Inhaled Anesthetic 2023 Challenge
Reduce your facility inhaled anesthetic carbon emissions by 50%!
Reduce Inhaled Anesthetic Atmospheric Waste
Inhaled anesthetics are potent greenhouse gases. Waste anesthetic gases (WAGs) are routinely vented off facility rooftops, where their emissions to the outdoor environment are currently not controlled. Several simple strategies from the Anesthesiology Sustainability Checklist can reduce these emissions, and serve to protect public health, without compromising patient care:
- Utilize low fresh gas flows
- Avoid high impact inhaled anesthetics: desflurane, nitrous oxide
- Consider intravenous and regional techniques
- Decommission/avoid installing nitrous oxide centralized piping, and substitute portable tanks that remain closed between use
- Consider investing in WAG trapping (for volatiles only) or WAG destroying (all inhaled anesthetics, including nitrous oxide) technology, only after all aforementioned interventions are maximized and institution cost/benefit analyses performed
Inhaled Anesthesia Climate Initiative: Project Drawdown
Inhaled Anesthesia Climate Initiative Project Drawdown is an international campaign that aims to benchmark facility-level inhaled anesthetic carbon footprints to compare and inspire performance improvement efforts. Project Drawdown participants can anonymously pool their annual facility’s inhaled anesthetic procurement volumes, and contribute to a growing body of knowledge to help leverage carbon mitigation in the health care sector across the globe. Participants may opt to receive a report of their facility’s carbon footprint results, and can track progress over time.
How’s your facility doing?
Some institutions have made great progress in reducing their inhaled anesthetic footprint, for example, through removal of desflurane from the drug formulary or by relocating desflurane vaporizers to a locked cabinet and limiting access to special request. Other facilities are just beginning to pay attention to inhaled anesthetic pollution. It is helpful to measure the current state of emissions and track mitigation progress. By opting to participate in the Project Drawdown study, you can contribute to a growing body of knowledge to help leverage carbon reduction in the healthcare sector across the globe. Participants may opt to receive a report of their facility carbon footprint results and can track changes over time.
