Lumbar Sympathetic Block
A lumbar sympathetic block is an injection of local anesthetic into or around the sympathetic nerves. These sympathetic nerves are a part of the sympathetic nervous system. The nerves are located on the either side of spine, in the lower back. Normally these nerves control basic functions like regulating blood flow. In certain conditions, these sympathetic nerves can carry pain information from the peripheral tissues back to the spinal cord.
A lumbar sympathetic block is performed to block the sympathetic nerves that go to the leg on the same side as the injection. This may in turn reduce pain, swelling, color, sweating and other unusual changes in the lower extremity and may improve mobility. It is done as a part of the treatment of Reflex Sympathetic Dystrophy (RSD), Sympathetic Maintained Pain, Complex Regional Pain Syndrome and Herpes Zoster (shingles) involving the legs. Certain patients with neuropathy or peripheral vascular disease may also benefit from lumbar sympathetic blocks.
It is done with the patient lying on their stomach. The patients are monitored with EKG, blood pressure cuff and an oxygen-monitoring device. Temperature sensing probes may also be placed on your feet. The lumbar sympathetic block is performed under sterile conditions. The skin on the back is cleaned with antiseptic solution and the skin is then numbed with a local anesthetic. Then X-ray is used to guide the needle or needles into the proper position along the outside of the spine. Once in place, a test dose of dye is used to confirm that the injected medication will spread in an appropriate area. If this is okay, the injection takes place gradually over several minutes. The physician will use the X-ray to evaluate the spread of the injected medication. When a sufficient area is covered, the injection will be over. When done, the needle is removed and a Band Aid is applied.
