In an era where healthcare systems globally are working to minimize their environmental impact, one surprising focus has come to light: the operating room. Hospitals are committed to enhancing human health, but some anesthetic gases used during surgery can be a major source of greenhouse gas emissions. Inhaled agents like desflurane, sevoflurane, and nitrous oxide are commonly used in general anesthesia. Most of these gases are emitted into the atmosphere after use, where they can be strong greenhouse gases. Desflurane, especially, has a high global warming potential compared to other anesthetic agents used. To address this issue, hospitals and anesthesia departments are turning to greener practices. Numerous institutions have either phased out or stopped using high impact anesthetic gases and are opting for alternatives that have less impact on the environment. Smaller doses of anesthetic gas are also becoming more popular, as are low-flow anesthesia techniques. Technology is helping to make this transition. Today’s anesthesia machines enable more accurate gas delivery, which helps minimize waste. Scientists are also working on systems that can capture and recycle anesthetic gases before they enter the atmosphere. Importantly, environmental sustainability does not compromise patient care. Research has demonstrated that numerous green anesthesia practices can achieve the same level of safety and effectiveness without causing environmental damage. In the fight against climate change, green anesthesia proves that even minor adjustments in OR practice can have a significant impact. When hospitals are able to deliver high-quality care while also being environmentally responsible, they can contribute to the health of their patients and the health of the planet for generations to come.
