was 12.5°C. The rate of body cooling and the oxygen and carbon dioxide concentrations were critical parameters difficult to control in a large animal such as the cat.

Parameter Monitoring

A wireless real-time detection instrument for human health status based on GSM Network is presented. It can real-time monitor the ECG, pulse rate, oxygen saturation, body temperature and other parameters of human body. It has its own characteristics in being small and easy to carry with. Since the coverage of GSM network is broad and inexpensive, the real-time monitoring data of this instrument will be sent to the hospital or ambulance station. If there are any anomalies, the automatic SMS will be sent to patient’s family members, and an emergency telephone will be dialed to win the valuable time of the rescue. The high-end products with GPS positioning function can automatically inform the specific location of the patient, and the patient can be helped in the shortest time for emergency treatment in the case of his loss of active consciousness.

Foraging Time

Radiotelemetry techniques were employed to study the relationship between activity and abdominal temperature (Tb) changes in free-ranging muskrats (Ondatra zibethicus). Body cooling accompanied foraging activity by adults in winter and juveniles in summer and was retarded by periodic withdrawal from water. Net Tb decline during winter foraging rarely exceeded 2 °C and was relatively independent of foraging time for excursions exceeding 40 min duration. In addition to periodic rewarming within feeding shelters, muskrats appeared to avoid hypothermia during under-ice excursions by elevating Tb prior to entering water. This elevation was maximal (mean increase = 1.2 °C) for excursions exceeding 40 min duration. Comparable increases were not observed in summer.
