摘要: 目的:探讨血栓弹力图(TEG)联合D-二聚体/纤维蛋白(原)降解产物(FDP)比值对脓毒症并发弥散性血管内凝血(DIC)预后的预测价值。方法:选取2018年1月-2020年1月我院收治的107例脓毒症患者,其中41例患者发生DIC(DIC组),66例未发生DIC(非DIC组)。追踪DIC组临床结局,根据是否存活分为死亡组(14例)和存活组(27例)。所有患者确诊脓毒症后进行TEG和凝血指标检测。受试者工作特征曲线(ROC)分析TEG各参数和D-二聚体/FDP比值预测DIC患者预后的价值。结果:DIC组凝血反应时间(R)、血块生成时间(K)、LY30、FDP高于非DIC组(P<0.05),血细胞凝集块形成速(α角)、血凝块最大强度(MA值)、凝血综合指数(CI)、D-二聚体、D-二聚体/FDP比值低于非DIC组(P<0.05)。DIC组R、K、LY30、FDP随着APACHEⅡ评分增高而增高(P<0.05),α角、MA值、CI、D-二聚体、D-二聚体/FDP比值则降低(P<0.05)。死亡组R[(9.21±0.72) min vs.(6.53±1.42) min]、K[(5.32±2.42) min vs.(3.85±0.69) min]、LY30[(7.42±1.63)%vs.(5.29±1.52)%]、FDP[(10.64±1.67) mg/L vs.(8.54±2.34) mg/L]高于存活组(P<0.05),α角[(44.60±3.69)°vs.(52.12±3.65)°]、MA值[(24.02±0.69) mm vs.(36.35±3.02) mm]、CI(1.30±0.06 vs.1.69±0.21]、D-二聚体[(0.40±0.03) mg/L vs.(0.49±0.03) mg/L]、D-二聚体/FDP比值(0.10±0.02 vs.0.16±0.03)]低于存活组(P<0.05)。ROC分析结果显示MA值、α角、D-二聚体/FDP比值具有预测脓毒症并发DIC患者预后的价值,联合三项指标预测脓毒症并发DIC患者预后的AUC为0.960(95%CI:0.909~1.000),大于MA值、α角、D-二聚体/FDP比值(P<0.05)。结论:TEG联合D-二聚体/FDP比值有利于监测脓毒症并发DIC患者凝血状态,对病情评估和预后判断均有较高价值。

Abstract: Objective: To investigate the prognostic value of TEG combined with D-dimer/fibrin degradation product(FDP) ratio for sepsis complicated with disseminated intravascular coagulation(DIC).Methods: One hundred and seven patients with sepsis admitted to the ICU of our hospital from January 2018 to January 2020 were selected. Among them, 41 patients developed DIC(DIC group) and 66 patients did not develop DIC(sepsis group). Clinical outcome of DIC group was tracked and divided into death group(14 cases) and survival group(27 cases) according to survival. After diagnosis of sepsis, all patients were tested for TEG and coagulation indexes. The value of TEG parameters and D-dimer/FDP ratio in predicting the prognosis of DIC patients was analyzed by receiver operating characteristic curve(ROC).Results: R、K、LY30 and FDP in DIC group were higher than those in sepsis group(P<0.05), while αAngle and MA values, CI, D-dimer and D-dimer/FDP ratio were lower than those in sepsis group(P<0.05). DIC group R、K、LY30 and FDP increased as the APACHE Ⅱ score increases(P<0.05), αAngle and MA values, CI, D-dimer and D-dimer/FDP ratio decreased(P<0.05). R[(9.21±0.72) min vs.(6.53±1.42) min]、K[(5.32±2.42) min vs.(3.85±0.69) min]、LY30[(7.42±1.63)% vs.(5.29±1.52)%]and FDP[(10.64±1.67) mg/L vs.(8.54±2.34) mg/L]in death group were higher than those in survival group(P<0.05), while αAngle[(44.60±3.69) ° vs.(52.12±3.65) °]and MA values[(24.02±0.69) mm vs.(36.35±3.02) mm], CI[(1.30±0.06) vs.(1.69±0.21) ], D-dimer and D-dimer/FDP ratio[(0.10±0.02) vs.(0.16±0.03) ]were lower than those in survival group(P<0.05). ROC analysis results showed that the MA value, αAngle and d-dimer/FDP ratio were of value in predicting the prognosis of patients with sepsis complicated with DIC. The AUC value of the three indicators combined to predict the prognosis of patients with sepsis complicated with DIC was 0.960(95%CI: 0.909~1.000), which was greater than the MA value, αAngle and D-dimer/FDP ratio(P<0.05).Conclusion: TEG combined with D-dimer/FDP ratio is beneficial to the monitoring of coagulation status in patients with sepsis complicated with DIC, which is of high value for the assessment of the condition and prognosis.-
