In this case report, we describe a nonagenarian patient who could respond completely to verbal commands at a Bispectral Index (BIS) value of 52 after epidural lidocaine and IV propofol anesthesia. Measured blood lidocaine and propofol concentrations were 0.69 µg/mL and 0.74 µg/mL, respectively. Intraoperative awareness even in the recommended BIS range of 4060 remains possible.
