AB  - Temporary  thoracic  aortic  occlusion  should  be  performed  during  an  Emergency  Department  thoracotomy  for  hypovolemic  shock.  It  preserves  cerebral  and  coronary  artery  perfusion  pressure.1  The  blood  flow  to  the  viscera  below  the  cross  clamp,  however,  falls  to  less  than  10%  of  baseline  flow.2  This  can  be  advantageous  since  it  stops  distal  hemorrhage,  but  it  can  later  result  in  the  undesired  metabolic  consequences  of  acidosis,  hyperkalemia,  and  multiple  organ  system  failure.3,4  The  use  of  the  Emergency  Department  thoracotomy  is  likely  to  decrease  as  the  resuscitative  endovascular  balloon  occlusion  of  the  aorta  (REBOA)  technique  (Chapter  74)  becomes  more  established  and  available.
