Spinal myoclonus observed following regional anesthesia is considered a rare complication. Pathophysiology is not clear, the inhibition loss in suprasegmental descending pathways and local posterior horn interneurons, hyperactivity of anterior horn neurons, and abnormal stimulation of axons in this region may be the cause of myoclonus 3-5
. Spinal or epidural anesthesia may lead to myoclonus due to neural injuries 6,7
. For myoclonus formation following local anesthetic, it has been reported that inhibitor effects are caused by increased irritability in alpha motor neurons or by direct neurotoxic properties 8
. Electrolyte imbalance and effect of B12 deficiency are not clear. In our case, myoclonus was terminated after cessation of the drug. In many cases different treatment options were considered. Drugs such as clonazepam, sodium valproate, piracetam, fluoxetine and primidon have been used 9
. In many cases, midazolam and clonazepam were the preferred drugs 2
. We administered midazolam and we observed that it was effective.
In conclusion, it should be kept in mind that spinal myoclonus, which is a rare complication of regional anesthesia, can be seen after spinal anesthesia. An anesthesiology and reanimation specialist should be careful for unpredictable postoperative complications
