title: Debilitating chronic pain syndromes after presumed intraneural injections.
abstract: This report presents seven patients with severe disability established at the time of a peripheral nerve block. In most of the cases, the injection was administered as a routine procedure by an experienced anesthesiologist. The patient histories suggest that the condition, which can be resistant to all treatment, in most cases could have been avoided if careful attention had been given to the occurrence of pain during the nerve block. It is likely that the risk of devastating iatrogenic disability can be minimized if a few basic principles are respected during the administration of peripheral nerve blocks.
