Anesthesia and Greenhouse Gases Emissions

Abstract

Global warming is one of the biggest threats of our time, and it is primarily caused by human activities. While anesthesia is an essential component of modern medicine and is used to provide patients with pain relief and sedation during surgery and other medical procedures; the use of anesthetic agents has been linked to the production of greenhouse gases, which contribute to global warming and climate change. This has led to increased interest in understanding the environmental impact of anesthesia and identifying ways to reduce its carbon footprint. The primary greenhouse gases associated with anesthesia include nitrous oxide and desflurane, both of which are potent contributors to climate change. Nitrous oxide is particularly concerning as it has a long atmospheric lifetime and is nearly 300 times more potent than carbon dioxide in terms of its global warming potential. Desflurane, while less potent than nitrous oxide, has a very high carbon footprint due to its production process and high rate of release into the atmosphere during use. There are a number of strategies that can be employed to reduce the environmental impact of anesthesia. These include using more efficient anesthetic delivery systems, switching to less environmentally harmful agents, and minimizing waste and leaks. Additionally, efforts can be made to raise awareness among healthcare providers and patients about the importance of reducing greenhouse gas emissions from anesthesia.
