In this second of our Anaesthesia 2024 conference podcasts, recorded in Glasgow in May 2024, Drs Helgi Johannsson, Lucy Brooks, and Paul Southall discuss the latest developments in sustainable anaesthesia.  They look at the NHS's decomissioning of desflurane, use of nitrous oxide, masks and gowns, and the importance of local leadership and advocacy in making positive, sustainable change.
