Body temperature and anaesthesia.
The velocity of enzyme catalysed reactions increases with temperature to a maximum beyond which enzyme activity decreases because of protein denaturation. Many biological reactions have a 10 °C temperature coefficient (Qi0) of 2; that is, their rate of reaction doubles for a 10 °C temperature increase [62]. In mammals, protein denaturation begins at about 42 °C and internal temperatures at or a...
متن کاملBody temperature
Despite smaller physiological variations (circadian changes, ovulatory cycle, exercise, etc.), deep body temperature is relatively stable (depending on species) due to regulatory processes (Fig. 1). Core temperature is one of the components of milieu intérieur, similarly to other components it contributes to the stability of physiological functions. The basic physiological regulation is determi...
متن کاملBody temperature variability (Part 2): masking influences of body temperature variability and a review of body temperature variability in disease.
This is the second of a two-part review on body temperature variability. Part 1 discussed historical and modern findings on average body temperatures. It also discussed endogenous sources of temperature variability, including variations caused by site of measurement; circadian, menstrual, and annual biological rhythms; fitness; and aging. Part 2 reviews the effects of exogenous masking agents -...
متن کاملPreoperative preparation and premedication.
Preparing the paediatric patient for their operating room experience can be a complex process because of the many individuals involved.4 36 38 Preparation begins before patients have seen an anaesthetist because they will learn of their impending surgery from the surgeon. Surgical colleagues and their support staff can help to ease parents’ anxieties by assuring them that their child will recei...
متن کاملBody temperature cycles
Body temperature in mammals is homeostatically regulated around a set point, which renders it independent of large variations in environmental temperature. Hypothalamic regions, including the preoptic area, act as thermoregulatory centers that receive temperature inputs from the core body through hypothalamic receptors and from the environment through skin receptors. Thermogenic and heatdissipa...
