| '''Enflurane''' (2-chloro-1,1,2,-trifluoroethyl-difluoromethyl ether) is a [[halogenated ether]] that was commonly used for inhalational [[anesthesia]] during the 1970s and 1980s. Developed by [[Ross Terrell]] in 1963, it was first used clinically in 1966.
| |
|
| |
|
| Enflurane is a structural [[isomer]] of [[isoflurane]]. It vaporizes readily, but is a liquid at room temperature.

| ==Side Effects==
| |
| Clinically, enflurane produces a dose-related depression of [[myocardial]] [[contractility]] with an associated decrease in myocardial oxygen consumption. Between 2% and 5% of the inhaled dose is oxidised in the liver, producing [[fluoride]] ions and difluoromethoxy-difluoroacetic acid. This is significantly higher than the metabolism of its structural isomer [[isoflurane]].
| |
|
| |
| Enflurane also lowers the threshold for [[seizures]] and should especially not be used on people with [[epilepsy]]. It is also known to cause [[malignant hyperthermia]].
