【摘 要】目的：研究分析使用不同麻醉与镇痛方法对老年患者下肢手术术后的早期认知功能影响。方法：选取在2015年6月—2017年8月我院接收的老年下肢手术患者78例，均分两组后对患者实施麻醉和镇痛方法，对照组使用静脉全身麻醉与静脉镇痛法，研究组患者则实施硬膜外麻醉与硬膜外镇痛法，对两组患者的认知功能情况进行对比。结果：研究组患者在麻醉后12h、24h和36h的疼痛评分低于对照组，比较有统计学意义(P<0.05)；研究组患者术后12h、第1d与第2d的神经功能评分优于对照组，比较有明显统计学差异性(P<0.05)。结论：在临床上，对老年下肢手术患者使用硬膜外麻醉与硬膜外镇痛方法的效果明显，可对患者的认知功能进行改善，值得予以使用。

    Effects of different anesthesia and analgesia methods on cognitive function in elderly patients after noncardiac surgery

    Abstract Objective： To study the effects of different anesthesia and analgesia methods on early cognitive function in elderly patients after non cardiac surgery. Methods：78 elderly patients with non cardiac surgery received in our hospital from June 2015 to August 2017 were divided into two groups. The anesthesia and analgesic methods were carried out to the patients. The control group was treated with intravenous general anesthesia and intravenous analgesia. The patients in the study group implemented the combination of lumbar epidural anesthesia and epidural analgesia ......
