Anesthesia Awareness

Awareness is extremely rare and occurs when a patient becomes conscious during a surgical procedure under general anesthesia and has recall of events. These cases rarely occur during high-risk surgery where the patient’s condition does not allow for the usual dosages of medications and gases to be given.

Nil per os, Latin for “nothing by mouth”
