Temperature Dependence of the Potency of Volatile General Anesthetics

Abstract

When performing room-temperature in vitro experiments on simple mammalian preparations with a volatile anesthetic, the aqueous-phase (but not the gas- phase) minimum alveolar concentration calculated at normal body temperature is, to a first approximation, the appropriate choice for a clinically relevant anesthetic concentration. Recommended aqueous-phase minimum alveolar concentration values (in MM) for desflurane, enflurane, halothane, isoflurane, and sevoflurane have have been calculated.
