Sustainable Anesthesia: A Scoping Review of Carbon Reduction Strategies
Authors' conclusion
Our analysis shows that various strategies, including low-emission techniques, equipment reuse, waste reduction, and telemedicine, can significantly lower anesthesia-related CO2e without compromising patient safety.
Study context
