Postoperative Cognitive Dysfunction Clinical Trial
Official title:
The Influence of Postoperative Cognitive Function in Patients With Sevoflurane Postconditioning on Carotid Intima Stripped
Brief summary: In order to get a better clinical plan for brain protection during perioperative anesthesia for high-risk patients - carotid intima stripped. We observing the hemodynamic changes of sevoflurane post-treatment in carotid intima stripped, the comparison of postoperative cognitive function and postoperative radiographic changes.

Primary | Change from the 1 day preoperative to the 1 day postoperative MMSE(Mini-mental State Examination) | Screening scale of cognitive function?The highest score is 30 points, 27 to 30 were divided into normal, less than 27 divided into cognitive dysfunction?But is not sensitive in the early identification of dementia, especially in mild cognitive impairment is poorer. | the 1st day before the surgery;the 1st day after the surgery | |
Primary | Change from the 1 day preoperative to the 1 day postoperative MoCA(Montreal Cognitive Assessment) | Screening scale of cognitive function?The highest score is 30 points,Add 1 score, education the following subjects in less than 12 years?Total score less than 26 divided into cognitive dysfunction?Compared with MMSE, more sensitive to mild dementia? | Time Frame: the 1st day before the surgery;the 1st day after the surgery | |
