What Will Happen?

  1. You will be admitted to the day surgery by a nurse and you will be asked to change into a gown.
  2. The anaesthetist will speak with you and place a cannula (plastic needle) into a vein in your hand.
  3. In the procedure room, you will be assisted to position on the procedure table lying on your abdomen with a pillow under your hips and abdomen.
  4. The anaesthetist will give you some sedation into your vein.
  5. An X-ray machine will be used to determine where the doctor will place the needle for your procedure.
  6. Local anaesthetic and either Botox or steroid will be injected once correct needle placement has been established with use of X-ray contrast (Omnipaque).
  7. The procedure will take approximately 10 minutes to complete.
  8. After the procedure, you will be placed on a trolley and taken to recovery, where you will remain for approximately 1 hour.
  9. After having something to eat and drink, you will be discharged with a carer.
