Recurrent spinal myoclonus after two episodes of spinal anesthesia at a 1-year interval -A case report-

Abstract

Spinal myoclonus is an unusual, self-limiting, adverse event that may occur during spinal anesthesia. The exact cause and underlying biochemical mechanism of spinal myoclonus remain unclear. A few cases of spinal myoclonus have been reported after administration of intrathecal bupivacaine. We report a case in which spinal myoclonus recurred after two episodes of spinal anesthesia with bupivacaine at a 1-year interval in a 35-year-old woman. The myoclonus was acute and transient. The patient recovered completely, with no neurologic sequelae.

Complete resolution of myoclonus-like involuntary movements under subarachnoid block after midazolam administration in a patient undergoing cesarean section: a case report

“…The pathophysiology of spinal myoclonus seems to involve abnormal hyperactivity of the local interneurons of the dorsal horn with loss or impairment of inhibition of suprasegmental descending pathways [ 5 , 6 ]. Furthermore, several case reports of spinal myoclonus subsequent to neuraxial anesthesia have been published [ 8 , 9 , 10 , 11 , 12 ]. According to these previous reports, the onset, duration, and recurrence of spinal myoclonus are not predictable and are not related to dose or baricity of local anesthetics or concomitant drugs used in spinal anesthesia.…”

Myoclonus-like involuntary movements following cesarean delivery epidural anesthesia

“…The causes of spinal myoclonus include tumors, infection, trauma, and degenerative disease [2]. In rare cases, spinal myoclonus has been induced by the administration of certain drugs via neuraxial routes [3][4][5]. There are few reports of spinal myoclonus following spinal anesthesia or combined spinal-epidural anesthesia, and spinal myoclonus after epidural anesthesia is extremely rare [6].…”

“…Spinal myoclonus is a rare complication of spinal or epidural anesthesia. It is frequently encountered with the trauma, tumor, infection, or vasculopathy of spinal cord (1). In addition, intrathecal administered local anesthetic agents, opioids, radiocontrast agents and catheters are rare causes of spinal myoclonus (2).…”
