Hyperthermic conditions in neurosurgical patient Academic Article uri icon

abstract

  • Thermoregulation during anesthesia–general or regional–is often significantly impaired. Any shifts from a body core temperature of 36.6° c±0.2° c results in either hyperthermia or hypothermia, causing pathophysiologic reactions. Hyperthermic disorders are very dangerously and critical for patients. Hyperthermia is caused by a variety of clinical states. It is important to differentiate controlled and uncontrolled hyperthermia and evaluate the underlying cause. In this paper we discuss most frequently pathologic state, monitoring of hyperthermic disorders and adequate clinical management. Temperature control occurs by feedback mechanisms operating through the preoptic area of the hypothalamus. Heat- sensitive neurons in this area increase their rate of firing during artificial heating. Receptors in the skin, spinal cord, abdominal viscera, and central veins primarily detect cold and …
