There are a few case reports describing prolonged myoclonus following propofol. A previously fit 26 year old woman presented for a left knee lateral impingement under general anesthesia as a day case. She had no personal or family history of epilepsy. Induction was smooth and anesthesia was maintained with propofol TCI, nitrous oxide 65% and oxygen 35%. 30 minutes after stopping of the propofol infusion, the patient developed involuntary movement and shivering that recurred intermittently. After drug therapy and psychotic therapy the patient was progressively stabilized. However 4 hours later the patient developed involuntary movement and myoclonus. She was admitted to the department of neurology under the diagnosis of propriospinal myoclonus. Forty days later she was discharged without long term sequelae.
