According to the American Society of Anesthesiologists, anesthesia and sedation are the stages of a drug-controlled change in the patient's conditions.
The last step in this chain of state transition is anesthesia, and the chain is the following:
minimal sedation - the introduction of sedatives in a small amount, combined with local anesthesia;
superficial sedation (treatment the bright-eyed patient);
over-sedation or deep sedation (partial consciousness or treatment while asleep);
general anesthesia.
