The blood/gas partition coefficients for the new volatile anesthetic agent desflurane (I-653), sevoflurane, isoflurane, and halothane were determined, simultaneously, in 8 human volunteers to compare the solubilities of these agents in blood. The blood/gas partition coefficient for desflurane [0.49 +/- 0.03 (mean +/- SD)] was smallest, followed by sevoflurane (0.62 +/- 0.04), isoflurane (1.27 +/- 0.06), and halothane (2.46 +/- 0.09). Differences among the anesthetic agents were significant (P less than 0.001). The results of this study confirm that among these agents the solubility of desflurane in human blood is the smallest. The results suggest that the washin and washout of desflurane will be more rapid than that of sevoflurane, isoflurane, and halothane, and the washin and washout of sevoflurane will be more rapid than that of isoflurane and halothane.

UI MeSH Term Description Entries
D007530 Isoflurane A stable, non-explosive inhalation anesthetic, relatively free from significant side effects.
D008297 Male Males
D008738 Methyl Ethers A group of compounds that contain the general formula R-OCH3. Ethers, Methyl
D004987 Ethers Organic compounds having two alkyl or aryl groups bonded to an oxygen atom, as in the formula R1–O–R2.
D006221 Halothane A nonflammable, halogenated, hydrocarbon anesthetic that provides relatively rapid induction with little or no excitement. Analgesia may not be adequate. NITROUS OXIDE is often given concomitantly. Because halothane may not produce sufficient muscle relaxation, supplemental neuromuscular blocking agents may be required.

D000077149 Sevoflurane A non-explosive inhalation anesthetic used in the induction and maintenance of general anesthesia. It does not cause respiratory irritation and may also prevent PLATELET AGGREGATION.
