Local Anaesthetic

Local Anaesthesia and Adrenaline



  • When used as part of local anaesthesia, adrenaline causes local vasoconstriction that increases duration, reduces bleeding and allows for greater volumes to be injected.
  • Don't inject lignocaine with adrenaline into the nose, ear, fingers, toes or penis as this may cause ischaemia secondary to vasoconstriction.
