What does a lumbar sympathetic block procedure include?
The total procedure time, beginning with patient prep and ending with recovery, is about one hour. This is an outpatient procedure, and we typically perform it at a pain clinic.
A lumbar sympathetic block procedure is completed in the following steps:
- The patient will lay face-down on the table.
- The pain management doctor will clean the injection site with an antiseptic solution.
- Then, they will inject a local anesthetic to prevent pain during the procedure. The patient may feel a pinch or slight pressure during this injection.
- Next, using x-ray guidance, the doctor will guide a needle into the proper position along the spine. A contrast dye is injected to confirm accurate placement.
- Finally, the mixture of anesthetic and pain medication is injected.
After completing the lumbar sympathetic injections, we monitor the patient for a brief period. This process ensures that there aren’t any serious side effects and that everything looks good for the patient.
What are the side effects of lumbar sympathetic injections?
There are very few risks associated with lumbar sympathetic injections. However, immediately following the procedure, patients may report weakness or numbness of the legs and lower back, a feeling of warmth at the injection site, or increased pain. These sensations are likely a result of the local anesthetic and tend to subside within a day.
More severe complications include nerve damage, infection, and bleeding. These side effects are rare. Talk to your doctor if you have any concerns about the procedure.
