The basics of balanced general anesthesia developed since 1956 and the update on existing practices of intravenous induction anesthetics and inhalational anesthetics are discussed. Some of the progressive anesthetics discussed are propofol instead of barbiturate such as thiopental or methohexital, inhalational anesthetic halothane, C[F[subscript]3]CHBrCl replaced by four polyhalogenated ethers and nitrous oxide and sevoflurane replaced with 100% dioxygen to flush out residual anesthetic in preparation for emergency.
