Abstract:
【Objective】 To evaluate the effect of adding platelet GPⅡb/Ⅲa receptor inhibitor (A adjuvant) into the Batroxobin cup (A cup) on the accuracy of the thromboelastogram (TEG) platelet aggregation function test using the functional fibrinogen (function fiber cup) test results as a standard. 【Methods】 From December 2019 to May 2020, 100 (persons) whole blood samples were collected from patients who visited the Department of Neurology, Department of Cardiology, Department of General Affairs and Department of Rehabilitation of our hospital for TEG platelet aggregation function test, and the blood standard samples were divided into MA <25 mm group (n=50) and MA≥25 mm group (n=50) according to the A-cup blood clot intensity (MA) value (mm) measured by TEG, the two groups were subdivided into A cup group (n=50, respectively), A auxiliary group (adding A auxiliary in A cup) (n=50, respectively), and functional fiber cup group (n=50, respectively), each subgroup was tested once again. The linear correlation, platelet inhibition and the consistency of drug efficacy interpretation results in platelet Adenosine diphosphate (ADP) and Arachidonic acid (AA) pathway respectively between the three subgroups were compared. 【Results】 (1) In the MA<25mm group, the inhibition rates of ADP and AA pathway in platelet of A cup, A adjuvant and functional fibrin cup subgroups were (32.00±17.44) % vs (30.19±17.44) % vs (30.07±16.18) %, (24.3±33.53) % vs (22.53±30.9) % vs (22.37±31.2) %, respectively (R2 were all>0.975); (2) In the MA≥25 mm group, the inhibition rates of ADP and AA pathway in platelet of A cup, A adjuvant and functional fibrin cup subgroups were (34.34±33.59) % vs (18.45±24.42) % vs (18.01±24.33) %, (23.19±39.33) % vs (8.48±21.75) % vs (8.31±21.7) % ( R2 between the A cup group and the A adjuvant group were all<0.8, and R2 between the A adjuvant group and the functional fibrinogen cup group were all >0.975); (3)Take the test result of the functional fibrinogen cup as the standard, the correct rates of ADP and AA pathway drug efficacy interpretation were 82% (41/50) vs 100% (50/50) and 84% (42/50) vs 100% (50/50) respectively (P<0.05) between the A-cup group and the A adjuvant group, while the interpretation results of drug efficacy of the two pathway were consistent between the A adjuvant group and the functional fibrin cup group (P>0.05). 【Conclusion】 Adding A adjuvant to TEG platelet aggregation function test can effectively inhibit non-specifically activated platelets in the A cup in the detection of platelet aggregation function, truly reflect the function of fibrinogen and improve the accuracy of platelet inhibition rate.
