AB Intraosseous  (IO)  infusion  is  the  infusion  of  fluids  or  medications  into  the  bone  marrow  cavity  of  a  large  bone.  It  is  used  for  emergency  vascular  access  (fluids  and  medications)  when  other  access  methods  have  been  attempted  and  cannot  be  quickly  established  or  have  failed.  In  neonates  during  resuscitation,  it  is  difficult  to  give  medications  through  a  peripheral  vein  because  of  insufficient  perfusion.  The  bone  medullary  cavity  does  not  collapse  during  circulatory  failure  or  hypovolemia.  Some  recommend  IO  access  if  venous  access  is  not  established  within  3  attempts  or  within  90  seconds.  The  umbilical  vein  is  the  preferred  route  in  the  delivery  room  in  a  hospital  setting,  but  IO  access  can  be  considered  if  rapid  intravenous  (IV)  access  is  essential  and  the  operator  is  not  experienced  in  umbilical  vein  catheter  placement.  IO  access  is  an  acceptable  alternative  in  prehospital  settings  and  emergency  rooms.  IO  infusion  of  medications  and  fluids  has  the  same  hemodynamic  effect  as  medications  and  fluids  infused  by  the  IV  route.
