Case ReportsCircumcision supplemented by dorsal penile nerve block with 0.75% ropivacaine: a complication.
Dorsal penile nerve block is a common procedure and can provide effective analgesia after penile surgery. Ischemic complications are rare and generally result from trauma or inadvertent administration of vasoconstrictive solutions. ⋯ Theoretical concerns over the vasoconstrictive properties of ropivacaine may be sufficient to avoid its use where the potential for ischemia to end organs is present.

Case ReportsComputed tomography-guided pudendal nerve block. A new diagnostic approach to long-term anoperineal pain: a report of two cases.
To show the value of computed tomography (CT) in selectively blocking the pudendal nerve in patients with long-term anogenital pain of uncertain etiology. We report a technique to selectively block the pudendal nerve using CT guidance in 2 patients with long-term anogenital pain. ⋯ The use of CT to guide the procedure allowed precision in performing the procedure and in making a differential diagnosis.

This is a prospective study of patients referred to a tertiary care center with permanent alteration in sensation of the inferior alveolar nerves, lingual nerves or both that could have resulted only from an inferior alveolar nerve block. ⋯ Permanent nerve damage can very occasionally occur as a result of an inferior alveolar nerve block. The exact mechanism is unknown, and there is no means of prevention. Knowledge of the risks and complications of local anesthesia is essential.

Clinical Trial
[Cervical echomyography in cervical dystonia and its application to the monitoring for muscle afferent block (MAB)].
Muscle afferent block (MAB) is an intramuscular injection of 0.5% lidocaine and pure ethanol with a volume ratio of 10:1, introduced as an alternative to botulinum toxin injection for focal dystonia and spasticity. As in the case of botulinum toxin injection, the precise localization of target muscles is crucial to obtain the maximal effect from MAB. For this purpose, we performed ultrasonography of cervical muscles (echomyography) in 20 patients with cervical dystonia (11 men, 9 women; mean age 46.1), with ultrasonograph SSD-5500 (Aloca Co. ⋯ On the other hand, the movement stopped only temporarily after the injection of saline or lidocaine only. In 3 out of 16 patients, some of the uninjected synergists were activated as if to substitute for the treated muscle just after the injection. We conclude that cervical echomyography is useful to investigate the pattern of muscle activity in cervical dystonia and to accurately localize the contracting muscles during MAB.
