First of all, sorry for my english level, it is not my native language.

So, the question is, If you would use local anesthesia lets say on the nose/ears (a close place to the brain) and it would extend to the brain and put to sleep some part of the brain.

Would the patient be able to stay awake? or his body would force him to sleep.

and if he is able to stay awake would he lose that sleeping brain part function?

I guess it depends on what part of the brain does the anesthesia affect, but just in general.

I don't need a big technical explication as I wouldn't understand it :).

If a medical provider uses local anesthesia on say the nose or ears (a location near the brain), could it extend to the brain and put part of the brain to "sleep"?

Would the patient be able to stay awake or could the anesthetic render him unconscious?

If the patient is able to stay awake, would he instead lose the function of the affected region of the brain? I realize this could depend on the exact region of the brain, but just in general, is it possible?
