Cerebral oximetry to reduce perioperative morbidity

Abstract

The use of cerebral oximetry to guide intraoperative management has been shown to improve patient outcomes in cardiac surgery. This pilot trial assessed the feasibility of performing a similar study of outcome in patients over the age of 70 years undergoing non-cardiac surgery. Patients over the age of 70 years undergoing total knee or hip arthroplasty or bowel resection surgery were randomly assigned to have cerebral oximetry values monitored (intervention group) or not monitored (control) while under general anaesthesia. Indicators of proof of concept were: rate of complications, rate of cerebral desaturation, relationship between cerebral desaturation and complications, and anaesthetist r..
