topical anaesthesia
Noun: A type of local anesthesia that causes a loss of feeling (numbness) only on a specific, limited area of the skin or a mucous membrane. This is achieved by applying an anesthetic medication directly to the surface of the body.
This term is used in medical contexts to describe a specific method of numbing a surface area without the need for an injection. It is commonly employed for minor surgical procedures, dental work, or to relieve pain from surface injuries. - The doctor used topical anaesthesia before removing the small skin lesion. - For the eye examination, topical anaesthesia was applied via drops.
- Mechanism: The anesthetic agent blocks nerve signals at the site of application, preventing pain sensation from that specific area from reaching the brain.
- Contrast with Other Types: It differs from regional or general anesthesia, which affect larger areas of the body or cause complete unconsciousness.
- Topical Anesthesia: The American English spelling, using 'z' in "anesthesia".
- Surface Anesthesia: A less common synonym.
- Topical Anesthetic (noun): The drug or agent used to produce this effect (e.g., benzocaine, lidocaine cream).
- Surface anesthesia
- Local topical anesthesia
- Topical anesthetic agent: The specific medication used.
- Topically applied anesthesia: A descriptive phrase for the method.
This term refers strictly to anesthesia achieved by surface application. It does not refer to anesthesia that is injected (like a nerve block) or inhaled (like general anesthesia). The numbness is confined to the very area where the medication is applied.
-
loss of sensation confined to the skin or mucous surfaces (as when benzocaine or Lidocaine is applied to the surface)
