New study tests brain monitor combo to prevent anesthesia awareness in seniors

This study looks at whether adding a special brain-wave display (called density spectral array, or DSA) to the standard monitor (bispectral index, or BIS) helps doctors better detect when older adults (65+) wake up from anesthesia. The goal is to reduce the risk of being aware during surgery. The study will observe 70 patients undergoing planned procedures lasting 1-3 hours.
