Medically, what is the nerve block puncture needle technique?

Nerve block under anesthesia. Or chemical or certain physical factors can temporarily or permanently eliminate neurological function. Include local anaesthesia, such as the use of drugs. In fact, this is also similar to local anesthesia of the nerve area. It is also a nerve block, permanent destruction of nerve roots by chemical drugs, or even physical anesthesia. For example, complete physical cutting of nerve roots, such as thermal radiofrequency and microwave, is classified as nerve block. The main purpose of its treatment is to relieve the patient's pain, which cannot be controlled by the use of drugs.

"Nerve block" is a method of injecting an anesthetic into a single site to achieve a large area of anesthesia. However, this method is difficult to use and requires understanding the anatomy of the tissue. The purpose of this method is to reduce the pain through the anesthetic, thus reducing postoperative complications and improving the patient's recovery. Now we use ultrasound-guided nerve block to improve the safety and accuracy of nerve block. Peripheral nerve block can provide patients with satisfactory intraoperative and postoperative analgesia, which is conducive to early rehabilitation exercise for patients.

Nerve block involves injecting an anesthetic around a patient's nerve stem or plexus to block nerve transmission. It is commonly used in excision and minor surgery to relieve pain during surgery. In addition, nerve block can also treat scapulohumeral periarthritis, herpes zoster and other diseases. During the operation, it is necessary to be familiar with the local anatomy, understand the tissues to be punctured, as well as the nearby blood vessels, organs and body cavities to avoid damage.

A nerve block, in which a local anesthetic is injected into the nerve stem, plexus, and fibers to block nerve conduction, is a critical type of treatment. For the treatment of diffuse pain, postoperative relief of pain caused by cancer or childbirth pain can also be used to treat diffuse pain. For example, nerve blocks are often used in clinical medicine to treat some pain caused by periarthritis of the shoulder, trigeminal neuralgia, sciatica, and shingles. With this type of treatment, a significant reduction in performance can be achieved.
