A systematic review of clinical trials confirms that including nitrous oxide in the gas mixture for general anaesthesia has minor short-term benefits and does not impact most patient safety outcomes. However, no risk-benefit analysis of nitrous oxide should ignore its known environmental effects. If continued nitrous oxide use is supported, strategies to minimise and monitor the contribution of medical nitrous oxide to global warming are vital.

A recent human epidemiological study in this issue of British Journal of Anaesthesia examined the association between anaesthesia exposure in pregnant women undergoing appendicectomy or cholecystectomy and the subsequent diagnosis of behavioural disorders in their offspring. When compared with unexposed children, prenatally exposed children had ∼30% greater likelihood of a diagnosis of disruptive or internalising behavioural disorders. ⋯ It is, therefore, possible that the findings are related to maternal and fetal inflammation than to anaesthesia exposure. As there is no causal evidence for the implication that anaesthesia and surgery induce such pathologies, it is unwise to consider alternative treatments when surgery is indicated in pregnant patients.
