Hyperbaric oxygen (HBO₂) therapy has been approved by the FDA for a limited set of clinical indications, although there are clinical reports that HBO₂ therapy appears to be effective in a broader range of conditions, including several examples of chronic pain. We have demonstrated that HBO2 therapy causes relief of acute pain and gathered convincing evidence that HBO2 therapy activates central pathways that can produce long-lasting relief of neuropathic pain Nitrous oxide (N₂O, laughing gas) is a gas that is notable for its anesthetic, analgesic, anxiolytic and euphoric properties. We identified and localized in the rat brain the opioid receptor subtypes that mediate nitrous oxide analgesia, provided the first chemical evidence for N₂O-induced neuronal release of endogenous opioid peptides in rats and have implicated a regulatory role for NO in the neuronal release of endogenous opioid peptides. We have also reported that N₂O produces significant relief of anxiety in different animal models of experimental anxiety. This anxiolytic effect is independent of the analgesic effect of N₂O and appears to be mediated by benzodiazepine sites on the GABA receptor and also involve NO.
