A novel technique for learning to intubate with the lightwand.

Editor, To achieve extended anaesthesia and analgesia, a psoas compartment–sciatic nerve block (PCSNB) requires administration of large volumes of potentially cardiotoxic local anaesthetics. Due to the anatomic location of the lumbar plexus [1], mostly within muscle tissue, initial absorption of the administered local anaesthetics after a psoas compartment block could result in relatively high early plasma concentrations. This phenomenon theoretically enhances the risk of local anaesthetic toxicity of this anaesthetic technique.
