Is Nerve Block Anesthetic Puncture Needle Local Anesthesia

Nerve block anesthesia is a type of local anesthesia, which is mainly injected around the nerve trunk, plexus and ganglia to block the conduction of the impulse and make the innervated area produce anesthetic effect, so it is called nerve block. Nerve block only needs to be injected in one place to obtain a large anesthetic area, but it may cause serious complications. Therefore, it is necessary to be familiar with the local anatomy and understand the tissues, blood vessels, organs and body cavities that the puncture needle must pass through during the operation.
