Which one of the following is the fastest acting inhalational agent?
a. Blood gas coefficient is the indicator of induction and recovery time. Agents with low blood gas coefficient have fast induction and recovery.
b. So fastest acting inhalational agent is desflurane (B/G coefficient of 0.42) followed by cyclopropane (0.44), nitrous oxide (0.47), sevoflurane (0.69), isoflurane (1.38), enflurane (1.8), halothane (2.4), ether (12) and methoxyflurane (15).
