plexus block

Last reviewed 01/2018

A plexus block entails anaesthesia of a group of nerves - motor, sensory and sympathetic - for a region of the body.

Examples include:

  • brachial plexus block:
    • can be reached via an axillary or supraclavicular approach
    • fine catheter is placed in the outer sheath of the brachial plexus and local anaesthetic is infused
    • capable of providing total anaesthesia for the upper limb
  • cervical plexus block:
    • can be achieved at several levels, e.g. injection of 10ml of local anaesthetic at the C3 vertebra will provide a deep cervical block from C1 to C4
    • can be used for anaesthesia during neck dissection
  • coeliac plexus block
