nerve block

2) BLOCK ANESTHESIA

* * *

a method of producing anaesthesia in part of the body by blocking the passage of pain impulses in the sensory nerves supplying it. A local anaesthetic, such as lidocaine, is injected into the tissues in the region of a nerve. In this way anaesthesia can be localized, so that minor operations can be performed without the necessity of giving a general anaesthetic. A ring block is a common technique used for anaesthetizing a digit.

* * *

1. regional anesthesia achieved by making extraneural or paraneural injections of anesthetics next to the nerve whose conductivity is to be cut off. 2. neurolysis (def. 4).
