Intraoperative Awareness (AUDIO) Washington University School of Medicine Your browser does not support the audio element. Caption Sometimes a surgical patient will become aware of some of what’s happening during an operation, and in a some cases, that patient will even remember the experience later on. Anesthesiologists work to prevent that so-called intraoperative awareness, and for the last several years, many have been using an FDA-approved device designed to help prevent awarness. But a team, led by investigators at Washington University School of Medicine in St. Louis, has found that the device is no better than a less-expensive method at preventing awareness.
