AB Regional  nerve  and  plexus  blocks  have  been  integral  to  the  practice  of  anesthesiology  for  over  60  years  and  are  commonly  used  for  hand,  arm,  hip,  knee,  and  foot  surgery.  Initially,  training  in  regional  anesthesia  relied  on  identification  of  anatomic  landmarks  and  the  perception  of  various  clicks  and  pops  as  fascial  planes  were  traversed  by  a  blunt-tipped  needle.  Several  decades  later,  nerve  stimulators  were  incorporated  into  the  block  procedure  to  assist  with  more  precise  placement  of  the  anesthetic  delivery  needle  as  close  to  the  target  nerve  or  nerve  plexus  as  possible.  The  success  of  these  regional  anesthetic  blocks  was  highly  operator  dependent,  however,  and  even  with  the  use  of  a  nerve  stimulator  in  skilled  hands,  block  failure  rates  of  10–30%  were  not  uncommon,  depending  on  the  site  of  the  block.1,2
