摘要 目的:以异丙酚镇静降低老年人硬膜外麻醉术中心理应激水平,观察其对术后认知功能的影响。方法:选择年龄65~80岁前列腺电切病人160例,ASAⅠ~Ⅱ级,文化程度为小学水平,随机分为两组:对照组,单纯行硬膜外麻醉;试验组,硬膜外麻醉联合异丙酚镇静,每组80人。试验组行异丙酚靶控镇静,以脑电双频指数(BIS)监测镇静深度,使BIS值维持在80左右。手术前1 d及手术后第5天进行8项神经心理测试评估认知功能;术中每5 min记录一次无创平均血压;手术结束后30 min进行术中舒适满意度评价。结果:试验组术中平均血压明显低于对照组,术中舒适满意度优于对照组(P<0.05)。试验组手术前后数字广度顺向测验和听觉词语学习成绩无明显变化,术后第5天听觉词语学习成绩好于对照组(P<0.05)。两组病人术后认知功能障碍(POCD)的发生率差别无统计学意义(P>0.05)。结论:硬膜外麻醉术中辅以异丙酚镇静降低术中不良心理应激,病人舒适满意度较高,可能具有一定程度降低老年人术后记忆能力损害的作用,但对减少POCD发生率的作用有限。 AIM: To investigate the effects of epidural anesthesia combined with propofol sedation on postoperative cognition in the elder.METHODS: 160 patients,aged 65-80 years with primary school educational level,scheduled for transurethral resection of the prostate(TURP),were randomly assigned into two groups(n=80 each group): control group and test group.Patients in control group received only epidural anesthesia.Patients in test group received epidural anesthesia combined with propofol sedation.Propofol was admin...
