Anesthesia Gases are Warming the Planet

April 7, 2015 | Science Magazine

A new study revealed that commonly used ether anesthetics are contributing to climate change. Scientists argue that the elimination of desflurane, the most potent contributor (1 kilogram of desflurane equates to 2500 kilograms of CO2), would help.

Penn Researchers Looking for a Knockout Anesthesia

March 3, 2015 |

A leading anesthesia lab at the University of Pennsylvania has developed a high-throughput screening technique to identify new and novel compounds that may be general anesthetics, and has identified two for further study. The drug industry has not developed any truly novel general anesthetics since the 1970s, despite the myriad side effects associated with them. Dr. Rod Eckenhoff is particularly interested in addressing the cognitive issues associated with anesthesia in the elderly and very young.

Researchers Warn on Anesthesia, Unsure of Risk to Children

February 25, 2015 | The New York Times

A combination of experiments completed with monkeys and with children have suggested that multiple, long doses of anesthesia before the age of three are directly linked to higher incidences of learning disabilities. Experts are demanding studies regarding whether or not single doses have a similar effect, and are clamoring for a new anesthetic that is safe for pediatric use.

New Strategies for Anesthesia

February 23, 2015 | MIT News

Dr. Emery Brown, Professor of Medical Engineering and Computational Neuroscience at MIT and anesthesiologist at Mass General, acknowledges that although anesthesia has been used in the US for more than 160 years, it remains largely misunderstood. Dr. Brown's research focuses on the neuroscience underlying anesthesia, and his recent studies suggest that brain imaging during anesthesia may in fact allow for more precise monitoring of anesthetic depth.

Deep Sedation for Colonoscopy Might Not Be Safe

November 19, 2014 | Consumer Reports

A recent study has demonstrated that use of anesthetics, typically propofol, in colonoscopy patients leads to a 50 percent increase in risk of aspiration pneumonia. It has aso been shown to carry other detrimental side effects such as confusion, irregular heartbeat, and seizures.
