[Correlation and Consistency of Two Different Methods for Detecting Coagulation Function].

OBJECTIVE: To study the correlation and consistency of the 2 different methods for detecting coagulation function.

METHODS: One hundred and six inpatients of ICU and department of gastroenterology in our hospital were retrospectively analyzed. The clinical data of thromboelastography and coagulation test were collected, and the detection results of 2 different methods were statistically analyzed.

RESULTS: The K, MA value and α-Angle in thrombelastometry significantly related with fibrinogen (r=-0.62, 0.36, 0.38, all P<0.01), and the R time significantly related with prothrombin time and activated partial thromboplastin time (r=0.31, 0.35, both P<0.01); the Kappa values of K value, MA value, α-Angle and fibrinogen value were 0.34, 0.46, 0.31 respectively (all P<0.05), and the chi square test values were respectively 1.12, 1.42, 0.14 (P=0.28, 0.21, 0.69); the Kappa values of R time in thrombelastometry with prothrombin time, activated partial thromboplastin time(APTT) were respectively 0.05,0.07 (P=0.88, 0.81), and the chi square tests showed that the Kappa values were respectively 19.57, 9.07 (both P<0.01).

CONCLUSION: Thromboelastography and coagulation test show significant correlation, with poor consistency, so the 2 kinds of methods can not be replaced for each other, which still can not be used to better assess the risk of bleeding.
