[摘 要] 目的:探讨体外心肺复苏(extracorporeal cardiopulmonary resuscitation,ECPR)支持前实验室检验指标对ECPR患者
30 d死亡风险的预测价值。方法:回顾性分析2018年1月—2023年12月南京医科大学第一附属医院急诊与危重症医学科行
ECPR转机>24 h的113例患者。根据患者30 d的存活情况分为死亡组(n=69)和生存组(n=44),采用单因素分析和Kaplan⁃Meier
分析两组患者ECPR上机前实验室检验指标,将差异有统计学意义及临床意义的指标进行多因素Cox比例风险回归分析,绘制
受试者工作特征(receiver operating characteristic,ROC)曲线,并计算 ROC 曲线下面积(area under curve,AUC)。结果:多因素
Cox分析显示,ECPR患者30 d死亡相关的风险因素包括乳酸[HR(95%CI):1.318(1.185~1.467),P < 0.05]、二氧化碳分压(partial
pressure of carbon dioxide,PaCO2)[HR(95%CI):1.008(1.001~1.013),P < 0.05]、钠[HR(95%CI):1.068(1.022~1.116),P < 0.05]、
肌酐[HR(95%CI):1.003(1.001~1.004),P < 0.05]、活化部分凝血活酶时间(activated partial thromboplastin time,APTT)
[HR(95%CI):1.001(1.001~1.002),P < 0.05]。而酸碱度(pH)[HR(95%CI):0.161(0.027~0.961),P < 0.05]、纤维蛋白原
(fibrinogen,FIB)[HR(95%CI):0.823(0.688~0.986),P < 0.05]可能具有潜在的保护作用。结论:ECPR患者30 d死亡相关的风
险因素主要包括乳酸、PaCO2、Na、肌酐、APTT,而pH、FIB可能具有潜在的保护作用。

[Abstract] Objective:To investigate the predictive efficacy of laboratory indexes for the 30⁃day risk of death in extracorporeal
cardiopulmonary resuscitation(ECPR)patients prior to receiving support. Methods:A retrospective analysis was performed on 113
patients who received ECPR transfer for more than 24 hours at the Emergency and Critical Care Medicine Department of the First
Affiliated Hospital of Nanjing Medical University between January 2018 and December 2023. The patients were categorized into two
groups based on their 30⁃day survival rate:the survival group(n=44)and the death group(n=69). The laboratory test indicators before
ECPR enrollment were examined using univariate analysis and Kaplan⁃Meier analysis for each of these groups. Cox’s proportional
hazards regression model was used in multivariate analysis to examine the laboratory test markers that showed statistically and
clinically significant differences. Receiver operating characteristic(ROC)curves were used to plot the subject characteristics,and the
area under the ROC curvewas calculated. Results:According to the multifactorial Cox analysis,lactate[HR(95%CI):1.318(1.185-
1.467),P < 0.05],PaCO2 [HR(95%CI):1.008(1.001-1.013),P < 0.05],Na[HR(95%CI):1.068(1.022-1.116),P < 0.05],
creatinine[HR(95%CI):1.003(1.001-1.004),P < 0.05]and activated partial thromboplastin time(APTT)[HR(95%CI):1.001
(1.001-1.002),P < 0.05]were among the risks associated with 30⁃day mortality in ECPR patients. Moreover,there may be preventive
benefits for pH[HR(95%CI):0.161(0.027-0.961),P < 0.05]and fibrinogen(FIB)[HR(95%CI):0.823(0.688-0.986),P < 0.05].
Conclusion:In patients receiving ECPR,the primary risk factors linked to 30⁃day death are lactate,PaCO2,Na,creatinine,and APTT,
