Nerve Blocks (cont.)
Types of Nerve Blocks
Various areas of pain require different nerve block types. Below are a few of the available nerve blocks, followed in parentheses by some of the parts of the body for which they are used.
- Trigeminal nerve blocks (face)
- Ophthalmic nerve block (eyelids and scalp)
- Supraorbital nerve block (forehead)
- Maxillary nerve block (upper jaw)
- Sphenopalatine nerve block (nose and palate)
- Cervical epidural, thoracic epidural, and lumbar epidural block (neck and back)
- Cervical plexus block and cervical paravertebral block (shoulder and upper neck)
- Brachial plexus block, elbow block, and wrist block (shoulder/arm/hand, elbow, and wrist)
- Subarachnoid block and celiac plexus block (abdomen and pelvis)
Other Nerve Blocks
Other types of nerve blocks include:
- Sympathetic nerve block: A sympathetic nerve block is one that is performed to determine if there is damage to the sympathetic nerve chain. This is a network of nerves extending the length of the spine. These nerves control some of the involuntary functions of the body, such as opening and narrowing blood vessels.
- Stellate ganglion block:
This is a type of sympathetic nerve block performed to determine if there is damage to the sympathetic nerve chain supplying the head, neck, chest, or arms and if it is the source of pain in those areas. Although used mainly as a diagnostic block, the stellate ganglion block may provide pain relief in excess of the duration of the anesthetic.
- Facet joint block: Also known as a zygapophysial joint block, the facet joint block is performed to determine whether a facet joint is a source of pain. Facet joints are located on the back of the spine, where one vertebra slightly overlaps another. These joints guide and restrict the spines movement.
