AB Inadvertent  arterial  injections  of  medications  can  be  a  source  of  great  morbidity  to  patients.  Accidental  arterial  injections  can  lead  to  cyanosis  of  the  limb,  gangrene,  and  possible  loss  of  the  extremity.  Anesthetic  medications,  specifically  benzodiazepines  and  barbiturates,  have  been  a  main  source  of  damage  in  the  past;  however,  there  is  an  increasing  number  of  medications  with  poor  sequelae  if  injected  arterially.  An  intraarterial  injection  can  be  given  at  any  time  in  any  patient;  however,  obese  patients,  patients  with  darkly  pigmented  skin,  and  those  with  thoracic  outlet  syndrome  are  at  increased  risk.  Additionally,  patients  with  arterial  catheters  in  place  for  blood  pressure  monitoring  are  also  at  increased  risk  of  accidental  injection  of  medication.
