Does the brain influence somatic responses to noxious stimuli during isoflurane anesthesia?

abstract：BACKGROUND:Initial postoperative core temperature is a physician and hospital performance measure. However, the extent to which core temperature changes during emergence from anesthesia and transport from the operating room to the postanesthesia care unit (PACU) remains unknown. Similarly, the accuracy of many noninvas...
