Peripheral Nerve Block

A peripheral nerve block is an injection of local anesthetic around a particular nerve that lies outside of the spine. The local anesthetic is used to block the pain transmission from that nerve to the brain.

A peripheral nerve block is performed to identify the particular nerve that is carrying the painful signal. In addition, it may have a therapeutic value as well. Peripheral nerve blocks are performed to treat conditions that include neuralgias and neuritis, osteoarthritis, and to provide anesthesia for surgeries.
