AB The  maximum  duration  of  a  single-injection  peripheral  nerve  block  is  approximately  8–24  hours.1  Prolonging  a  peripheral  nerve  block  may  be  desirable,  and  can  be  achieved  with  a  continuous  local  anesthetic  infusion  via  a  perineural  catheter.  A  continuous  peripheral  nerve  block  (CPNB)  requires  placement  of  a  perineural  catheter  in  the  vicinity  of  a  targeted  peripheral  nerve  for  the  purpose  of  subsequently  administering  local  anesthetic.  Another  term  for  this  practice  is  perineural  local  anesthetic  infusion.  CPNBs  are  utilized  for  a  wide  variety  of  indications,  most  typically  for  anesthesia  or  analgesia  in  a  peripheral  nerve  distribution.  While  not  every  application  of  CPNB  has  been  exhaustively  validated  by  randomized  trials,  continuous  blocks  have  been  reported  for  over  20  anatomic  locations.  The  majority  of  described  applications  of  CPNBs  relate  to  the  treatment  of  perioperative  surgery-related  pain.
