Xenon is the only inert gas that possesses anaesthetic properties under normobaric conditions(Krypton and Argon show anaesthetic properties only in hyperbaric conditions). Xenon was identified as an anaesthetic gas in 1951 but was largely forgotten, and then was rediscovered in 1990. The gas cannot be manufactured but is recovered from the air by the process of fractional distillation. Its cost of production is 100 times that of Nitrous oxide, which makes xenon a costly affair. Physical Properties: Inert gas with high density ( heavier than air ) and high viscosity which increases the work of breathing.
? Noninflammable and non-explosive. Anaesthetics properties: Possesses analgesic effects, MAC 70. Blood gas coefficient is lowest (0.14), therefore induction and recovery are rapid ( three times faster than desflurane). Metabolism: NOT METABOLISED BY HUMAN TISSUE AND IS EXCRETED AS SUCH…
