Lumbar Sympathetic Plexus (Ganglion) Block
A ganglion block is an injection of local anesthetic in the sympathetic nerve tissue of the neck. The injection may contain both steroids and anesthetic and is administered to relieve the patient of localized pain.
Ganglion block procedure
An IV will be started before the procedure. The patient is placed on the procedure table on their back for a stellate ganglion (neck) block and on their stomach for a lumbar (low back) block. The skin on the neck or the skin on the low back is scrubbed using antibacterial soap. The physician numbs a small area of skin with numbing medicine. This medicine stings for several seconds. After the numbing medicine has been given time to be effective, the physician directs a very small needle to the area of the sympathetic nerves using x-ray guidance. A small amount of contrast (dye) is injected to ensure proper needle position. Then, local anesthetic is administered to achieve the sympathetic block.
What happens after the procedure?
Immediately after the procedure, the patient will be examined and will be asked to report the percentage of pain relief. The arm(s), chest wall or leg(s) may feel weak or numb for a few hours. It is a temporary response to the local anesthetic used for the block and will wear off. Other potential reactions to the blocks will be discussed at the time of the procedure. Patients may return to their normal activities on the day of the procedure. Driving is discouraged on the day of the procedure.
