Processed Electroencephalogram Monitoring and Postoperative Delirium A Systematic Review and Meta-analysis

摘要

Background: Postoperative delirium complicates approximately 15 to 20% of major operations in patients at least 65 yr old and is associated with adverse outcomes and increased resource utilization. Furthermore, patients with postoperative delirium might also be at risk of developing long-term postoperative cognitive dysfunction. One potentially modifiable variable is use of intraoperative processed electroencephalogram to guide anesthesia. This systematic review and metaanalysis examines the relationship between processed electroencephalogram monitoring and postoperative delirium and cognitive dysfunction.
