Spinal Myoclonus – A rare complication of spinal anaesthesia

Spinal segmental myoclonus is a rare type of myoclonic disorder that may occur during spinal anaesthesia. A few cases of spinal myoclonus have been reported after administration of intrathecal bupivacaine. The exact cause and pathophysiology of spinal myoclonus is unknown. We report a case of a 28-year-old female who underwent caesarean section under spinal anaesthesia with 0.5% hyperbaric bupivacaine. Myoclonic movements appeared in the early postoperative period in the left lower limb. The myoclonus was acute and transient. The patient recovered completely without any neurological complications. After ruling out all the possible causes, spinal myoclonus diagnosis was made, and the patient was discharged on the 3rd postoperative day. Keywords: Spinal anaesthesia, Spinal myoclonus, Myoclonus
