摘要 目的探讨老年人术后认知功能障碍(POCD)发生与Klotho蛋白的关系。方法选择65~75岁美国麻醉师协会(ASA)Ⅰ~Ⅱ级拟行胃癌根治术的老年患者30例,既往无手术史和中枢神经系统疾病史。麻醉诱导:咪达唑仑0.1~0.15 mg/kg、芬太尼0.002~0.004 mg/kg、依托咪酯0.15~0.3 mg/kg、维库溴铵0.1 mg/kg。麻醉维持:开始手术后根据麻醉需要追加适量芬太尼或舒芬太尼。然后静脉泵入瑞芬太尼维持镇痛、术中根据麻醉需要持续吸入七氟烷维持镇静,间断注射维库溴铵维持肌肉松弛要求即可。分别于手术前(T1)、手术结束(T2)两个时间点抽取静脉血,用酶联免疫吸附(ELISA)法测定Klotho蛋白含量。术前1 d、术后第1、3天对患者进行简易智力量表(MMSE)测验。结果术后第1天POCD发生率为33.33%。ELISA实验测量Klotho蛋白含量术后(83.91±14.17)比术前(120.07±25.19)明显降低(P<0.01),且发生POCD的患者Klotho蛋白含量术后均下降。结论 POCD的发生可能与Klotho蛋白含量的降低有关。
