摘要 目的比较体外循环(CPB)、非CPB冠脉搭桥术(CABG)患者术后认知能力,并探讨其机制。方法择期单纯行CABG患者60例,心功能Ⅱ或Ⅲ级,随机分为非CPB组(Ⅰ组)和CPB组(Ⅱ组),每组30例,分别在非CPB和CPB下进行CABG。于麻醉诱导后即刻(T0)、术毕(T1)、术后6 h(T2)和术后24 h(T3)4个时点采集颈内静脉球部血,放免法测定血浆TNF-α、IL-1和IL-6。术前1 d和术后3、7 d,由心理医师分别进行一次简易智能状态检查(MMSE)评分,得分<24分为术后认知功能障碍(POCD)。结果术后7 dⅠ组4例(13%)、Ⅱ组10例(33%)发生POCD,两组POCD发生率相比,P<0.05。术后7 dⅠ组MMSE评分(27.0±1.9)分,Ⅱ组(25.7±2.4)分,两组MMSE评分相比,P<0.05。与Ⅰ组比较,Ⅱ组T1、T2、T3时点血浆TNF-α和T1、T3时点IL-1、IL-6浓度升高(P均<0.05)。结论非CPB下CABG患者术后认知能力较CPB下CABG患者强,其机制可能与非CPB下CABG患者血浆TNF-α、IL-1、IL-6水平较低有关。
