“…Depocas, Hart & Heroux (1957) have shown that rats adapt their rate of heat production to changes in T. very rapidly, within 3 min, and the exposure times were long enough to allow the development of a steady intensity of shivering. Longer exposure times could not be used because in the injured rats the lower environmental temperatures caused a rapid fall in T, and if the exposure times had been extended, levels would have been reached which would have interfered with the shivering (Hemingway, 1963). The humidity of the air in the box could not be controlled and the relative humidity measured with a hair hygrometer (Townson & Mercer, Ltd) varied from about 20 % at 300 C to 60% at 00 C.…”

SUMMARY1. Shivering in response to changes in ambient or core temperature has been measured in control rats and rats injured by bilateral hind-limb ischaemia, both with and without fur.2. Removal of the fur increased the threshold ambient temperature for the onset of shivering.3. This threshold was lower than in uninjured controls during the latter half of a 4 hr period of bilateral hind-limb ischaemia in rats with or without fur.4. The threshold was also lower than in uninjured controls after the period of bilateral hind-limb ischaemia but was not significantly different from that during the period of ischaemia.5. The alterations in threshold were not accompanied by any significant changes in the slope of the regression line relating intensity of shivering and ambient temperature.6. When the core temperature fell after limb ischaemia to levels which provoked shivering in uninjured controls, no shivering was seen in the injured rats.7. These results are interpreted as further evidence for the lowering of the 'set-point' for thermogenesis after injury in the rat and are discussed in relation to the changes in body temperature after injury in that species.

“…It increases left ventricular afterload, indicating increased myocardial work and oxygen demand which could result in myocardial ischaemia [3,4]. It induces shivering which has been shown to increase the oxygen consumption by as much as 500% [5]. This could be associated with post operative instabil-ity and prolonged recovery [3,6].…”

Background: Transurethral resection of the prostate gland with irrigation fluid at room temperature leads to perioperative hypothermia which could give rise to adverse cardiovascular events in the perioperative period. The use of isothermic irrigation fluid reduces but does not eliminate this risk. Routine use of warm intravenous fluids along with isothermic irrigation had not been documented. This study set out to investigate the effect of the use of warm intravenous fluid together with isothermic irrigation fluid on the body temperature in patients undergoing transurethral resection of the prostate gland.

“…Shivering activated during cold stimulation 24 is a natural physiological response to an altered hypothalamic set point. 19 As body temperature decreases to less than the set point of 36ºC to 37ºC, efferent signals cross the median forebrain bundle, which terminates in the hypothalamus, communicate downward to the reticulospinal neurons in the lower part of the brain stem, and activate shivering.…”

“…24,25 Shivering is an involuntary, rhythmic tremor of skeletal muscle groups that consists of oscillatory movement. 22 Early experiments 24 revealed that a mild shivering reaction can be elicited within minutes and can progress to severe shivering, involving generalized movement of all muscle groups. Shivering typically increases the basal metabolic rate to a value 2 to 5 times greater than the normal rate.…”

Therapeutic temperature modulation, which incorporates mild hypothermia and maintenance of normothermia, is being used to manage patients resuscitated after cardiac arrest. Methods of modulating temperature include intravenous infusion of cold fluids and surface or endovascular cooling. During this therapy, the shiver response is activated as a defense mechanism in response to an altered set-point temperature and causes metabolic and hemodynamic stress for patients. Recognition of shivering according to objective and subjective assessments is vital for early detection of the condition. Once shivering is detected, treatment is imperative to avoid deleterious effects. The Bedside Shivering Assessment Scale can be used to determine the efficacy of interventions intended to blunt thermoregulatory defenses and can provide continual evaluation of patients’ responses to the interventions. Nurses’ knowledge and understanding of the harmful effects of shivering are important to effect care and prevent injury associated with uncontrolled shivering.
