Registered outcomes8
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Cerebral blood flow | Up to 3 hours (measured on the day of surgery prior to the surgical procedure) | Blood flow measured in milliliters per minute through selected regions of the brain as determined by Positron Emission Tomography |
| Secondary | Cerebral metabolic rate of oxygen | Up to 4 hours (measured on the day of surgery prior to the surgical procedure) | Cerebral oxygen consumption in selected regions of the brain as determined by Positron Emission Tomography |
| Secondary | Blood flow through body organs in milliliters per minute as determined by Positron Emission Tomography | Up to 4 hours (measured on the day of surgery prior to the surgical procedure) | Blood flow in various body organs supplied by the systemic circulation |
| Secondary | Blood pumped out by the heart per minute (cardiac output) | Up to one day | Cardiac output as determined by Positron Emission Tomography and/or by beat-to-beat determination by analysis of the arterial blood pressure waveform |
| Secondary | Ischemic lesions | Up to 3 days | Ischemic lesions possibly associated with vasopressor use as detected on the postoperative MRI examination |
| Secondary | Cerebral tissue oxygen saturation | Up to one day | Cerebral tissue oxygen saturation as measured with near infrared spectroscopy (NIRS) |
| Secondary | Bispectral Index (BIS) | Up to one day | Depth of anesthesia as measured by BIS |
| Secondary | Organ metabolic rate of Oxygen | Up to 3 hours (measured on the day of surgery prior to the surgical procedure) | Oxygen consumption in various organs as measured by Positron Emission Tomography |
