It works so quickly because we give you a large dose to induce general anesthesia quickly. Propofol can be given in smaller doses for sedation, but for general anesthesia we want you to go to sleep quickly in order to avoid stage 2 which is the intermediate plane of consciousness. That’s when patients are hyper-excitable and disinhibited. Kind of like an angry drunk who wants to fight with everyone. Beyond just being annoying, patients can do things like go into laryngospasm, vomit, aspirate, or pull out IV lines. So that’s why we make you go to sleep so quickly.
