In this episode of The Evidence, Claudia Hammond is joined by a panel of experts to discuss the science of anaesthesia. It’s estimated that around the world, more than 250 million people receive surgery requiring anaesthesia each year. But there are still plenty of unknowns. What happens to our brains and our consciousness when we’re put to sleep? Why do so many people around the world still not have access to safe anaesthesia? And could the colour of your hair affect how much anaesthesia you need? In front of a live audience at Wellcome Collection in London, Claudia is joined on stage by Dr Kevin Fong, a consultant anaesthetist at University College London Hospitals and professor of public engagement and innovation at University College London; Jennifer Hunter, emeritus professor of anaesthesia and senior research fellow at the University of Liverpool; Emmanuel Stamatakis, professor of neuroscience at the University of Cambridge studying the science of consciousness; and Bruce Biccard, professor of anaesthetic science at the University of Oxford and author of the book Safer Surgery for Africa: Challenges and Solutions. Producer: Dan Welsh Editor: Martin Smith Production coordinator: Stuart Laws Sound engineers: Emma Harth and Steve Greenwood
