How does anesthesia make you fall asleep?


Rate This Answer

"Anesthesia" is not a drug, but a combination of drugs to render people unconscious and pain-free during surgery. Anesthesia is NOT sleep. It is drug-induced unconsciousness. We call it sleep, because that's what it looks and feels like, but it's much different. It's rare for us to use gases to put people to sleep (except little kids). If you have had anesthesia and were breathing something, it was oxygen, and you got drugs through your IV. That works much more quickly than breathing gases in. We turn the gases on after you are asleep to keep you under.
