AB The  use  of  ultrasound  guidance  for  peripheral  nerve  blocks  in  regional  anesthesia  and  pain  management  offers  several  advantages  over  traditional  methods  including  the  paresthesia  technique  and  neural  stimulation  technique.  Studies  in  regional  anesthesia  and  pain  medicine  seem  to  indicate  that  ultrasound  guidance  can  decrease  the  time  required  to  perform  a  nerve  block  and  hasten  the  onset  of  block,  thus  potentially  improving  efficiency  between  operative  cases.  Patient  discomfort  may  also  be  reduced  as  ultrasound  decreases  the  number  of  attempted  needle  passes  while  performing  a  block.  Direct  visualization  of  neural  and  vascular  structures,  including  the  use  of  Doppler  and  visual  confirmation  of  local  anesthetic  spread  around  the  target  nerves,  could  decrease  the  risk  of  intravascular  injection,  intraneural  injection,  injury  to  the  lung,  or  other  nearby  vital  structures.
