Hallways
Along with halothane and nitrous oxide ( laughing gas , N 2 O), flurans are the most important inhalation narcotics . They are characterized by low molecular weight, high vapor pressure and low boiling point . They contain an ether bridge as a functional group and are multiply halogenated. This is why they are also called "halo ethers".
Flurans have very good hypnotic and slightly pronounced analgesic properties, as well as, to varying degrees, low muscle-relaxing properties. Mononesthesia for painful interventions is therefore not recommended for humans; the corridors are then to be combined with analgesics (balanced anesthesia). All volatile anesthetics lead, depending on the dose, to loss of consciousness, respiratory depression and decline and / or cessation (standstill of reflex activity).
Hallways are colorless and non-flammable. They are inert and relatively stable to light. They do not interact with metals or plastics, but can partially dissolve plastics or their additives. They have a pungent odor and are irritating to the upper respiratory tract . Only sevoflurane has a mild, pleasant odor and is therefore the only volatile anesthetic that is also suitable for induction of anesthesia with a mask.
The flurans include enflurane , isoflurane , sevoflurane , desflurane and methoxyflurane . They are commercially available as liquids. The largest suppliers of corridors are Abbott Laboratories and Baxter International . To enable easy identification, Flurane containers are provided with a color code : enflurane (orange), isoflurane (violet), sevoflurane (yellow) and desflurane (blue).
