AB  - Deep  hypothermic  circulatory  arrest  (DHCA)  is  an  established  technique  used  during  certain  types  of  surgery  in  which  blood  flow  ceases  in  all  blood  vessels  while  the  patient’s  core  body  temperature  is  lowered  dramatically.  Its  use  was  first  reported  in  1959  in  children  undergoing  repair  of  Tetralogy  of  Fallot.  DHCA  is  necessary  for  cardiac  surgery  in  which  standard  cannulation  of  the  proximal  aorta  will  not  achieve  cerebral  perfusion.  Circulatory  arrest  enables  the  surgeon  to  operate  in  a  bloodless  field  with  improved  exposure  since  no  cannulae  or  clamps  are  necessary.  At  the  same  time,  deep  hypothermia  decreases  cerebral  metabolism  and  oxygen  consumption,  enabling  a  longer  period  to  operate  during  interrupted  cerebral  perfusion.  Since  the  brain  is  the  organ  most  susceptible  to  ischemia,  adequate  cerebral  protection  implies  that  other  vital  organ  systems  should  be  protected  as  well.
