Lumbar Hemp Needle And Epidural Anaesthesia Distinction

There are three layers of spinal membrane in the spinal cavity, which are the dural, arachnoid and pia mater. The space between the vertebral periosteum and the dura is the epidural space. Between the arachnoid membrane covering the spinal cord is the subarachnoid space.

Lumbar anesthesia is also called subarachnoid block anesthesia and is administered in the subarachnoid space. This lacunae contains cerebrospinal fluid and spinal cord, so the amount of drug is relatively small, and the place of block is below the anesthetic plane, which is usually called lower body anesthesia, and the sensation and movement below the anesthetic plane are blocked.

Epidural block anesthesia is in epidural space, the lacuna is loose connective tissue, blood vessels and lymphatic vessels, etc., through the epidural space can block the spinal nerve root, spread of segmental block, which is according to the dosing interval, block one or a few spinal cord segmental dominance within the plane of sensory and motor nerve. Postoperative patient-controlled analgesia (PCA) is usually performed by epidural catheterization.

Because adults often scattered in lumbar spinal cord segment below 1 horsetail suspending in the cerebrospinal fluid, puncture is not easy to damage of spinal cord, so the waist hemp is usually applied to 1 below the waist, lumbar hemp and is suitable for the operation, applies to epidural, and because of epidural and intracranial don't are interlinked, so in theory is applicable to any operation other than the cerebral surgery, In practice, however, it is usually performed below the chest, and high level epidural anesthesia requires more skill and carries a greater risk of problems. Lumbar anesthesia and epidural anesthesia can be performed simultaneously, known as combined lumbar and epidural block anesthesia, providing more sustained and extensive surgical analgesia and anesthesia.
