Please answer! what would happen if i inject lidocaine 2% epedefrine 1% directly into a vein or artery?

Injecting Lidocaine: Epedefrine (two different drugs, Epinephrine is most likely, Ephedrine (ephedrine sulfate) is less likely) combined with 2% Lidocaine would cause a very dramatic sensation of flight or fright. Heart racing, possibly skipped heart beats, probably irregular heart beats, and could very likely lead to serious cardiac injury or death. Don't do it! the medicines would get into circulation and affect you in about 30 secs.
