Oxygen and inhaled anaesthetic agent consumption could be significantly reduced if anaesthetic procedures were audited and adapted, found a new study, published in the Journal of Small Animal Practice (JSAP). This in turn could lead to reduced greenhouse gas emissions and financial expenditure.

The study “Sustainable veterinary anaesthesia: single centre audit of oxygen and inhaled anaesthetic consumption and comparisons to a hypothetical model”, retrospectively reviewed the records of 100 consecutive anaesthetics from a typical week at the Queen Mother Hospital for Small Animals, Royal Veterinary College, UK. Cases were included if the anaesthetic had an accompanying record that contained the animals’ bodyweight and all the 5-minute recordings of fresh gas flows and vaporiser settings for the duration of the anaesthetic. The volume of oxygen and inhaled anaesthetic agent (IAA) used per 5-minute period were calculated based on the records. The carbon footprint through greenhouse gas emissions was calculated in carbon dioxide equivalents (CO2e).
