2009 -- For years, it has been widely assumed that older adults may experience memory loss and other cognitive problems following surgery. But a new study by School of Medicine researchers questions that assumption. In the 575 patients they studied, the investigators did not detect any long-term cognitive declines attributable to surgery.

Scientists Identify 'Itchy' Neurons In Mice
NPR.org
Aug. 7,
2009 -- Scientists know surprisingly little about the common sensation of itching. But in a recent study of mice, researchers identified specific nerve cells that pass along an itch signal to the brain. And these cells appear to be independent of the pathway for pain. WUSTL anesthesiology professor and co-author Zhou-Feng Chen comments on the study that was published in Science Express.

New Study Raises Questions on Anesthesia Monitoring System
The Washington Post
and 1 others
March 14,
2008 -- The horrifying experience of anesthesia awareness happens to between 20,000 and 40,000 Americans every year. A WUSTL study in the New England Journal of Medicine led by WUSTL anesthesiology professor Michael Avidan is raising questions about a monitor used by about 60 percent of U.S. operating rooms in an effort to prevent these frightening cases.

March 13,
2008 -- Article on anesthesia awareness.
Patients say they wake up during surgery, unable to move or scream.
Some experts have said special brain-wave monitors were the best way to prevent anesthesia awareness. Now, in a big setback for efforts to prevent it, the first large, independent test of the monitors shows they are no better than older technology.
WUSTL medical school researchers led by anesthesiology professor Michael Avidan comments.
The study was published in Thursday's issue of the New England Journal of Medicine.
