Interscalene brachial plexus block: area of analgesia, complications and blood concentrations of local anesthetics.
In a prospective clinical study including 100 patients, the consequences of using the interscalene approach to block the brachial plexus were investigated according to the area of analgesia, complications, and blood concentrations of local anesthetics. Sufficient analgesia of the shoulder and the upper part of the arm was obtained in 98-99% of the cases, whilst the area of analgesia in the forearm and the hand was more variable. ⋯ No toxic reactions were seen. The complications were in accordance with those reported in other publications.

Stellate ganglion block for relief of pain and prevention of ophthalmic complications in trigeminal herpes zoster has been advised for many years. In a series of 27 patients, control of pain was dramatic after local anesthetic block of the stellate ganglion. ⋯ Because of the retrospective nature of this investigation, the lack of adequate numbers and the absence of controls, no conclusions on efficacy of treatment can be made. However, enough hope of success is presented to justify a controlled series in a large metropolitan area where adequate numbers of patients can be accumulated for a double-blind protocol.
