Abstract:
Objective To observe critical patients with thrombocytopenia,and exam their coagulation function,so as to diagnose disseminated intravascular coagulation(DIC)in the early stage.Methods Totally 56 critical patients complicated with thrombocytopenia were enrolled in the investigation;complete set of DIC tests were performed.A total of 26 cases were diagnosed as DIC according to the criteria from the International Society of Thrombosis Haemostasis(ISTH).The sensitivity,specificity,accuracy,likelihood ratio,predictive value of prothrombin time(PT),activated partial thromboplastin time(APTT),thrombin time(TT),fibrinogen(Fg),antithrombin Ⅲ and bleeding signs(including petechia and ecchymosia)were calculated by applying fourfold table.Results The specificity of PT prolongation and Fg reduction was 87.0%;the sensitivity of ATⅢ decrease,and each of PT prolongation,Fg reduction,and bleeding(including petechia and ecchymosis)were as high as 96.0%.Conclusion Multi-markers based on thrombocytopenia are likely to improve sensitivity and specificity of DIC diagnosis.
