研究疾病:

围术期神经认知障碍(perioperative neurocognitive disorders,PND)是指患者在围术期出现定向、思维、记忆、注意力、自知力等认知能力的改变。按照发病时间可分为术前已存在的认知功能损害、术后谵妄(postoperative delirium, POD)、神经认知恢复延迟( delayed neurocognitive recovery, DNR)以及术后神经认知障  

Target disease:

Perioperative neurocognitive disorders (PND) refer to changes in cognitive abilities such as orientation, thinking, memory, attention, and self-awareness that occur in patients during the perioperative period. Based on the timing of onset, PND can be divided into four subcategories: preoperative cognitive impairment, postoperative delirium (POD), delayed neurocognitive recovery (DNR), and postoper

研究目的:

本研究旨在验证神经阻滞复合浅全身麻醉相较于椎管内麻醉是否具有降低老年患者下肢关节置换手术围术期神经认知障碍发生率的潜力。通过比较两种麻醉方式的效果,我们旨在为手术团队提供更可靠的临床指导,以最大程度地降低老年患者术后神经认知障碍的风险。本研究采用 MRI 成像技术,旨在探究老年下肢关节置换患者围术期隐匿性卒中的发生情况,并运用多种数据处理方法,对麻醉方式、术后神经认知障碍与隐匿性卒中之间的关联进行深入分析。通过综合考察这些因素,我们期望能够更全面地理解术后神经认知障碍的发病机制,为相关临床实践提供科学依据。  

Objectives of Study:

This study aims to investigate the potential of nerve block combined with superficial general anesthesia to reduce the incidence of perioperative neurocognitive disorders in elderly patients undergoing lower limb joint replacement, compared to spinal anesthesia. By comparing the effects of the two anesthesia techniques, we aim to provide the surgical team with more reliable clinical guidance to minimize the risk of postoperative neurocognitive disorders in elderly patients. This research employs MRI imaging technology to explore the occurrence of covert strokes in elderly patients undergoing lower limb joint replacement and utilizes various data processing methods to analyze the associations between anesthesia techniques, postoperative neurocognitive disorders, and covert strokes. Through a comprehensive examination of these factors, we hope to gain a deeper understanding of the pathogenesis of postoperative neurocognitive disorders, thereby providing scientific evidence for relevant clinical practices.

测量方法:

对于PND的测量,使用了神经心理学组套量表来测量。主要包括数字广度测试、数字符号测试、循迹连线实验A、词汇流畅性测试、斯特鲁色词测验、霍普金斯语言学习测试。根据术前术后量表得分的差值去除学习效应后使用Z分法计算得出患者是否发生PND。

One week postoperatively

Measure method:

For the assessment of PND, a neuropsychological battery was employed, which primarily included the Digit Span Test, Digit Symbol Test, Trail Making Test A, Verbal Fluency Test, Stroop Color-Word Test, and the Hopkins Verbal Learning Test. The difference between preoperative and postoperative scores was calculated to eliminate the learning effect, and the Z-score method was utilized to determine whether the patient experienced PND.
