5 step process:
1. Evaluate the patient: Ask the age, family history, what they are having problems with and what symptoms they currently have.
2. Surgery prep: Fiducials (screws) are put in to be markers for surgery. Usually put in a few days before. The areas are numbed with local anesthesia.
3. Surgery: Perform the brain surgery. A general anesthetic cannot be used because it can take hours to wear off and the patient needs to be aware during parts of the surgery. The scalp has many sweat glands and has to be scrubbed with betadine solution. Local anesthetic is injected. The head is scrubbed multiple more time to ensure sterilization. The surgeon does a …show more content…
Put in battery packs: The batteries are placed under the clavicle. The patient is under general anesthesia. The patient is tested first with out the batteries turned on and then with the batteries turned on.
5. Activate and set the system: the physician does more testing without the probe turned on. Then the probe is turned on. There is a noticeable difference in this patient when the batteries are turned on.
