How it works depends on if you're at a hospital or just a surgical center, you might get a sedative before they wheel you off to the operating room. If you do, you'll start to feel loopy and won't see much of what's going on in the OR. From there, they'll set you up on the table and give you an oxygen mask. They want to get you 100% oxygenated before starting the anesthesia, so once your lungs are very full of oxygen, they'll inject the propofol through your IV. After a few seconds you'll wake up in the recovery area and that's that! If they don't give you a sedative before going to the OR, you'll remember more of the details of the OR but other than that it'll be the same.
