An operation at King George Medical Hospital, 1915
Dentists and physicians would possibly favor sevoflurane over isoflurane, as sevoflurane is the least environmentally dangerous ether
Not all greenhouse gases are created equally. Some, like carbon dioxide, linger within the environment for hundreds of years, whereas others, comparable to methane and nitrous oxide, are considerably stronger of their warming results. Inhaled anesthetic gases, although a small share of whole emissions, have an outsized influence attributable to their excessive international warming potential and direct launch into the environment.
Anesthesia gases contribute to greenhouse gasoline emissions, however options are rising to mitigate their influence. Emissions in healthcare come from varied sources, together with waste administration, single-use plastics, transportation, and meals providers. In addition, 3% of healthcare’s emissions stem from inhaled brokers used throughout anesthesia.
A examine carried out at Michigan Medicine reveals that the usage of much less polluting inhaled anesthetic brokers decreased dangerous emissions by 50% in a single 12 months with out impacting affected person security or outcomes.

“Tens of hundreds of individuals bear basic anesthesia at Michigan Medicine yearly. Inhaled anesthetics are a pure space to pursue reductions in emissions as a result of, as greenhouse gases, they’re so disproportionately dangerous for the setting,” mentioned Douglas Colquhoun, M.B.Ch.B., assistant professor of anesthesiology at U-M Medical School.
“We’ve proven that small adjustments in our follow result in huge adjustments for the setting and, importantly, no adjustments for the sufferers.”
The findings culminate from The Green Anesthesia Initiative, launched at Michigan Medicine in March 2022, aimed to cut back the usage of nitrous oxide, make the most of much less environmentally dangerous inhaled fluorinated ethers, and enhance the usage of intravenous anesthetics.
Hospitals and medical professionals comparable to dentists are taking steps to decrease the environmental footprint of anesthesia by means of:
- Lower-GWP anesthetics: The initiative inspired suppliers to cut back nitrous oxide (which is 270 instances stronger than carbon dioxide at warming the setting) and favor sevoflurane over isoflurane, as sevoflurane is the least environmentally dangerous ether. These adjustments resulted in a mean lower of greater than 14 kg per case in CO2 equivalents.
- Total Intravenous Anesthesia (TIVA): Using IV-based anesthesia, comparable to propofol, eliminates the necessity for inhaled gases and reduces greenhouse gasoline emissions.
- Gas Capture Technologies: Some hospitals are adopting techniques to seize and safely eliminate anesthetic gases slightly than venting them instantly into the environment.
The crew in contrast the output of CO2 equivalents historically used to measure the impact of greenhouse gases on the setting, in addition to the quantity of anesthetic used and affected person outcomes comparable to post-surgery nausea and vomiting, ache scores, and unintended consciousness and recall of the surgical procedure. There have been no adjustments in measured depth of anesthesia, ache scores, or postoperative nausea and vomiting.

“I feel the essential factor that we confirmed was that it’s attainable to considerably cut back the environmental influence of anesthesia. Even past the examine interval, we decreased our emissions by an enormous quantity in underneath three years.
“We did this whereas modernizing our care and bettering security for sufferers. This is a good instance of the place aware decisions, know-how, and schooling all come collectively to make care higher for our sufferers – each instantly within the OR and within the setting during which all of us stay,” mentioned David Hovord, M.B. B.Chir, scientific assistant professor of anesthesiology.
“Our particular person and crew efforts to save lots of the planet are important. The carbon emissions discount accomplishments of anesthesiology and help groups are a degree of delight at Michigan Medicine, as they’re an illustration of creativity, persistence, and teamwork,” mentioned Tony Denton, Michigan Medicine’s senior vp and chief environmental, social, and governance officer.
“These spectacular outcomes present that we will redesign our long-standing approaches to care with out compromising affected person security, high quality, and outcomes. This is a good instance of what we will do to cut back environmental hurt and enhance public well being throughout the communities and society we serve,” he mentioned.
“We ought to all be proud and grateful for this essential collaboration which emphasizes Michigan Medicine’s day by day dedication to steady enchancment whereas discovering new options that may save our planet and lives, concurrently.”
