Relative analgesia (Happy gas)
Happy gas, or nitrous oxide, is a colourless, odourless gas that can provide temporary and reversible ‘sedation’ and comfort. For patients who require more anxiety busting techniques than just a calm environment and local anaesthetic, happy gas is a safe and reliable way to overcome fear.
Nitrous oxide (N2O), more commonly referred to as happy gas, is used as a local sedation method. Nitrous oxide is effective as a sedative because it relaxes patients with the pleasurable feelings it emits. Nitrous oxide’s usefulness also stems from how quickly it works and that its effects are reversible. For those and other reasons, nitrous oxide is widely considered to be a safe sedation method.
We have Happy gas plumbed directly into each surgery, and our team is trained well as to how to use it. Normally, a mix of N2O and oxygen is given in about a one to one ratio. Some patients need more, some much less. The effects of the happy gas are ‘a feeling of calmness and happiness’ as well as a reduction in anxiety. Some funnier side effects are laughing and giggling, as well as hearing echoes of the dentists and nurses voices.
