摘要 目的探讨降钙素原(PCT)在重型颅脑损伤院内感染患者早期诊断及预后评估中的价值。方法选择60例重型颅脑损伤患者,其中发生院内感染33例(感染组),未发生院内感染27例(未感染组),检测两组入院第1、3、5、7天血清PCT、C反应蛋白(CRP)及白细胞计数(wBc)水平,并进行比较。结果感染组入院第1、3、5、7天PCT水平明显高于未感染组[(2.22士3.75)μg/LJ比(0.28±0.22)μg/L,(3.49±3.04)μg/L比(0.24±0.01)μg/L,(2.82±2.01)μg/L比(0.20±0.27)μg/L,(2.39±2.19)μg/L比(0.19±0.06)μg/L],差异有统计学意义(P〈0.05);但感染组与未感染组在伤后各阶段(入院第1、3、5、7天)CRP、WBC水平比较差异无统计学意义(P〉0.05)。感染组PCT水平呈逐渐升高趋势,入院第3天达高峰,随着感染的控制,PCT水平呈下降趋势,5例重症感染患者中3例PCT持续增高(〉8.0μg/L),患者救治无效死亡。结论PCT对于早期诊断院内感染的特异度高于其他指标,血清PCT水平变化与感染严重程度密切相关,PCT在重型颅脑损伤院内感染的预后评估中发挥重要作用。
