A clinical study of sepsis-related coagulation disorder / 中华急诊医学杂志

ABSTRACT

Objective To study in the correlation of the laboratory markers of coagulation,fibrinolysis and thrombosis in patients with sepsis and SOFA score,the procalcitonin (PCT) concentration and seven-day survival rate.Methods From February 2017 to March 2018,119 patients with sepsis admitted in ICU and another 119 patients with non-sepsis undergoing selective surgery were enrolled as control in this study.APTT (activated partial thromboplastin time),PT-INR (prothrombin time-international normalized ratio),FIB (fibrinogen),AT-Ⅲ (antithrombin Ⅲ),D-Dimer,FDP (fibrinogen degradation products),sTM (soluble thrombomodulin),TAT (thrombin antithrombin complex),PIC (plasmin-a2 plasminogen inhibitor complex) and t-PAI-C (tissue plasminogen activator and its inhibitor complex),were simultaneously monitored at admission.The correlation between the given laboratory markers mentioned and SOFA score,the PCT concentration and seven-day survival rate were analyzed with the Spearman correlation analysis.Results (① In the patients with sepsis,a positive correlation between SOFA score and sTM,t-PAI-C,TAT respectively was found,and a negative correlation between SOFA score and PLT (platelet count) was observed,and no correlation between SOFA score and PIC was noticed.(②) A positive correlation between PCT and sTM,t-PAI-C respectively was significant,a negative correlation between PCT and PLT was marked,and no correlation between PCT and AT-Ⅲ,TAT,PIC respectively was found.(③) A negative correlation between seven-day survival rate and sTM,t-PAI-C and TAT respectively was obvious,a positive correlation between seven-day survival rate and AT-Ⅲ,PLT respectively was occurred,and no correlation between seven-day survival rate and PIC was determined.Conclusions Soluble thrombomodulin (sTM),thrombin-antithrombin (TAT),antithrombin Ⅲ (AT-Ⅲ) and tissue plasminogen activator inhibitor complex (t-PAI-c) were good clinical monitoring indicators of coagulation disorder in patients with sepsis,which were the representative of the endothelial cell damage with highly activated coagulation,relatively insufficient anti-coagulation function and poor fibrin degradation ability.These were good adjuvants to PLT,INR and APTT for core diagnostic criteria of coagulation disorder in sepsis.
