Local anesthesia is any technique used to induce the temporary absence of sensation, particularly pain, in one specific part of the body while the patient remains conscious, commonly used for minor surgical and dental procedures. Austrian ophthalmologist Karl Koller introduced cocaine as the first local anesthetic agent in 1884, demonstrating its use in eye surgery, a discovery that launched the development of the modern local anesthetic drugs and techniques used today. Local anesthesia is distinguished from general anesthesia, which induces unconsciousness, and from regional anesthesia, which numbs a larger area of the body by blocking a nerve or group of nerves.

Local anesthetics work primarily by reversibly blocking voltage-gated sodium channels in neuronal membranes, which prevents the initiation and propagation of action potentials along sensory nerves.
