Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural block and intrathecal block, [1] is a form of neuraxial regional anaesthesia involving the injection of a local anaesthetic or opioid into the subarachnoid space, generally through a fine needle, usually 9 cm (3.5 in) long.
Lumbar punctures may also be done to inject medications into the cerebrospinal fluid ("intrathecally"), particularly for spinal anesthesia [10] or chemotherapy. Serial lumbar punctures may be useful in temporary treatment of idiopathic intracranial hypertension (IIH). This disease is characterized by increased pressure of CSF which may cause ...
It was modified and revived in the 1990s, primarily by chiropractors, and also by osteopathic physicians; this was likely due to safer anesthesia used for conscious sedation, along with increased interest in spinal manipulation (SM). [26] In the MUA literature, spinal manipulation under anesthesia has been described as a controversial procedure.
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 D000767 OPS-301 code 8-910 [edit on Wikidata] Epidural administration (from Ancient Greek ἐπί, "upon" + dura mater) is a method ...
In adults, the spinal cord terminates around the level of the disc between L1 and L2, while in neonates it extends to L3 but can reach as low as L4. [16] Below the spinal cord there is a bundle of nerves known as the cauda equina or "horse's tail". Hence, lumbar epidural injections carry a low risk of injuring the spinal cord.
Intraosseous infusion (IO) is used in pediatric populations during anesthesia when other intravenous access, central venous catherization or venous cutdown, are difficult to use or cannot be used. When individuals are severely ill and need "rapid, efficient, and safe delivery of drugs", IO is used.
The two general types of alternative pressure therapy are sham acupressure and the use of the P6 point. A 2015 study found no significant difference between the use of either therapy in the treatment or prevention of PONV. In a review of 59 studies, both therapies significantly affected the nausea aspect, but had no significant effect on vomiting.
Spinal precautions including a cervical collar and rigid board have been shown to delay time to intubation, increase risk of aspiration, raise intracranial pressure and cause pain, agitation, and pressure ulcers. [4] [12] [7] A systematic review found cervical collar related skin ulcers from the devices in 7 to 38%. [16]
