How Long Is The Nerve Block Needle Maintained At A Time

The maintenance time of nerve block is related to the site and method of the block, and also varies from person to person. For example, brachial plexus block can generally last about one month, and some patients can persist for two months.

Therapeutic nerve blocks are divided into destructive nerve blocks and local anesthetic nerve blocks. Disruptive nerve block refers to the use of high concentrations of local anesthetics or neurodestructive drugs to block nerve conduction for a long time or even permanently (irreversibly). Local anesthetic nerve block mainly uses local anesthetic drugs to block nerve conduction function. It is mostly used for pain treatment, but also can be used for surgical analgesia. The main mechanism of nerve block is to block the pain conduction pathway, block the vicious cycle of pain, improve blood circulation, nutrition nerve and anti-inflammatory. Compared with the traditional closure, the clinical effect is better and the side effect is less.

After nerve block must pay attention to rest, avoid excessive fatigue, ensure nutrition.
