不同麻醉方式对骨科老年患者认知功能的影响

Influence of Different Anesthesia Techniques on Cognitive Function of Elderly Patients in Department of Orthopedics

目的研究不同麻醉方式对骨科患者术后短期认知功能的效应。方法 2014年1—12月期间,按照随机原则将研究患者分成全身麻醉组(静脉诱导)和硬膜外麻醉组(硬膜外诱导)。对比两种麻醉方式下的患者短期认知功能。结果麻醉消退患者苏醒后的6 h、12 h、24 h时硬膜外麻醉组患者的MMSE评分较全身麻醉组均显著升高、认知功能障碍发生率更低(χ2=7.89、7.32、8.41,P<0.05)。结论硬膜外麻醉安全性更高,具有推广价值。

Objective To study the influence of different anesthesia techniques on short-term cognitive function of elderly patients in the Department of Orthopedics after operation. Methods 264 elderly patients treated in our hospital during January 2014 and December 2014 were randomly divided into general anesthesia group（by Intravenous induction） and epidural anesthesia group（by epidural induction）. Short-term cognitive functions of patients of the two groups were compared. Results MMSE scores of the patients 6h, 12 h, 24 h after anesthesia dissipation were higher, and incidence of cognitive dysfunction lower, in the epidural anesthe-sia group than in the general anesthesia group, and the differences were statistically significant（χ2=7.89, 7.32,8.41,P〈0.05）.Conclusion Epidural anesthesia is worth promotion due to its higher safety.
