Abstract:
Objective To compare cerebral oximetry(rSO 2 %)and somatosensory evoked potential (N 35 ) in their accuracy in monitoring cerebral perfusion during carotid endarterectomy procedure under general anesthesia. Methods Ten patients (6 males, 4 females), scheduled for selective carotid endarterectomy, were enrolled in the study. Their rSO 2 %and N 35 were also continuously monitored and recorded during perioperative periods. The patients' cognitive function was evaluated at the same time. The MAP, HR, SpO 2 were continuously monitored during operation. Results There was a significant difference in rSO 2 % between that at the period of elamping and that at the period of declamping of the carotid artery. No patients suffered from cognition dysfunction during perioperative period. Conclusion With comparison to the amplitude of N 35 it was rSO 2 % which was earlier to show alteration in cerebral perfusion in case of cerebral oxygen deficit. In monitoring cerebral perfusion, rSO 2 % was better than N 35
