摘要 目的探讨体外循环心脏手术中脑损伤的可能机制及其与炎症反应的关系。方法 24例在体外循环下(CPB)下行室间隔缺损(VSD)修补术的患儿,随机分为乌司他丁组(UTI组)和对照组。分别于手术前(T1)、复温至36℃(T2)、CPB后30min(T3)、CPB后4h(T4)抽取颈静脉血,用ELISA法测定S100β蛋白、神经元特异性烯醇化酶(NSE)及白细胞介素10(IL-10)浓度,用放免法测定肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6)、白细胞介素8(IL-8)浓度。结果 CPB前两组患儿血浆S100β蛋白和NSE浓度以及血浆细胞因子TNF-α、IL-6、IL-8及IL-10浓度差异均无统计学意义(P>0.05)。CPB后各时点,UTI组患儿血浆S100β蛋白,NSE,TNF-α、IL-6及IL-8浓度明显低于对照组,而UTI组患儿血浆IL-10浓度明显高于对照组,差异均有统计学意义(P<0.05)。结论 CPB下心内直视术对脑有一定的损伤,其作用机制可能是与CPB期促炎细胞因子的释放、上调抗炎细胞因子有关。
