Neuraxial blockade
Neuraxial Blockade
Neuraxial blockade (pronunciation: /nʊərˈæksɪəl blɒˈkeɪd/) is a term used in anesthesia to describe the process of blocking the transmission of signals in the central nervous system.
Etymology
The term "neuraxial" is derived from the Greek words "neuron" meaning nerve and "axial" meaning axis. The term "blockade" is derived from the French word "blocade", meaning to block or obstruct.
Definition
Neuraxial blockade is a type of regional anesthesia that involves the injection of an anesthetic solution near the spinal cord and nerve roots. It is used to block pain signals from specific regions of the body, allowing surgical procedures to be performed without the patient experiencing pain.
Types of Neuraxial Blockade
There are two main types of neuraxial blockade: spinal anesthesia and epidural anesthesia.
- Spinal anesthesia involves the injection of anesthetic into the subarachnoid space, where it acts on the spinal cord directly.
- Epidural anesthesia involves the injection of anesthetic into the epidural space, where it acts on the nerve roots.
