1) Doc presents new study suggesting ‘lowering the flow of anesthetic gas’ in patients to save the planet – 1 hour of surgical anesthesia equivalent to driving as many as 470 miles – Anesthesia the next target in climate battle: Docs suggest reducing anesthesia: Would you suffer to combat climate change?

NY PostDr. Mohamed Fayed, a senior anesthetist at Detroit’s Henry Ford Health, made the suggestion during the American Society of Anesthesiologists’ annual conference last Friday in Orlando, Florida. “Global warming is affecting our daily life more and more, and the reduction of greenhouse gas emissions has become crucial,” he said. Dr. Fayed added, “No matter how small each effect is, it will add up. As anesthesiologists, we can contribute significantly to this cause by making little changes in our daily practice — such as lowering the flow of anesthetic gas — without affecting patient care.”

Study press release: “Anesthesiologists can play a role in reducing the greenhouse gas emissions that contribute to global warming by decreasing the amount of anesthetic gas provided during procedures without compromising patient care, suggests new research being presented at the American Society of Anesthesiologists’ ADVANCE 2023, the Anesthesiology Business Event.” [Climate Depot Note: The American Society of Anesthesiologists’ website appears to have pulled the article. But it is available here. & here

Research notes that inhaled anesthesia accounts for up to 0.1% of the world’s carbon emissions, which are regarded as the primary driver of global climate change. An hour of surgery using an inhaled anesthetic is equivalent to driving as many as 470 miles, according to a 2010 study.

Reuters: Cannabis users may need ‘more than TWICE usual dose’ of anesthesia for surgery – “People who regularly use cannabis may need more than twice the usual dose of anesthesia for surgery, a U.S. study suggests.”

2) Harvard Medical School Will ‘Integrate Climate Change’ Into M.D. Curriculum

The Harvard Crimson: A Harvard Medical School committee voted last month to embed climate change into the school’s curriculum. … The new climate change curriculum will examine the impact of climate change on health and health inequality, applications of these impacts to clinical care, and the role of physicians and health institutions in arriving at climate solutions. … HMS student Madeleine C. Kline said: “Every student who comes through the Medical School will leave with an understanding of what climate change is and what it means for their patients,” she said. “I think it is going to mean a lot for their patients.”
