General Anesthetics · Pharmacology

Which of the following inhaled anesthetics has the lowest Blood:Gas partition coefficient, leading to the fastest induction and recovery?

  1. Halothane
  2. Isoflurane
  3. Desflurane
  4. Nitrous Oxide
Show answer and explanation

Correct answer: Desflurane

Desflurane has a Blood:Gas partition coefficient of approximately 0.42. Because it is relatively insoluble in blood, the partial pressure in the alveoli rises rapidly, leading to very quick equilibration with the brain and rapid emergence from anesthesia.
