摘要 目的观察血清降钙素原(PCT)、血浆氨基酸B型钠尿肽前体(NT-pro-BNP)水平在脓毒血症病程中的变化及其临床意义。方法选择住外科重症监护病房(SICU)的80例成年脓毒血症患者为研究对象,分别在发生脓毒血症的第1、3天及出SICU当天检测其血清PCT、血浆NT-pro-BNP水平,记录当天的急性生理和慢性健康状况-Ⅱ(APACHE-Ⅱ)评分,患者发生脓毒血症后前3 d及入住SICU期间总的出入水量,随访患者入SICU后的生存状况,并据此将患者分为存活组和死亡组。结果 80例患者中,65例存活,15例死亡。两组患者第1天APACHE-Ⅱ评分、血浆NT-pro-BNP和血清PCT水平相近(均P>0.05);第3天死亡组血浆NT-pro-BNP水平、APACHE-Ⅱ评分、出入水量均明显高于存活组(均P<0.05),血清PCT水平两组差异无统计学意义(P>0.05);出SICU当天,死亡组的血清PCT、血浆NT-pro-BNP水平和APACHE-Ⅱ评分、住院期间总出入量均明显高于存活组(均P<0.05)。血清PCT、血浆NT-pro-BNP水平分别与APACHE-Ⅱ评分相关(r=0.583,P<0.05;r=0.475,P<0.05);血清PCT与血浆NT-pro-BNP水平相关(r=0.769,P<0.05),血浆NT-pro-BNP与患者总出入水量情况相关(r=0.494,P<0.05)。结论脓毒血症患者血浆NT-pro-BNP水平与感染指标血清PCT水平相关,血清PCT、血浆NT-pro-BNP水平持续进行性升高提示预后不良。
