| 摘 要： | 目的 观察老年全麻患者围术期血清兴奋性氨基酸(EAA)浓度的动态变化.方法 择期行非心脏手术气管内全麻患者41例.根据年龄不同分为老年组31例,年龄≥65岁;青年组10例,年龄25～45岁.所有患者术后均使用静脉镇痛.采用简易智力状态检查法(MMSE)分别评估患者麻醉前及术后24、48、72 h内的认知功能.于麻醉前(T1)、术毕(T2)、术后24 h(T3)、48 h(T4)、72 h(T5)经颈内静脉采血2 ml.采用反相高效液相色谱荧光法(RP-HPLC)检测血清氨基酸浓度.结果 MMSE评分老年组术后24、48 h明显低于麻醉前和青年组(P<0.05).与T1时比较,T3、T1时老年组血清谷氨酸(Glu)、天冬氨酸(Asp),甘氨酸(Gly)浓度升高(P<0.05或P<0.01),T5时恢复.T1时老年组血清Glu、Asp、Gly浓度低于青年组,但差异无统计学意义;T3时老年组Glu、Asp、Gly明显高于青年组(P<0.05).结论 老年患者术后早期存在EAA水平升高,Glu可能参与术后认知功能障碍(POCD)的病理生理过程.老年患者全麻术后早期血清EAA水平较高可能是老年POCD发病率高的原因之一.

| Abstract: | Objective To observe the perioperative change of plasma excitatory amino acids(EAA)in senile patients undergoing general anesthesia during operation and explore its clinical significance.Methods Forty one patients underwent selective surgery under general anesthesia.The patients were divided into two groups according to the age of patients,the old group(31 patients,aged over 65 years)and the young group(10 patients,aged 25 to 45 years).Venous PCI was operated in all the patients.Cognitive function was evalu... |
