AB Venous  access  for  blood  sampling,  hemodialysis,  hydration,  medication  administration,  and  nutritional  support  is  essential  for  the  management  of  many  chronic  diseases.1,2  A  variety  of  indwelling  central  venous  access  devices  have  been  developed  to  avoid  frequent  venipunctures  and  permit  direct  access  to  the  central  circulation.  Approximately  150  million  intravascular  devices  are  currently  in  use  in  the  United  States.3  These  devices  may  be  partially  or  completely  embedded  under  the  patient’s  skin  (Figures  66-1  and  66-2).  The  Emergency  Physician  must  be  able  to  access  these  devices  to  administer  medications  and  withdraw  blood  samples  without  causing  catheter  damage  or  catheter  thrombosis.  Familiarity  with  this  process  can  be  potentially  lifesaving  if  the  need  for  resuscitation  becomes  imminent  in  a  patient  with  an  indwelling  line.  The  necessary  procedures  for  successfully  accessing  indwelling  devices  are  described  in  this  chapter.
