Nerve Blocks

A nerve block or neural blockade is a procedure in medicine and anesthesia whereby a specific nerve or group of nerves is prevented from transmitting signals. The term "nerve block" is often used interchangeably with "regional anesthesia".

Pronunciation

Nerve block: /nɜːrv blɒk/

Etymology

The term "nerve block" is derived from the English words "nerve", referring to the bundles of fibers in the body that transmit sensations, and "block", referring to the act of preventing something.

Types of Nerve Blocks

There are several types of nerve blocks, including:

• Epidural anesthesia
• Spinal anesthesia
• Peripheral nerve blocks
• Neurolytic blocks
• Sympathetic nerve blocks

Procedure

The procedure for a nerve block involves the injection of an anesthetic near a specific nerve or bundle of nerves. This can cause a loss of sensation in a specific area of the body, allowing medical procedures to be performed without causing pain to the patient.

Uses

Nerve blocks can be used for various purposes, including pain management, surgical anesthesia, and the diagnosis of specific medical conditions. They are often used in procedures involving the limbs, the face, the spine, and the abdomen.
