[Generalized tonic-clonic seizure induced by propofol in a patient with epilepsy]

A 47-year-old female was scheduled for ulnar osteotomy under general anesthesia combined with brachial plexus block. She had a history of symptomatic epilepsy due to subarachnoid hemorrhage. Immediately after giving 100 mg bolus of propofol to the patient, she developed generalized convulsion similar to a grand mal. The seizure was suppressed by the administration of thiamylal. After that no further convulsive attack occurred. Although it has been known that propofol has anticonvulsive properties, there have been several reported cases of seizure following the administration of propofol. Further studies are needed to clarify the mechanism of seizure induced by propofol in the patients with epilepsy.
