摘要：

目的探讨急诊脓毒症患者血清降钙素原(PCT)水平的变化及影响脓毒症患者预后的危险因素。方法选取2012年1月至2016年5月该院急诊科诊断的206例脓毒症患者和184例非脓毒症患者,随访脓毒症患者28d的预后分为存活组(127例)和死亡组(79例),比较各组患者血清PCT、白细胞介素-6(IL-6)、WBC、急性生理学与慢性健康状况评分系统Ⅱ(APACHEⅡ)及序贯器官衰竭评分(SOFA)的变化。应用多元Logistic回归分析影响脓毒症患者预后的危险因素,并绘制ROC曲线分析各危险因素预测脓毒症死亡的价值。结果脓毒症组血清PCT、IL-6、APACHEⅡ评分、SOFA均明显高于非脓毒症组(P<0.01)。死亡组治疗治疗1、3、7d后的血清PCT水平均明显高于存活组(P<0.05)。年龄、血肌酐(Cr)、APACHEⅡ评分、SOFA、PCT及IL-6是影响脓毒症患者预后的独立危险因素。ROC曲线显示,年龄、Cr、APACHEⅡ评分、SOFA评分、PCT及IL-6预测脓毒症死亡的曲线下面积(AUC)及95%CI分别为:0.804(0.742～0.871)、0.673(0.608～0.746)、0.827(0.763～0.896)、0.764(0.718～0.814)、0.858(0.791～0.932)、0.715(0.643～0.797)。血清PCT、年龄及APACHEⅡ评分的最佳阈值分别为7.2μg/L、63.4岁、22.5分时,其预测脓毒症患者死亡的敏感度和特异度较好。结论影响脓毒症预后的危险因素较多,需采取相应措施及时控制感染,以降低患者的病死率。
