Gas tamponade for retinal surgery isn’t usually the first thing that comes to mind when we think of greenhouse gas emissions, but a new study says that maybe it should. The study assessed the carbon footprint of different gas delivery methods in several U.K. hospital centers and found that there’s significant waste associated with large gas cylinders. The gases in question are fluorinated gases commonly used in vitreoretinal surgery. They’re also among the most potent of the greenhouse gases. Fortunately, the literature suggests that reducing these emissions could result in health benefits, cost reductions in health care delivery and increased patient satisfaction. Read More
