摘要/Abstract

摘要： 目的探究血清降钙素原(PCT)联合阴离子隙(AG)检测在脓毒症患者预后中预测价值。方法选取2019年1月—2021年1月于我院治疗117例毒症患者作为研究对象,根据入院治疗28 d的预后情况,分为存活组(78例)和死亡组(39例),对比2组患者一般资料,采用多因素分析其高危因素,应用ROC曲线确定曲线下面积,评估血清PCT联合AG检测对该类患者预后的预测价值。结果 2组患者一般资料对比,年龄、中性粒细胞计数、血清C反应蛋白(CRP)、PCT、AG、APACHEⅡ评分差异有统计学意义(P<0.05);年龄、CRP、PCT、AG水平是该类死亡的危险因素;ROC曲线分析结果显示,血清PCT曲线下面积为0.737,最佳截断值为9.595;AG曲线下面积为0.791,最佳截断值为21.695;血清PCT联合AG检测曲线下面积为0.933,最佳截断值为1.3442。结论血清PCT联合AG检测对脓毒症患者预后具有较高的预测价值。

Abstract: Objective To investigate the predictive value of serum procalcitonin (PCT) combined with anion gap (AG) detection on the prognosis of patients with sepsis. Methods One hundred and seventeen patients with sepsis treated in our hospital from January 2019 to January 2021 were selected as study subjects and divided into survival group (78 patients) and death group (39 patients) according to their prognosis at 28 d of admission. The general data of the two groups was compared, multi-factor Logistic analysis of high-risk factors of sepsis patients was performed, area under the ROC curve was applied to assess the predictive value of serum PCT combined AG detection on the prognosis of sepsis patients. Results After comparing the general data of the two groups, the differences in age, neutrophil count, C-reactive protein (CRP), PCT, AG and APACHE II scores were statistically significant (P<0.05); multi-factor Logistic regression analysis showed that age, CRP, PCT and AG levels were risk factors for death in sepsis patients; the results of ROC curve analysis showed that the area under the curve of serum PCT was 0.737, with an optimal cut-off value of 9.595; the area under the AG curve was 0.791, with an optimal cut-off value of 21.695;the area under the curve of serum PCT combined with AG was 0.933, and the optimal cut-off value was 1.3442. Conclusions Serum PCT combined with AG assay had a high predictive value for the prognosis of patients with sepsis.
