Thromboelastography Normal Reference Values in China Hunan Province

The Third Xiangya Hospital of Central South University498 enrolled

Overview

The purpose of this study was to establish the normal reference range of Thrombelastogram parameters in Hunan by a multicenter study, and to analyze the specificity of Thrombelastogram detection and the influence of gender, age and blood type on Thrombelastogram. The study will provide basic data and statistical basis for the establishment of normal reference range of Thrombelastogram in Hunan.

Thrombelastograghy (TEG) is an important test to assess the blood coagulation function to monitor the whole process of perioperative coagulation. TEG can evaluate the coagulation cascade, from platelet aggregation, clot strengthening and fibrin cross-linking to eventually clot lysis in small volume of whole blood. The reference range is one important element to influence the TEG results. At present, a number of studies have shown that reference range of TEG exists significant differences between different racial and geographic. At the same time, reagent manufacturers also suggested that each TEG laboratory should establish its own reference range. So it is important to establish our own reference range of TEG to guide the clinical blood transfusion and treatment.

Outcomes

Primary Outcomes

thromboelastography normal reference values

The subjects with normal routine coagulation test results would be included.Thromboelastography was performed by using TEG-5000 TEG-CK (Hemostasis System, USA), and the parameters were recorded. Parameters includes R (coagulation reaction time, initial fibrin formation time), K (Coagulation time), α (α-angle, thrombosis rate), MA (maximum amplitude, absolute agglutination strength of reactive blood clot), LY30 (fibrinolysis rate with 30 min after MA determination) and CI (integrated coagulation index).

Time frame: 2017.6.1-2017.12.1
