摘要 目的 :探讨降钙素原对预测危重患者院内获得性菌血症的价值。方法 :回顾性分析2010年5月—2013年10月上海长征医院急救科患者的临床资料,行降钙素原、内毒素、C反应蛋白、白细胞计数及血培养等,根据院内获得性菌血症诊断标准对不同血培养结果之间的各炎症指标进行比较,并绘制其预测菌血症的ROC曲线。结果:血培养阳性组中降钙素原、内毒素及C反应蛋白高于血培养阴性组(P〈0.05),其中革兰氏阴性菌组升高更明显,白细胞计数在各组间无显著差异;降钙素原ROC曲线下面积(95%CI=0.81,0.78~0.85,P〈0.001),有助于预测菌血症。结论:降钙素原对于预测危重患者院内获得性菌血症有一定价值。
