The technique of paravertebral (near-vertebral) blockade involves the introduction of a certain medicinal mixture using a syringe into the affected area (where the pain is maximum) of the epidural space or near the exit of the nerve root from the spine. As a result of the introduction of a dose of drugs, the medicine quickly gets to the required area, reduces swelling around the affected nerve root, which helps to improve its nutrition./p>
This manipulation is carried out in a certain segment of the spine, which covers the area of the skin, muscles, bones and connective tissue. Due to this, the positive effect is noticeable after the first injection. The most common type of paravertebral block is the cervical and lumbosacral block.

Then the selected area for injection is treated with antiseptic drugs (a solution of iodine and ethyl alcohol is often used). After this, anesthesia is administered - using a thin needle, several injections are made to the left and right of the selected segment of the spine, in the area where the pain is localized. Then the specialist injects the drugs.
