Abstract: | Conduction blockade was achieved at the brachial plexus of a dog undergoing surgery for pancarpal arthrodesis. The lidocaine/bupivacaine mixture used was the sole analgesic treatment applied during surgery and for 3 hours post-operatively. Location of the plexus brachialis was facilitated using a nerve stimulator. A low volume of lidocaine and bupivacaine (0.26 mL kg(-1)) resulted in successful blockade, which was evident from stable cardiorespiratory variables at low end-tidal (1.3-1.4%) isoflurane concentrations. Pain scoring and examination of motor and sensory function indicated adequate pain relief for 7 hours. While localization of the plexus brachialis can be performed 'blindly', electrolocation improves the success rate for less experienced anaesthetists. |
