Anesthetic gases (nitrous oxide, halothane, isoflurane, desflurane, sevoflurane), also known as inhaled anesthetics, are administered as primary therapy for preoperative sedation and adjunctive anesthesia maintenance to intravenous (IV) anesthetic agents (i.e., midazolam, propofol) in the perioperative setting.[1] Inhaled anesthetics enjoy regular use in the clinical setting due to chemical properties that allow rapid introduction of an agent into arterial blood via the pulmonary circulation as compared to the more circuitous route of venous circulation.[2] The significance of rapid therapeutic effects allows for efficient induction and discontinuation of sedation induced by these agents; providing proper amnesia, anesthesia, and a faster recovery period in postoperative care as compared to IV agents.[3]
