The effects of volatile anesthetic agents on pulmonary surfactant function.
The purpose of this article is to review the findings from research directed at understanding the effects of volatile anesthetics on the respiratory surface known as pulmonary surfactant. Anesthetics have long been known to have a disruptive effect on biological membranes. This review will highlight the interactions of volatile anesthetics with pulmonary surfactant. This paper has emphasized the interaction of volatile anesthetics with the pulmonary surfactant monolayer versus the lipid bilayer. The goal of this review is to uncover to what extent this understanding has progressed in forty years. Although the goal is quite broad, the information gathered and the advice given is specific. Theories of anesthesia and surfactant structure and function are summarized and discussed in light of early physico-chemical approaches and extend to an era where powerful new three-dimensional structural techniques can be used to answer this question.
