Mechanism of action

The procedure involves injecting local anesthetic agents into the paravertebral space, which lies lateral to the vertebral bodies and contains spinal nerve roots. This blocks sensory and motor nerve transmission in the distribution of those nerves, providing anesthesia and analgesia to the chest wall, abdomen, or other areas depending on the injection level. It is used as an alternative or adjunct to general anesthesia and systemic analgesia.
