AnaesthesiaXenon has been used as the general anaesthetic, but xenon is much more expensive compared to conventional anaesthetics.Xenon interacts with several different ion channels and receptors, and as several theoretically multi-modal inhalation anaesthetics, these interactions are likely complementary. Xenon is also a high-affinity glycine-site NMDA receptor antagonist. However, it varies in particular from other NMDA receptor antagonists in that it is not neurotoxic and inhibits the nitrous oxide and ketamine neurotoxicity, while actually forming neuroprotective effects. Unlike nitrous oxide and ketamine, xenon does not stimulate dopamine efflux in the accumbens of the nucleus.
