Continuous recording of global cerebral electrical activity using the cerebral function monitor is helpful to delineate the safety of induced hypotensive anesthesia in elderly patients during total hip replacement (THR). Severe hypotension and cardiac arrest following the use of polymethyl methacrylate bone cement has been well documented. This adverse cardiovascular response may be attenuated by a deliberate hypotensive anesthetic technique. In this preliminary study, 30 patients undergoing THR were monitored with the cerebral function monitor during moderate hypotensive anesthesia. Minimal transient changes in global cerebral electrical activity were seen in patients with metastatic disease of the hip complicated by pathologic fractures. No changes were seen in patients with rheumatoid arthritis or osteoarthritis.
