NEURAXIAL BLOCKADE Meaning and
Definition
-
Neuraxial blockade refers to a medical technique used to numb or block neural pathways involved in transmitting pain signals from specific areas of the body to the brain. It is a type of regional anesthesia that involves the delivery of local anesthetic medication near the nerves of the spinal cord.
In neuraxial blockade, a needle or catheter is inserted into the spinal canal, typically at the lumbar region of the back. This allows for medication to be injected into the subarachnoid space, the area surrounding the spinal cord and cerebrospinal fluid, or into the epidural space, the region outside the dura mater membrane.
The local anesthetic used in a neuraxial blockade blocks the transmission of pain signals from the targeted area to the brain, effectively numbing the body below the injection site. This technique is commonly used in various surgical procedures, childbirth, and for management of chronic pain.
Neuraxial blockade provides several advantages over general anesthesia, such as reduced systemic medication requirements, improved pain control, fewer complications, and faster recovery times. However, it also carries potential risks and side effects, including nerve damage, infection, bleeding, and allergic reactions.
This procedure can be performed by an anesthesiologist or a skilled healthcare professional and is often tailored to meet each patient's specific needs and medical condition. Neuraxial blockade has revolutionized pain management techniques and is considered a safe and effective method for providing localized pain relief to patients.
Etymology of NEURAXIAL BLOCKADE
The word "neuraxial blockade" is a medical term used to describe a type of anesthesia or analgesia technique that involves blocking nerve impulses in the central nervous system.
The term "neuraxial" is derived from the combination of two Greek words: "neuron" meaning nerve and "axios" meaning axis or spinal cord. It refers to the area surrounding or related to the spinal cord and its nerves.
On the other hand, "blockade" is derived from the Old French word "bloc" and originally from the Middle Dutch word "blok" meaning a "log" or "wooden frame". In a medical context, it refers to the act of hindering or obstructing a normal physiological process, in this case, nerve impulses.
