硬膜外麻醉对老年骨科手术患者血流动力学及认知功能的影响

Impact of Epidural Anesthesia on Hemodynamics and Cognitive Function of Elderly Patients with Orthopedic Surgery

目的探讨硬膜外麻醉对老年骨科手术患者血流动力学、认知功能的影响。方法80例老年骨科手术患者随机分为两组各40例,对照组采用全身麻醉,实验组采用硬膜外麻醉,比较两组麻醉前后的血流动力学指标,以及手术前后的认知功能。结果麻醉后,两组的HR及MAP水平均显著低于麻醉前,但实验组的HR及MAP水平均显著高于对照组(P<0.05)。术后,两组的MMSE评分均显著低于术前,但实验组的MMSE评分显著高于对照组(P<0.05)。结论硬膜外麻醉应用于老年骨科手术患者可稳定术中血流动力学,且对患者术后认知功能的影响小。

Objective To explore the impact of epidural anesthesia on hemodynamics and cognitive function of elderly patients with orthopedic surgery.Methods 80 elderly patients with orthopedic surgery were randomly divided into two groups,with 40 cases in each group.The control group received general anesthesia,and the experimental group received epidural anesthesia.The hemodynamic indicators before and after anesthesia and the cognitive function before and after surgery were compared between the two groups.Results After anesthesia,the levels of HR and MAP of the two groups were significantly lower than those before anesthesia,while the levels of HR and MAP of the experimental group were significantly higher than those of the control group(P<0.05).After surgery,the MMSE scores of the two groups were significantly lower than those before surgery,while the MMSE score of the experimental group was significantly higher than that of the control group(P<0.05).Conclusions Epidural anesthesia applied in elderly patients with orthopedic surgery can stabilize intraoperative hemodynamics,and has less impact on patients'postoperative cognitive function.
