Clinical Trial Summary

This study uses a CPOM Optical neuromonitor to assess the relationship between brain cytochrome C oxidase, cerebral oxygen saturation and blood pressure during surgery performed under general anesthesia.


Clinical Trial Description

During various surgical procedures, blood supply to the brain can be jeopardized either due to interruption of flow as occurs during carotid surgery, or due to inadequate arterial pressure which can occur in settings as diverse as heart surgery or shoulder surgery. This is a prospective observational study of brain oxygen levels, brain metabolism and blood pressure in 40 adult surgical patients under general anesthesia using a CPOM Optical neuromonitor. This is an observational study. The primary objective of this study is to describe the changes in redox state of brain CCO (reflecting oxidative metabolism), CBFi, and brain tissue oxygen saturation in relation to systemic blood pressure in patients during the transition from the awake state to general anesthesia. This study represents the first opportunity to assess this combined technology in adult patients and will provide important pilot data to support further investigations in brain-at-risk patients. These 40 patients will be used to help the investigators to obtain pilot data about the relationship between brain cytochrome C oxidase (bCCO), cerebral oxygen saturation (ScO2), and blood pressure using a CPOM device. No intervention will be applied. ;
