There is no need for a long interval between the two, and the doctor will take the medicine according to the situation. For example, some operations only take a few hours, and some operations take more than ten or twenty hours. Other patients have surgery in the morning and then in the afternoon.

I said that general anesthesia is the safest and most reliable, which means that there is the least possibility of complications or sequelae. Simple anesthesia is impossible to wake up, and it is only a delay at most.

The situation of "deep coma and finally becoming a vegetative state" after anesthesia may be a serious accident during anesthesia and surgery, such as prolonged hypoxia, cerebrovascular accident and cardiac arrest.

Generally speaking, patients can be fully awake within 10 minutes after general anesthesia. The interval between two operations depends on the needs of the operation, and anesthesia is not the limiting factor.
