A peripheral upper limb nerve block is whereby local anaesthetic and other painkillers are injected close to main nerves in the arm. The injection numbs the arm to relieve any pain.

A patient can receive a nerve block while they are awake, with sedation, or with general anaesthetic. For operations on the upper limbs, patients may be given a nerve block as a replacement to general anaesthetic. The nerve block is also used for pain relief following an operation.

The area where the injection will be given will depend on the type of procedure. There are six areas where the injection can be administered:

  • elbow
  • forearm
  • at the side of your neck
  • near your armpit
  • collarbone
  • in your wrist
