What are anaesthetic agents?
The agents in widespread current use are isoflurane, desflurane, sevoflurane, and nitrous oxide. Nitrous oxide is a common adjuvant gas, making it one of the most long-lived drugs still in current use. Because of its low potency, it cannot produce anesthesia on its own but is frequently combined with other agents.
What are the four anesthetic agents?
Propofol, etomidate, and ketamine are the intravenous (IV) sedative-hypnotic agents commonly used to induce general anesthesia (table 1), while adjuvant agents (eg, opioids, lidocaine, midazolam) are often used to supplement the effects of the primary sedative-hypnotic induction agent (table 2).

What are anaesthetics used for?
