There are limited clinical data suggesting that the success of peripheral nerve blockade supraclavicular brachial plexus may be higher in diabetic patients independent of other predictors of success eg, body mass index compared to nondiabetic patients. Pregnancy is frequently associated with a decrease in disease relapse, whereas the postpartum period is often associated with an increased risk of relapse. Ultimately, the decision to perform regional anesthesia should be made on an individual basis after a thorough discussion with the patient regarding the potential risks and benefits. This injury can produce acute uncontrolled hypertension with the introduction of a noxious stimulus below the level of the lesion, leading to a peripheral sympathetic response producing vasoconstriction below the injured level. Compston A, Coles A: Multiple sclerosis. Kuczkowski KM: Labor analgesia for the parturient with neurological disease: what does an obstetrician need to know? Suppression of the immune response with prolonged high-dose corticosteroids or intravenous immunoglobulin is the current treatment of choice. She completed a residency in anesthesia and critical care at the University of California, Davis in
Clin Neurophysiol. The following year was spent in mixed animal practice in Seattle, WA before moving on to advanced specialty training in anesthesiology. Risk factors or potential triggers for PSIN include malignancy, diabetes mellitus, tobacco use, systemic infection, volatile anesthetic use, and recent blood transfusion.
Peripheral nervous system disorders comprise neurological disease states that involve the cell body, axon, neuromuscular junction, and myelin sheath.
Preexisting pathology has long been reported to play a role in the development of postoperative neurologic dysfunction.

In contrast to peripheral nerve blockade, the potential risk of new or progressive neurologic deficits in MS patients after spinal anesthesia was first described in However, the avoidance of regional anesthesia within this patient population may also be due to physician and patient biases or potential medicolegal concerns. The goal of treatment is to sufficiently blunt the inflammatory response to allow for axonal regeneration. Williams BA, Murinson BB: Diabetes mellitus and subclinical neuropathy: a call for new paths in peripheral nerve block research. There is pathophysiologic evidence of abnormalities in both large and small neural blood vessels, ultimately contributing to multifocal fiber loss. Vocational implications of post-polio syndrome. In both cases, the use of higher local anesthetic concentrations may have contributed to the delayed recovery. Initial symptoms include hyperesthesia in the ulnar nerve distribution, elbow pain, and paresthesias in the ring and small fingers. These symptoms are often intermit-tent and may progress over the course of months to years. Postpolio syndrome is the most prevalent motor neuron disease in North America. Acta Neurol Psychiatr Belg ;—
As a result, diabetic peripheral nerves may be more susceptible to subsequent injury from local anesthetic toxicity or ischemic insults. Lastly, there is a correlation of low vitamin D levels with MS.

Another potential application of ultrasound technology is the ability to use the cross-sectional area of a peripheral nerve to identify a clinical or subclinical peripheral neuropathy: a diagnosis that historically would have required complex nerve conduction studies. A potentially dangerous condition that may develop in the month s after the resolution of acute spinal shock is autonomic dysreflexia AD. Toward a potential paradigm shift for the clinical care of diabetic patients requiring perineural analgesia: strategies for using the diabetic rodent model. She has since been working in private specialty practice and is a co-editor of and author of several chapters in the book, Pain Management in Veterinary Practice. Despite this evidence, the overall incidence and clinical relevance of this underlying peripheral neuropathy remains undefined in the setting of performing peripheral nerve blockade in patients with MS. In summary, patients with DPN likely have neural elements that are more sensitive to the effects of local anesthetic. Amyotrophic lateral sclerosis is a rapidly progressive disease with progressive degeneration of motor neurons that causes muscular weakness, atrophy, fasciculations, spasticity, and hyperreflexia.
Curr Opin Anaesthesiol. The degree of neurotoxicity depends on the agent used, the duration of administration, and the cumulative dose received. However, given the potential for worsening respiratory failure following general anesthesia due to the use of muscle relaxants and opioid medications, the ability to avoid airway manipulation may be considered a benefit within this high-risk patient population.
Pregnancy in Multiple Sclerosis Group. Most of this information is universal although, as a North American text, it is inevitable that some management protocols will differ from those in Europe and it is interesting to see references to drugs such as methoxyflurane, methohexital, and phenobarbital.
