Can people normally wake up violently after from coming under anesthesia?

Sometimes: If patients are in a lot of pain and confused on emergence from anesthesia, this may manifest as a "violent" wake-up. This is more common in younger, athletic males.

Delirium: Emergence delirium is a common occurrence. It manifests as fighting; crying; abnormal behavior. Low oxygen ; pain; patient's nature are possible etiologies.

Yes: Emergence delirium is a condition, mostly seen in children, that causes people to wake up very violently. This violence may go on for about an hour and the patient is oblivious to it - sort of "the lights are on, but nobody's home." It has very typical behavior associated with it. Other people just are very confused and may be violent for that reason - this wears off much faster, though.

Emergence delirium: also called agitated emergence. It is post-anesthetic excitement, is a condition caused by anesthesia in some patients. The good news is that emergence delirium is a temporary condition.

Depends on situation: Patients with PTSD, such as war veterans, are known to be at risk for waking up with aggressive behavior after anesthesia, due to their past experiences. Otherwise, this is unusual. The anesthesiologist usually is able to control the wakeup so that it is more gradual and pleasant. Agitation on waking up may be more likely after emergency surgery or if the patient was upset when going to sleep.
