Sevoflurane

Sevoflurane is a drug used as an anesthetic. It was discovered twice by Ross Terrell and Bernard M. Regan.

History
Sevoflurane is commonly used for outpatient anesthesia, including induction in children and infants. It is also used in veterinary medicine, boasting a rapid induction and recovery rate "due to a relatively low blood/gas solubility coefficient". Dentists and surgeons tend to use it for operations on minors. It is preferred for mask induction as mucous membranes are less irritated by it during administration.

Though having high ratings for safety, sevoflurane recently went under review for potential neurotoxicity, with a few reports noting similar characteristics to halothane hepatotoxicity.

Criminal Minds
In Mr. Scratch, serial killer by proxy Peter Lewis used sevoflurane as an ingredient for an extremely powerful dissociative agent, which would induce psychotic breaks in potential victims. Reid states that the drug puts people into a waking dream. However, the episode depicts sevoflurane being administered in an aerosolized form, which is impossible, as the drug has to be inhaled directly via breathing apparatus, such as a mask or a nose tube, for it to achieve a noticeable effect.
