Is it true that some people remain aware during surgery, despite anesthesia?

Awareness under anesthesia is a real phenomenon. It rarely occurs, but when it does occur, it gets a lot of press; so it seems to occur more than you would expect. The actual incidents, with twenty million anaesthetics accomplished in the United States is approximately one to two per thousand, which means twenty-six thousand cases of awareness under anesthesia. That being said, most cases of awareness under anesthesia do not feel pain. They hear things. They think they may have been dreaming, but they are not in pain. Some patients are, and that's been reported, as well. The most common cases of awareness under anesthesia have been with coronary artery bypass graft anesthesia, because they used a balanced technique with a lot of narcotics, and avoided some of the inhalation agents, and the cracking of the sternum, per se, has been what many people remember under anesthesia.
