nerve block
Low FrequencySpecialist/Technical
Definition
Meaning
A medical procedure in which a local anaesthetic is injected near a specific nerve or group of nerves to prevent pain signals from reaching the brain.
The term can also be used metaphorically in non-medical contexts to describe an action that stops something from functioning or being felt, though this is rare.
Linguistics

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'block' as 'блок' in the sense of a unit or cube. The correct medical term is 'блокада нерва' (blokada nerva).
- Do not confuse with 'nerve damage' or 'pinched nerve'. A 'block' is a temporary, intentional interruption.
Common Mistakes
- Using 'nerve block' to refer to a physical object obstructing a nerve (e.g., a tumour). It is a procedure, not an object.
- Pronouncing 'block' as /bləʊk/ (like 'bloke') instead of /blɒk/ or /blɑːk/.
- Writing as one word: 'nerveblock'.

FAQ
Frequently Asked Questions
No. A nerve block only numbs a specific region of the body, and the patient is usually awake. General anaesthesia makes the patient completely unconscious.
It depends on the type of anaesthetic used, but effects typically last from a few hours to over 24 hours. Some therapeutic blocks can last much longer.
When performed by a trained professional, nerve blocks are generally very safe. Potential risks, like infection or nerve injury, are rare.
Yes. Nerve blocks are commonly used for chronic pain management (like for migraines or neuralgia), for diagnostic purposes, and in palliative care.
