What is another term for a local anesthetic block?

Regional anesthesia is the correct term for a local anesthetic block because it refers to the technique of anesthetizing a specific region of the body by injecting a local anesthetic around nerves that supply sensation to that area. This method effectively blocks sensation in a larger area than just a single injection site, making it suitable for procedures involving specific regions, such as limbs or the lower half of the body.

Local anesthetic blocks are often categorized under regional anesthesia since they involve a larger anatomical area and can include various techniques such as nerve blocks, epidurals, or brachial plexus blocks. This is distinct from spinal anesthesia, which specifically targets the spinal canal, and general anesthesia, which induces a state of unconsciousness, or topical anesthesia, which numbs only the surface of the tissue.
