How patient positioning affects brain monitoring during anesthesia

This trial tests whether adding an extra visual display (density spectral array) to the standard brain monitor helps doctors better track anesthesia depth in older adults. It's designed for people 65+ having short surgeries with propofol and no muscle relaxants.

This study tests whether training anesthesia providers to use EEG (brain-wave monitoring) helps them give better anesthesia. Part A trains doctors and nurse anesthetists; Part B watches how this training affects patient outcomes during surgery.

This study checks if a head-down position (called Trendelenburg) during laparoscopic hysterectomy affects a brain wave monitor (Patient State Index) that measures how deep your anesthesia is.

This study examines how well a brain-monitoring device (called a bispectral index monitor) tracks your level of consciousness during surgery when you receive anesthesia through an IV. The findings may help doctors better manage anesthesia and keep you safer during procedures.

This study tests whether using special brain monitors during and after surgery can help older adults recover better after major abdominal surgery. It looks at how these monitors might reduce confusion or other problems after an operation.

This study looks at how anesthesia changes brain activity using EEG (a non-invasive brain wave recording). Researchers want to see if these changes relate to how conscious you are during surgery. This could help doctors provide safer anesthesia care.
