Body temperature regulation and anesthesia

2018
General anesthesia is the induction and maintenance of a state of unconsciousness with the absence of pain sensation. General anesthesia is accomplished by the administration of a combination of inhaled anesthetic gases and intravenous drugs. These medications eliminate behavioral thermoregulatory compensations, leaving only autonomic defenses to ...

Regulation of Body Temperature

1976
Birds, like mammals, are “homeotherms,” which means that they maintain a relatively constant deep-body temperature. Birds are also “endotherms,” a term indicating that they are able to increase their body temperature by generating a considerable amount of heat within their tissues instead of relying on heat gained directly from their surroundings ...

Body temperature regulation in the rat

Journal of Thermal Biology, 2000
In loosely-restrained adult conscious rats exposed to stepwise changes in ambient temperature (T(a)) from 25 to 5 degrees C or from 20 to 35 degrees C, we have recorded body and tail temperatures, metabolic rate (VO(2)), shivering and ventilation (V).

Regulation of Body Temperature

1992
Homeothermy is defined by the Thermal Physiology Commission of the International Union of Physiological Sciences [35] as a pattern of temperature regulation in which cyclic variation in core temperature is maintained within arbitrary limits of ±2°C despite much larger variations in ambient temperature.

Body temperature and its regulation

Anaesthesia & Intensive Care Medicine, 2005
Abstract Humans must maintain deep-body (core) temperature within narrow limits, despite large fluctuations in ambient temperature and metabolic heat production. Core temperature homeostasis is facilitated by behavioural strategies and physiological effector responses, which influence the factors that add and subtract body heat.

The Regulation of Body Temperature During Fever

Archives of Environmental Health: An International Journal, 1965
Abstract : Fever in man was studied calorimetrically to determine, first, the heat flows which cause changes in body temperature and, second, the physiological regulations which directly control these flows. Seventeen reactions induced by typhoid vaccine were observed in environments ranging in ambient temperature from 27 to 43 C.

Body temperature and its regulation

Anaesthesia & Intensive Care Medicine, 2008
Abstract Body temperature is regulated to a ‘set point’ that is determined by the hypothalamus. The precise value of this set point has a circadian rhythm and is also affected (increased) by trauma and sepsis. In thermoregulatory terms, the body is thought of as a ‘central’ compartment containing all the heat-producing viscera, contained in a cooler ‘
