With the increasing popularity of day case surgery it is important to
ensure that safe and appropriate techniques are being used. We retrosp
ectively reviewed a large series of 732 patients who underwent planned
day case hand surgery under intravenous regional anaesthesia (modifie
d Bier's block) over a 5-year period. We found a modified Bier's block
to be ideally suited to day case surgery with no deaths, minimal morb
idity and a success rate in excess of 98%.
