Combined spinal and epidural anaesthesia in labouring women is associated with more pruritus if fentanyl (25 μg) is given intrathecally, than low-dose epidural analgesia. However, no difference has been found in the incidence of post dural puncture headache, requirement for epidural blood patch or maternal hypotension. [2] It is unknown if ...
Medical intervention Epidural administration A freshly inserted lumbar epidural catheter. The site has been prepared with tincture of iodine, and the dressing has not yet been applied. Depth markings may be seen along the shaft of the catheter. ICD-9-CM 03.90 MeSH OPS-301 code 8-910 [edit on Wikidata] Epidural administration (from Ancient Greek ἐπί, "upon" + dura mater) is a method of ...
A spinal anaesthetic delivers drug to the subarachnoid space and into the cerebrospinal fluid (CSF), allowing it to act on the spinal cord directly. An epidural delivers drugs outside the dura (outside CSF), and has its main effect on nerve roots leaving the dura at the level of the epidural, rather than on the spinal cord itself.
Between the vertebrae and the dural sheath is the spinal epidural space. Unlike the cranial epidural space, the spinal epidural space contains adipose tissue , the internal vertebral venous plexuses and the spinal nerve roots. [ 1 ]
Spinal and epidural are the most commonly used forms of central neuraxial blockade. Spinal anesthesia is a "one-shot" injection that provides rapid onset and profound sensory anesthesia with lower doses of anesthetic, and is usually associated with neuromuscular blockade (loss of muscle control).
Intrathecal administration is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF). It is useful in several applications, such as for spinal anesthesia, chemotherapy, or pain management. This route is also used to introduce drugs that fight ...
The spinal cord (and brain) are protected by three layers of tissue or membranes called meninges, that surround the canal. The dura mater is the outermost layer, and it forms a tough protective coating. Between the dura mater and the surrounding bone of the vertebrae is a space called the epidural space.
The outermost, protective sheath surrounding the spinal cord is called the dura mater. Between this and the surrounding vertebrae is the epidural space, filled with connective tissue, fat and blood vessels, and crossed by the spinal nerve roots. A catheter may be inserted into this space for three to six months, to deliver anesthetics or ...
