Sympathetic Blocks

A sympathetic nerve block is a specialized procedure performed to determine if there’s damage to the sympathetic nerve chain, which extends the entire length of the spine. These nerves are responsible for managing involuntary functions of the body, such as the dilation and constriction of blood vessels.

The Structure and Function of Sympathetic Nerves

The sympathetic nerves lie on the front surface of the spinal column, outside the spinal canal where the nerves from the central nervous system reside. As part of the autonomic nervous system, they control fundamental functions that people don’t consciously think about or have direct control over.

The autonomic nervous system interacts with the central nervous system, and sometimes, arm or leg pain may result from a malfunction of the autonomic system due to injury or other underlying causes.

How a Sympathetic Nerve Block Works

A sympathetic nerve block involves injecting medication, typically an anesthetic, around the sympathetic nerves in either the lumbar region (back) or cervical area (neck). The objective of this blockage is to temporarily interrupt the sympathetic nerve system, with the hope of reducing or even eliminating pain.

Here’s how the process typically unfolds:

1. Identifying the Area: The specific region of the sympathetic nerves is located, depending on the source of the pain.
2. Administering the Injection: A targeted injection is applied to the identified area, surrounding the sympathetic nerves.
3. Evaluating the Effect: The patient’s response to the block is observed. If the initial block is effective in providing relief, additional blocks may be administered.
4. Repeating if Necessary: Depending on the patient’s response, the procedure may be repeated until the pain diminishes or is completely alleviated.

Conclusion

The sympathetic nerve block procedure is a valuable diagnostic and therapeutic tool, especially when dealing with pain that might be connected to the autonomic nervous system. By carefully targeting the sympathetic nerves, it offers a tailored approach to pain management. Whether in the lumbar or cervical regions, this minimally invasive technique can provide essential insights into underlying issues and offer substantial relief for chronic pain sufferers. Its success in initial trials often leads to repeated procedures that cumulatively contribute to lasting pain management.
