AB Burn  injury  results  from  exposure  to  heat,  chemical,  or  electricity.  The  extent  of  the  injury  is  dependent  upon  temperature  and  duration  of  exposure,  as  well  as  the  vascular  supply  and  the  thickness  of  the  injured  skin.  At  the  center  of  the  exposure  there  is  an  irreversible  tissue  necrosis.  Surrounding  the  area  of  central  necrosis  is  a  zone  of  ischemia  in  which  there  is  a  reduction  in  dermal  microcirculation.  This  ischemic  zone  may  progress  to  full  necrosis  unless  the  ischemia  is  reversed.  At  the  periphery  of  the  burn  is  a  third  zone  of  hyperemia  characterized  by  a  reversible  increase  in  blood  flow.
