Definition
- Noun:
- A type of anesthetic that causes loss of sensation only in a specific, limited area of the body: A "local anaesthetic" is a drug that blocks nerve signals in a particular region, allowing medical or dental procedures to be performed without causing general unconsciousness or pain in the patient.
Usage
- Noun:
- A "local anaesthetic" is administered via injection, spray, or topical application directly to the target site.
