Anesthesiologists have become increasingly involved with the management of chronic pain patients in the operating room, on the surgical floor, and in the outpatient pain facility setting (often interdisciplinary). Based upon the authors' practice of regional anesthesia, the most specific contribution to chronic pain management arguably remains the practice of diagnostic, prognostic, and therapeutic injections of the neuraxis, peripheral nerves, and the autonomic nervous system.

Case ReportsConvulsions during superior laryngeal nerve block--a case report.
Complications following local anesthesia for fiberoscope-assisted intubation are rare. We report a case with surgical condition indicating awake endotracheal intubation for general anesthesia, suffering from convulsions after receiving left superior laryngeal nerve block to facilitate the procedure. The possible cause may be accidental injection of the local anesthetic into the vertebral artery. ⋯ The central nervous system toxicity of local anesthetic depends not only on the dosage used, but also on the rate of injection, as well as the site at which it is injected. Starting from a small dose together with careful monitoring of patient's response is advised when nerve block in the neck is performed. Here, we also emphasize the importance of availability of resuscitation equipment for maintaining adequate ventilation and circulation in case of emergency.

The aim of this study was to evaluate the advantages and feasibility of hemorrhoidectomy using regional anesthesia (posterior perineal block). ⋯ Posterior perineal block allows the surgeon to perform radical hemorrhoidectomies in an overnight-stay regimen with safe and effective intraoperative and postoperative analgesia, sphincter relaxation, and low incidence of urinary retention. Experience of the surgeon combined with careful surgical handling are of great importance for success in this technique.

Randomized Controlled Trial Clinical Trial
Double blind randomized clinical trial examining the efficacy of bupivacaine suprascapular nerve blocks in frozen shoulder.
To determine whether the pain, contracture, and disability associated with idiopathic frozen shoulder are diminished by a series of 3 indirect bupivacaine suprascapular nerve blocks delivered in an ambulatory care clinic. ⋯ The use of bupivacaine suprascapular nerve blocks was effective in reducing the pain of frozen shoulder at one month. Clinical studies with a larger number of subjects and a longer study period will help determine the duration and nature of the effect of bupivacaine suprascapular nerve blocks in treating the pain, disability, and glenohumeral joint contracture of frozen shoulder.
