Sequelae Of Nerve Block Injection

Nerve blocking needles are not blocking needles, there are some differences between them. The function of blocking needle is mainly in the local area, without observing the direction of nerves in the body. However, nerve block treatment is to observe the direction of nerves in the body, and then implement nerve block on related nerves to achieve the purpose of treatment.

Blocking needles are used to inject local anesthetics or glucocorticoids into the affected area to relieve local muscle spasms and eliminate inflammation. The action site is usually the local muscle, fascia, etc. Frequent use of occlusive needles may lead to local tendon damage, dark skin pigment, muscle damage, tendon breakage, and even infection. Therefore, long-term use of occlusive needles is not recommended. Nerve block is a kind of therapy, which refers to the injection of certain anesthetic drugs into the affected nerve. The drugs are usually injected into the spinal ganglion, nerve plexus or near the nerve and sympathetic ganglion to regulate the nerve and expand the blood vessels at the lesion site, so as to achieve the analgesic effect. It can be seen that nerve block is not a blocking needle, and the parts of action of the two are different.
