I can't. Accept any anesthesia that will make you unconscious at a slight depth, even if it is not general anesthesia. Don't eat for at least eight hours before anesthesia and keep an empty stomach. This reason is to avoid the possibility of nausea and reflux when anesthesia is unconscious, and tracheal blockage and infection will be more serious. Some people think it's no big deal to steal something, and then cheat the doctor not to eat it. But if the real food returns to the lungs, it's your own fault!
