Brachial plexus block for upper limb surgery is the most common major peripheral nerve block technique. Local anesthetic drugs are relatively free of side effects if these agents are administered in an appropriate dosage and in the correct anatomic location. However, systemic and localized toxic reactions can occur, usually owing to accidental intravascular or intrathecal injection or to admininistration of an excessive dose. We report a case of supraclavicular brachial plexus block for carpal tunnel syndrome with a generalized seizure after local anesthetic injection. Fifteen minutes after the ropivacaine-lidocaine mixture injection, 55 year old female patient shows confusion and genealized peripheral muscle twitching. To minimize CNS toxicity, we injected thiopental sodium. The operation was completed without any events after general anesthesia. The CNS toxicity of local anesthetics is discussed.
