摘要 目的 大手术后机体防御功能的改变在术后并发症和感染的发展中起着重要的作用,了解手术应激时Th1/ Th2平衡的变化,为进一步的免疫凋控提供依据 方法 15例行大手术的婴幼儿分别于术前、术后2 h、24 h和96 h果集外 周血标本,应用流式细胞仪测定IL-4和IFN-γ,酶标法(ELISA)测定IL-10和IL-6。结果 与手术前相比,经过PHA刺 激,细胞内的细胞因子IFN-γ在手术后明显下降,手术后第1天为(29.71±2.73)IU/ml,手术后第2天为(46.85±5.98)IU/ml, 与手术前(61.98±4.34)IU/ml相比,差异有显著性(P<0.05);Th2细胞因子IL-4水平在手术后亦下降;血清IL-10水平手术 后明显增加。结论 婴幼儿大手术后Th1细胞因子IFN-γ的产生明显下降。
