conduction anesthesia
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.
