Nerve block puncture needle anesthesia

Nerve block puncture needle injects local anesthetics around the nerve stem from the ganglion, and the impulse conduction of the blocker makes the innervated area produce anesthetic effect, which 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.

During the operation, it is necessary to be familiar with the local anatomy and understand the main tissues through which the puncture needle goes as well as the nearby blood vessels, organs and body cavities, etc. The commonly used nerve tissues include the internal shoulder, the hipster, the sciatic bone, the plasmic nerve stem, the static plexus, the brachial plexus, the nerve tissue and the new ganglion or sympathetic ganglion block for diagnosis and treatment.

The indication of nerve block puncture needle depends on the scope of surgery, the time of surgery, the patient's mental state and the degree of cooperation. As long as the block area and time can meet the requirements of surgery, nerve block can be used alone or as an auxiliary means. Children with contraindications or uncooperative patients have infection, tumor, severe deformity and anesthetic allergy at the puncture site.
