How Does Spinal Anesthesia Cause Damage To The Cauda Equina?

Intraspinal anesthesia is the injection of anesthetic drugs into the subarachnoid space or epidural space of the spinal canal to block the nerve root, thereby anesthetizing the corresponding area innervated by the nerve root.

According to the puncture location and level, it can be divided into four categories: subarachnoid anesthesia (also known as spinal anesthesia or spinal anesthesia), epidural anesthesia, combined spinal-epidural anesthesia, and caudal anesthesia.

The cauda equina refers to the lumbosacral nerve root below the conus medullaris, which is usually located above the lower end of the second lumbar vertebra. The location of spinal anesthesia puncture is mainly from L2 to L5, so during spinal anesthesia and lumbar puncture, the puncture operation will not cause spinal cord injury. However, there is a cauda equina nerve there, so there is still a certain risk of related nerve damage (however, because the cauda equina is floating in the cerebrospinal fluid here, in most cases, it is not easy to be damaged by puncture, so subarachnoid puncture is still performed here. safest option).
