[摘要] 目的 探索骨科手术中应用全身麻醉或椎管内麻醉对术后认知功能的影响。 方法 采用Meta分析的方法,系统检索PubMed、EMbase、Cochrane library、Ovid database、CNKI、万方数据库、维普数据库,检索时限均为建库至2014年10月31日,收集研究骨科手术中分别应用全身麻醉和椎管内麻醉对于术后认知功能障碍发生率影响的随机对照试验。使用Revman 5.3软件对数据进行统计学分析。 结果 骨科手术中蛛网膜下腔麻醉与全身麻醉相比,术后认知功能障碍的发生率差异无统计学意义(RR=1.83,95%CI 0.72~4.65,P=0.20);骨科手术中硬膜外麻醉术后认知障碍的发生率显著低于全身麻醉(RR=1.37,95%CI 1.00~1.88,P=0.05)。 结论 骨科手术麻醉中运用硬膜外麻醉相对于全身麻醉而言可以减少患者术后认知功能障碍的风险。

[Abstract] Objective To find out the influence of general and intraspinal anesthesia on post operative cognitive function. Methods By using Meta-analysis, literature was searched in PubMed, EMbase, Cochrane library, Ovid database, CNKI, Wanfang database and VIP database from inception to October 31 2014 to find randomized controlled trials about the incident of cognitive dysfunction after general or intranspinal anesthesia in orthopedic surgery. Analysis was performed by Revman 5.3. Results There was no significant different between the incident of post-operative cognitive dysfunction after general or spinal anesthesia in orthopedic surgery (RR=1.83, 95%CI 0.72-4.65, P=0.20). The risk of post operative cognitive dysfunction after epidural anesthesia was significant lower than that after general anesthesia (RR=1.37, 95%CI 1.00-1.88, P=0.05). Conclusion Using epidural anesthesia in orthopedic can lower the risk of post operative cognitive dysfunction than general anesthesia.

Bedford在1955年发现,很多老年患者在非心脏手术后都会有中枢神经不良并发症[1]。Price等[2]研究也表明,术后认知功能下降更容易发生在老年患者身上。随着世界人口老龄化加剧以及医疗技术的发展进步,接受手术的老年人数量越来越多,术后认知功能障碍的概念也逐渐被提出[3]。术后认知功能障碍的发生机制目前尚无定论,Bedford认为术后认知功能的障碍可能和麻醉方式有关[1]。老年人由于脊柱与关节的退行性变,接受骨科手术的概率增加。因此,骨科手术的麻醉方式选择是否会对术后认知产生影响引发了一定的争议。本研究采用Meta分析的方法,探索骨科手术中全身麻醉和椎管内麻醉对术后认知功能障碍发生的影响。……
