目的:体外循环手术后测定血浆血小板激活因子( PAF)、白细胞介素-8(ⅠL-8)、γ-干扰素(ⅠFN-γ)水平变化,分析血浆PAF、ⅠL-8、ⅠFN-γ水平与急性肺损伤/急性呼吸窘迫综合征关系。方法选择2006年12月份至2014年6月份应用体外循环手术治疗的156例患者作为观察对象,其中67例并发急性肺损伤/急性呼吸窘迫综合征,即观察组,另89例未发生急性肺损伤/急性呼吸窘迫综合征作为对照组。在术前、术后1d、3d及7d采用酶联免疫吸附测定法检测血浆中PAF、ⅠL-8及ⅠFN-γ浓度,并对结果进行统计学分析。结果观察组患者手术后血浆PAF、ⅠL-8和ⅠFN-γ浓度明显高于手术前( P 0.05);观察组血浆PAF、ⅠL-8和ⅠFN-γ浓度明显升高并在术后3 d时达最高值后逐渐下降,但术后各时间的浓度值均显著高于手术前( P
