How is local anesthesia typically administered?

Local anesthesia is primarily administered via injection at the site of the procedure. This method allows the anesthetic to directly numb the targeted area where the surgery or intervention will take place, providing effective pain relief while minimizing systemic effects. By injecting the anesthetic directly into the tissues, it can diffuse quickly to block nerve signals in that localized region, thereby ensuring that the patient remains comfortable during the procedure.

Other administration methods such as inhalation, intravenous injection, or oral consumption are not standard for local anesthesia. Inhalation is typically reserved for general anesthesia, intravenous methods are often used for sedation or systemic analgesia, and oral routes are generally not effective for the immediate and localized effect required in procedures where local anesthesia is indicated.
