This study examined the effects of peripheral nerve block with high-concentration tetracaine for the management of trigeminal neuralgia, and evaluated sensory function by measuring the postblock current perception threshold. ⋯ Peripheral nerve block with high-concentration tetracaine is a relatively safe and useful technique in the management of trigeminal neuralgia, particularly among older patients and those with systemic problems.

To increase awareness of the possibility of opioid induced movement disorders. ⋯ After failing many attempts at control, the authors were able to provide their patient significant pain relief from her complex regional pain syndrome type I using methadone. Unfortunately, the patient eventually developed a movement disorder, characterized by tremor, choreiform movements, and a gait abnormality, probably related to this opioid. The authors conclude that, while this type of movement disorder is uncommon, clinicians need to be aware of opioid-induced movement disorders, because they are disturbing to patients and often easily treated.
