Stellate Ganglion Block

What should I expect from this procedure?

Stellate ganglion injection is an injection of local anesthetic into the Sympathetic Nervous System. The nerves are located in the neck, on either side of the voice box. The injection blocks the Sympathetic Nerves. This may in turn reduce pain, swelling, color, and sweating changes in the upper extremity and may improve mobility.

How quickly can I expect pain relief?

You may experience warmth and redness of the painful arm during and after the injection. You may experience hoarseness of the voice, redness of the eye, drooping of the eyelid and pupil constriction for four to eight hours after the injection. Pain relief may be noted immediately.

How should I prepare for the procedure?

You should eat no solid food or fluids after midnight prior to the procedure unless directed otherwise. You may take your regular medications with a small amount of water. If you are taking any blood thinners such as Coumadin, Warfarin, Plavix, or any others, these medications must be discontinued well before the procedure. The Advanced Pain Institute will direct you when to stop taking these medications.

What happens during and after the procedure?

A local skin anesthetic is given near the base of the neck on the affected side. A needle is inserted by the anesthesiologist near the transverse process of the cervical spine (usually at the cervical-6 level). A sterile tubing is attached to the needle and anesthetic medication is slowly injected through the tubing.
Will my insurance cover the procedure?
Most insurance companies currently cover facet joint injections. They are covered by Medicare and other government funded insurance plans. However, coverage may vary depending on your specific plan and policy.

What possible side effects might I see?

Possible side effects may include drowsiness, temporary numbness, weakness and soreness.

What should I do if any problems develop after I leave the hospital?

If you have continued pain, fever or leg weakness, call the Advanced Pain Institute. Please do not perform vigorous activity for one week. When you are feeling better, slowly increase your activity level.

What post procedure instructions are recommended?

You should rest for a few hours following the procedure, and use assistance if needed. You may resume light activity soon after the procedure, and resume your regular diet. Do not drive or operate machinery for at least 12 hours following the procedure.
