摘要

The present invention relates to an anesthetic composition containing an anhydrous fluoroether compound and a physiologically acceptable Lewis acid inhibitor (e.g. water, butylated hydroxygene, methylparaben, propofol, thymol). This composition exhibits improved stability and does not degrade in the presence of a Lewis acid. IMAGE
