Abstract：Objective To observe the effects of temporary carotid artery occlusion on regional cerebral oxygen saturation (rScO2) during carotid endarterectomy (CEA). Methods American Society of Anesthesiologists grades Ⅱ~Ⅲ 52 patients with carotid arteriostenoses due to atherosclerosis underwent CEA from February, 2014 to February, 2015. EEG, pulse oxygen saturation, (radial artery) blood pressure, bispectal index (BIS) and rScO2 were monitored before anesthesia induction with sufentanil, propofol and rocuronium. After trachea cannula, the total intravenous anesthesia (TIVA) was maintained with propofol and remifentanil. Heart rate (HR), mean arterial pressure (MAP), BIS and rScO2 were recorded continuously till the end of the operation. Results The insignificant changes in the rScO2 were observed 5, 10, 15 and 30 minutes after the carotid artery occlusion compared to that before the occlusion (P>0.05), but rScO2 was significantly higher 5, 10, 15 and 30 minutes after open of occluded carotid artery than those before the carotid artery occlusion and 5, 10, 15 and 30 minutes after the carotid artery occlusion (P<0.01). Conclusions The rScO2 is insignificantly influenced by the temporary carotid artery occlusion during CEA under TIVA. The rScO2 in the cerebral area ipsilateral to the carotid stenosis can be improved by CEA.
