Medical nitrous oxide has played an important role in anaesthesia over many years.
Medical nitrous oxide is used as an anaesthetic and analgesic agent:
It acts synergistically when combined with other inhaled or intravenous anaesthetic agents.
It has little effect on respiration and circulation during anaesthesia.
Its rapid ‘wash-in’ (uptake) and ‘wash-out’ (fast elimination) allows faster emergence when used with a modern inhaled anaesthetic than when the anaesthetic is used alone.
