目的

评估急性出血性患者应用氨甲环酸(TXA)对凝血功能的影响。

方法

收集江门市人民医院急诊科收治的118例院前的创伤指数(TI)≥10分的急性创伤性出血患者,其中男性91例,女性27例;年龄14~73岁,平均(43.9±1.4)岁。随机分为TXA组和对照组,每组59例,其中TXA组男性45例,女性14例;年龄14~73岁,平均(44.3±15.2)岁。对照组男性46例,女性13例;年龄17~73岁,平均(43.6±14.6)岁。TXA组院前接受TXA治疗,对照组未接受TXA治疗。比较两组患者在现场和急诊科凝血指标和血栓弹力图差异。

结果

TXA组患者现场凝血指标与对照组比较差异无统计学意义(P>0.05)。在TXA组中血栓弹力图血栓形成的最大幅度(MA)从现场到急诊科变化不明显,而对照组MA降低了(1.2±2.7)mm,两组差异有统计学意义(P<0.001)。TXA组纤维蛋白原的溶解片段D2聚体的产生量较对照组显著降低(P<0.05)。

结论

急性创伤性出血患者院前早期应用TXA可抑制纤维蛋白原溶解活性稳定血凝块,减少D2聚体的产生,在创伤救治和创伤性凝血病防治中具有重要价值。

Objective

To evaluate the changes of coagulation in trauma hemorrhagic patients from on-scene to the emergency department after tranexamic acid (TXA) application.

Methods

A total of of 118 trauma patients with trauma index (TI)≥Ie were enrolled in this study, including 91 males and 27 females with an average age of 43.9 (14-73) years. The patients were randomly divided into TXA group (n=59) and control group (n=59): the TXA group received tranexamic acid before hospital, which included 45 males and 14 females with an average age of 44.3 (14-73) years; the control group was not treated with tranexamic acid, which included 46 males and 13 females with an average age of 44.6 (17-73) years. The difference of coagulation tests and thromboelastogram was compared between on-scene and emergency department.

Results

There was no difference in epidemiology between the groups. Coagulation assays on-scene had no significant difference between the TXA group and the control group. There was no significant change of maximum amplitude of thromboelastogram (MA) and fibrinogen levels in TXA group from on-scene to emergency, but MA in the control group decreased (1.2±2.7) mm; differences were significant between the two groups (P<0.001). D-dimers as a fragment of fibrinogen production, in TXA group decreased significantly compared with the control group (P<0.05).

Conclusion

In patients with acute traumatic hemorrhage, early prehospital application of TXA can inhibit fibrinogen solubility, stabilize blood clots and reduce the production of D-dimers, which shows the value of clinical trauma treatment and prevention of traumatic coagulopathy.
