How Does Nerve Block Therapy Work

Opinions and suggestions: block the brain nerve, spinal nerve and its ganglion with local anesthetic, or sympathetic ganglion, through nerve block to relieve pain, improve blood circulation, the purpose of treating painful diseases, called nerve block therapy. Although nerve block therapy is performed in much the same way as nerve block, depending on the purpose, the drug used and its concentration may vary, and the position in which it is performed may vary. The mechanisms of nerve block therapy are as follows :(1) blocking the nerve conduction pathway of pain; (2) Blocking the vicious circle of pain: clinically, it was observed that the analgesic time produced by local anesthetic nerve block was significantly longer than the anesthetic time of local anesthetic itself; In some patients with pain that persists for several years and fails to respond to multiple treatments, a single nerve block is able to relieve the pain, suggesting that blocking local nerve pathways is not the only mechanism of action for the use of local anesthetics to treat pain. This is thought to be due to nerve block therapy cutting off the cycle of pain ® muscle tension or spasm of smooth muscle in small vessels ® pain intensification. (3) Improve blood circulation: Sympathetic block can improve blood flow in the area it insupplies, thus effectively improving the pain caused by poor peripheral blood circulation. (4) Anti-inflammatory effect: Studies have confirmed that nerve block therapy, especially sympathetic nerve block therapy, has anti-inflammatory effect and thus produces good analgesic effect.
