Case ReportsComplete brachial plexus palsy after total shoulder arthroplasty done with interscalene block anesthesia.
This report illustrates that brachial plexus palsy can result from either interscalene block or total shoulder arthroplasty. It is often impossible to determine which procedure caused the deficit; therefore, we believe the focus should be placed on treatment of the neurologic deficit. This report provides a suggested algorithm for diagnosis and treatment of postprocedure brachial plexus palsy. ⋯ Proper diagnosis and treatment of postprocedure brachial plexus palsy may improve recovery of function. Several precautions may reduce the likelihood of brachial plexus palsy following interscalene block for total shoulder arthroplasty.

Clinical TrialPlasma lidocaine, monoethylglycinexylidide, and glycinexylidide concentrations after epidural administration in geriatric patients.
The purpose of this study was to evaluate the effect of age on the pharmacokinetics of lidocaine after epidural administration. ⋯ The increase in plasma lidocaine concentration after epidural anesthesia in elderly patients was not as high as anticipated. However, the elderly patients showed longer MRTs, lower clearance, and lower ratios of MEGX/lidocaine than did the adult (middle-age) patients.

Clinical TrialEffect of high-dose lidocaine treatment on superoxide dismutase and malon dialdehyde levels in seven diabetic patients.
We report on the use of intravenous (IV) high-dose lidocaine to relieve diabetic neuropathic pain, and the technique's effects on clinical measures of lipid peroxidation. ⋯ High-dose lidocaine treatment lessens MDA levels, a marker of free-radical-mediated cell damage. This suggests that one of lidocaine's mechanism of action may be its effect on oxygen free radicals, which in turn impacts lipid peroxidation.

Case ReportsCalciphylaxis treated with neurolytic lumbar sympathetic block: case report and review of the literature.
Calciphylaxis is a painful complication of end-stage renal disease and secondary hyperparathyroidism. Calcification most commonly affects skin and soft tissue of the lower extremities resulting in excruciatingly painful skin ulcers. Treatment involves correction of hypercalcemia and hyperphosphatemia, parathyroidectomy, and supportive measures. ⋯ The neurolytic LSB provided pain relief and is a treatment modality to be considered in managing the pain associated with calciphylaxis.
