We describe an easy protocol specifically designed to reach precise and controlled concentrations of sevoflurane or isoflurane in vitro in order to improve our understanding of mechanisms involved in the epithelial lung injury and to test novel therapies for acute respiratory distress syndrome.

We describe a model of hydrochloric acid-induced acute respiratory distress syndrome (ARDS) in piglets receiving sedation with halogenated agents, isoflurane and sevoflurane, through a device used for inhaled intensive care sedation. This model can be used to investigate the biological mechanisms of halogenated agents on lung injury and repair.
