Anaethetists warn against nitrous oxide during labour
The inhaled drug has no real clinical benefit, but has a sizeable environmental impact, says updated ANZCA guidance

Anaesthetists say women should be discouraged from using nitrous oxide during labour as it has little clinical benefit, but a huge carbon footprint.
Writing in updated Australian guidance, the specialists argue inhalational anaesthetic seems effective because it provides a distraction from labour pain that forces women to focus on their breathing in-between contractions.
