Is The Medical Nerve Block Needle A Blocking Needle

Nerve blocking needles are not blocking needles. Nerve blocking needles are usually injected into the nerve plexus in the appropriate area to block the transmission of pain signals. The blocking needle is usually injected into the painful area to promote the elimination of local inflammation to relieve pain. Nerve block needle is often used for cervical radiculopathy and herpes zoster neuralgia, while block needle is often used for trauma and joint diseases.

A nerve block needle is used to point to the nerve plexus associated with the injury and inject a certain amount of anesthetics and steroids to block the conduction of pain. It can also anesthetize the muscles in the relevant areas, dilate the blood vessels in the lesion site, improve the local blood circulation, promote the metabolism of inflammatory factors, so as to achieve the purpose of relieving the disease.

Blocking needle refers to injecting a certain concentration of local anesthetics and glucocorticoids into local diseased areas, such as muscles, fascia, tendon sheath, ligament, bursa, etc., to relieve muscle spasm and promote the elimination of local inflammation. Occlusive therapy is characterized by direct access to the disease site and direct action on the pain site, which can play a role in relieving pain, controlling inflammation and preventing complications.

Therefore, nerve block needle is not equal to blocking needle. Compared with the two, nerve block needle involves a larger anesthetic area and requires higher technical requirements for the operator. It is often used in cervical radiculopathy, herpes zoster neuralgia, etc. The occlusive needle acts directly on the local pain site, which is suitable for trauma, strain, degenerative joint disease and so on.
