- Gender: ALL
- Minimum Age: 40 Years
- Maximum Age: 80 Years
- Healthy Volunteers: f

Study Arms:
- INVOS (Type: ACTIVE_COMPARATOR): INVOS : Cerebral oxygenation (rSO2) monitoring with INVOS. If rSO2 decreased for more than 20% from patient's baseline value, simple interventions were performed to prevent brain injury. These interventions included: repositioning of head or perfusion cannulae, increasing arterial carbon dioxide tension, increasing oxygen inspiration concentration, increasing arterial blood pressure, adjusting pump flow rate, temperature decreasing, increasing of anesthetic depth and blood transfusion.
- CONTROL (Type: NO_INTERVENTION): The CONTROL arm did not have INVOS or any other cerebral oxygenation monitoring, so interventions to control cerebral oxygenation were not performed.

Based on this trial design, predict the completion outcome and termination type (if applicable).
