AB  - Normal  body  temperature  changes  during  the  course  of  the  day  and  is  regulated  by  the  thermoregulatory  center  in  the  anterior  hypothalamus.  The  normal  temperature  at  6  AM  is  37.2°C  and  at  4  PM  is  37.7°C.  Rectal  temperatures  are  normally  higher  than  oral  temperatures  because  of  mouth  breathing.  To  obtain  core  temperature,  readings  should  be  obtained  in  the  esophagus  or  tympanic  membrane.  During  a  fever,  the  setpoint  in  the  hypothalamus  is  shifted  upward.  During  hyperthermia,  the  setpoint  is  unchanged,  but  the  rest  of  the  body  overcompensates  to  remove  heat.  At  the  other  end  of  the  spectrum,  hypothermia  is  defined  as  core  temperature  less  than  35°C.  This  chapter  discusses  the  therapeutic  and  pathologic  implications  of  hypothermia  and  hyperthermia.
