Epileptic seizure during anaesthesia induction with etomidate

In this report a 20-year-old male patient who had suffered tonic-clonic seizure after a single induction dose of etomidate until a bispectral index value of 60 is presented. Our best knowledge, this case is the first report of pure etomidate [with induction dose] induced generalized tonic clonic seizure proven with EEG. Anaesthesiologists should be careful against such a complication even in the induction stage of anaesthesia during etomidate use
