Dreaming and electroencephalographic changes during anesthesia maintained with propofol or desflurane.

Dream recall after anesthesia is similar for propofol (27%) and desflurane (28%), contrary to earlier reports that propofol produces more dreaming. Times to interview were similar between groups, but propofol patients had lower bispectral index values at interview. During surgery, propofol patients showed more and faster spindle activity than desflurane patients. In the 5 minutes before interview, dreamers had fewer spindles and more high-frequency power than nondreamers. Anesthetic-related dreaming appears to occur just before awakening and is associated with a rapid eye movement-like electroencephalographic pattern.
