>> Radio Frequency Ablation

Introduction:
Radiofrequency ablation (or RFA) is a procedure used to reduce pain. An electrical current produced by a radio wave is used to heat up a small area of nerve tissue, thereby decreasing pain signals from that specific area.

How Are Nerve Blocks Used?
RFA can be used to help patients with chronic (long-lasting) low-back and neck pain and pain related to the degeneration of joints from arthritis.

Radiofrequency Ablation Safe?
RFA has proven to be a safe and effective way to treat some forms of pain. It also is generally well-tolerated, with very few associated complications. There is a slight risk of infection and bleeding at the insertion site. Your doctor can advise you about your particular risk.

How Do I Prepare for Radiofrequency Ablation
To prepare for radiofrequency ablation treatment, you should take a few precautions, including: *Do not eat within six hours of your appointment. You may have clear liquids until two hours before the procedure.
*If you have diabetes and use insulin, you must adjust the dosage of insulin the day of the procedure. Your primary care doctor will help you with this adjustment. Bring your diabetes medication with you so you can take it after the procedure.
*Continue to take all other medications with a small sip of water. Bring all medication with you so you can take it after the procedure. Please note: Do not discontinue any medication without first consulting with your primary or referring doctor.
*You will need to bring someone with you to drive you home after the procedure. You should not drive or operate machinery for at least 24 hours after the procedure.

What Happens During Radiofrequency Ablation?
You will meet with a doctor for an evaluation. If a radiofrequency ablation is recommended, a doctor will explain the procedure in detail, including possible complications and side effects. The doctor will also answer any questions you may have. An intravenous (IV) line may be placed in a vein in your arm before the procedure and a local anesthetic and mild sedative may be used to reduce any discomfort during RFA. You will be awake during the process to aid in properly assessing the procedure.
After the local anesthesia (you will be awake but will not feel any pain) has been administered, your doctor will insert a small needle into the general area where you are experiencing pain. Using X-ray, your doctor will guide the needle to the exact target area. A microelectrode is then inserted through the needle to begin the stimulation process. During the procedure, your doctor will ask you if you are able to feel a tingling sensation. The object of the stimulation process is to help your doctor determine if the electrode is in the optimal area for treatment. Once the needle and electrode placement are verified, a small radiofrequency current is sent through the electrode into the surrounding tissue, causing the tissue to heat. You should not feel discomfort during the heating portion of the procedure.
