目的：探究不同方法的全身麻醉对老年患者术后认知障碍（POCD）的影响。方法资料随机选取2013年5月～2014年5月本院收治的95例老年患者，随机分为研究组48例，对照组47例。对照组行七氟醚吸入麻醉，研究组行瑞芬太尼+丙泊酚全凭静脉麻醉，分析两组麻醉效果。结果研究组MMSE评分术后3h恢复至麻醉前水平，对照组则为术后6h；研究组手术相关时间均少于对照组（P＜0.05）。结论静脉麻醉和吸入麻醉均可导致老年患者POCD，但前者与后者相比患者恢复更快。%Objective To explore different methods of general anesthesia on postoperative cognitive dysfunction(POCD) in elderly patients. Method 95 cases of elderly patients were randomly selected from May 2013 to May 2014 in our hospital, 48 of whom were divided into the study group, and the other 47 into the control group. The control group underwent sevolfurane anesthesia, while the study group underwent propofol+remifentanil total intravenous anesthesia, then the anesthetic effect of the two groups were analyzed. Results In the study group, the average time for the MMSE scores to go back to the level before anesthesia was 3 hours,while in the control group it was 6 hours. Almost all the surgery time in the study group was shorter than that of the control group ( P<0.05 ). Conclusion Both intravenous anesthesia and inhalation anesthesia could lead elderly patients to POCD, but compared with the later, the former patients would recover faster.
