Mechanism of nerve block puncture needle therapy

1. Block the nerve conduction pathway of pain.
2. Blocking the vicious cycle of pain: It has been clinically observed that the analgesic time produced by nerve block with local anesthetics is significantly longer than the anesthetic action time of local anesthetics. This is thought to be because nerve blocks cut off the vicious cycle of "pain -- increased pain caused by muscle tension or spasms of the smooth muscles of small blood vessels".
3, improve blood circulation: the implementation of sympathetic nerve block can improve the blood flow in its innervated area, so as to effectively improve 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.
