Definition
Noun: * Regional nerve block: A type of anesthesia that numbs a specific area of the body by applying an anesthetic agent directly to a nerve or group of nerves that supply that area. It prevents the nerves from carrying pain signals to the brain.
Usage
- Conduction anesthesia is commonly used for surgeries on limbs, such as the hand, arm, foot, or leg.
- The anesthesiologist administered conduction anesthesia to the patient's brachial plexus for the arm surgery.
- Compared to general anesthesia, conduction anesthesia allows the patient to remain awake and alert during the procedure.
Examples

- For the knee arthroscopy, the surgeon preferred conduction anesthesia to facilitate a faster recovery.
- A successful conduction anesthesia blocks all sensation in the targeted limb for several hours.
Advanced Usage
- Technical Context: In medical literature, conduction anesthesia is a broad category that includes specific techniques like nerve blocks, epidural anesthesia, and spinal anesthesia, all of which involve interrupting nerve signal conduction in a localized region.
