  1. The results demonstrated that there were significant differences between the two groups in terms of the duration of CPB and MHCA+SCP. The monitoring of rcSO2 indicated that there were no significant differences between the two groups in terms of intraoperative rcSO2 except for the average value of bilateral rcSO2 at baseline
