Postoperative seizure-like activity following sevoflurane anesthesia.

Generalized clonic and tonic seizure-like movements were observed during emergence from anesthesia with sevoflurane in a 32-year-old man. The movements lasted 40 sec and necessitated no therapy. There were no significant effects of the incident on the cardiovascular system, such as hypotension, arrhythmia or bradycardia. No neurological abnormalities were obvious after the anesthesia. The movements may have been the result of seizure activity in the central nervous system, or myoclonus of the whole body.
