When it comes to anesthetic gases, one of them is not like the others. Desflurane, one of three general anesthetics used in surgery to safely put patients to sleep, has a global warming potential 2500x greater than carbon dioxide. Due to its devastating impact on the atmosphere, there is a global initiative to ban desflurane with Scotland leading the charge. In Canada, anesthesiologists like Dr. Anita Rao are bringing climate action to work with sights set on a complete ban, one hospital at a time.
