Comparative StudyDo standard monitoring sites affect true brain temperature when hyperthermia is rapidly induced and reversed.
Accurate measurements of brain and core temperatures during warming and cooling of the whole organism, accidentally or therapeutically, are important for studies of thermoregulation and cerebral insults and resuscitation. ⋯ In normal dogs and monkeys, rectal, esophageal and nasopharyngeal temperatures are almost identical with brain temperatures; but during rapid external warming or cooling, brain temperature is reflected in nasopharyngeal temperature, somewhat in higher esophageal temperature, but not in even higher rectal temperature. For clinical monitoring during temperature changes, one should use primarily esophageal temperature and, if feasible, brain (epidural) temperature as well.
