What is PENS?

Prior to the Procedure

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. You will be assisted to position on the procedure table. The position you are placed in will depend on where the stimulator electrode needs to be placed.
  4. The anaesthetist will give you some sedation into your vein.
  5. The doctor will mark the area to be treated and inject local anaesthetic to numb the area before inserting one or two thin probes under your skin.
  6. You will then be wheeled into recovery where the PENS therapy will take place.
  7. You will be connected to the PENS machine which will deliver the therapy.
  8. A very low voltage electrical current is delivered through the probe/s for approximately 30-45 minutes.
  9. On completion of therapy, the probe(s) will be removed.
  10. After having something to eat and drink, you will be discharged with a carer.
