摘要
背景:术后认知功能障碍与老年人术后并发症的发生及死亡率密切相关。设定相同麻醉条件下硬膜外镇痛比静脉镇痛对老年患者下肢关节置换及内固定后早期认知功能的影响较小。目的:比较两种不同的镇痛方法对老年患者下肢骨科手术后早期认知功能的影响。方法:60例拟行择期下肢手术的老年患者,随机接受椎管内麻醉继以术后静脉镇痛或以硬膜外镇痛。结果与结论:术后认知功能障碍发生率静脉镇痛组为47%(14/30),硬膜外镇痛组为30%(9/30例),两组间差异非常显著(P<0.01)。Logistic回归分析显示受教育年限短和髋关节置换术是发生术后早期认知功能障碍的独立危险因素。结果表明,老年患者在下肢关节置换及内固定后早期有38%的患者发生了认知功能障碍,且硬膜外镇痛较静脉镇痛发生术后认知功能障碍明显降低。受教育年限短和髋关节置换本身是术后早期认知功能障碍的危险因素。
