A Stellate Ganglion Block is performed as both a diagnostic and therapeutic measure for patients suffering from upper
extremity or facial pain suspected to be sympathetically mediated. This block has also been used successfully in patient
suffering from Complex Regional Pain Syndromes (CRPS) also known as RSD. Overall, Indications for stellate ganglion blocks
include reflex sympathetic dystrophy of the upper extremities, Raynaud syndrome of the upper extremities, herpes zoster of
the face or neck, hyperhidrosis of the neck of an upper extremity, and upper extremity pain due to arterial insufficiency. Pain
due to arterial insufficiency can be treated with a stellate ganglion block, but this would have no effect on someone with
venous insufficiency.
After an IV is placed in the preop area, the patient will be placed in the supine (face up) position and using the live X-ray
(fluoroscope) the correct area in the mid-lower neck will be identified. After numbing the area with local anesthetics, a small
needle will be directed towards the anatomic location of the stellate ganglion. Before injection of the local anesthetic solution,
the correct position of the needle will be confirmed by injection of contrast material.
The procedure lasts about 15-20 minutes. After the completion of the procedure, Band-Aids will be placed at the injection
sites, and a nurse will monitor the blood pressure and pulse and will review the discharge instructions with the patient before
going home.
You may experience the development of a "bloodshot" eye, hoarse voice, nasal stuffiness, difficulty swallowing, and the
sensation of warmth, or tingling in your hand. These symptoms are normal with this block and should disappear in 6 to 12
hours.
