block anaesthesia
Học thuậtThân thiện
Definition
Noun: * A type of regional anesthesia that numbs a specific, limited area of the body by applying an anesthetic agent directly to a nerve or bundle of nerves (nerve block). This prevents the nerves in that area from sending pain signals to the brain.
Usage
- Medical Procedure: This term is used in medical contexts to describe an anesthetic technique for surgery or pain management in a confined region, rather than rendering the entire patient unconscious.
- The dentist used a block anaesthesia to numb my lower jaw before extracting the tooth.
- For the minor surgery on his finger, the doctor recommended a block anaesthesia instead of general anesthesia.
Advanced Usage
- Specificity: The effectiveness of a block anaesthesia is highly dependent on the precise application of the anesthetic to the correct nerve pathway.
- Duration: The duration of numbness varies based on the type and amount of anesthetic agent used.
Variants and Related Words
- Conduction Anaesthesia: A more technical synonym for block anaesthesia, emphasizing the interruption of nerve signal conduction.
- Nerve Block: A common, less formal term for the same procedure.
- Regional Anaesthesia: The broader category of anesthesia that numbs a larger part of the body, which includes techniques like spinal and epidural blocks, as well as block anaesthesia.
Synonyms

Antonyms
- General Anaesthesia (anesthesia that induces a state of controlled unconsciousness)
- Local Anaesthesia (typically refers to superficial numbing of a very small area, often by topical application or direct infiltration, rather than targeting a specific nerve trunk)
