摘要
目的研究急性缺血性脑卒中患者阿替普酶静脉溶栓前后血凝状态的变化。方法选取静脉应用阿替普酶溶栓的急性缺血性脑卒中患者40例,测定溶栓前及溶栓后1、3、12 h的血栓弹力图。测定参数包括R值(凝血反应时间)、K值(凝血形成时间)、Angle角(凝固角)、MA值(两侧曲线最宽距离或称最大振幅)。结果溶栓前所有患者R值较正常值缩短,K值、Angle角和MA值正常;溶栓后1 h,R、K值较溶栓前增加;MA值、Angel角减小,差异有统计学意义(P<0.05),溶栓后3、12 h数值基本接近于溶栓前状态,差异无统计学意义(P>0.05)。结论血栓弹力图可以观察急性缺血性脑卒中患者阿替普酶静脉溶栓前后血凝状态的变化,对下一步临床治疗指导用药具有重要意义。
Objective To study the changes of blood coagulable states before and after Alteplase intravenous thromboly-sis in patients with acute ischemic stroke. Methods Forty cases of patients with acute ischemic stroke who used Al-teplase for intravenous thrombolysis were selected, the thrombelastogram before thrombolysis and 1, 3, 12 h after thrombolysis was detected. The detected parameters included R value （blood clotting response time）, K value （blood co-agulation formation time）, α angle （solidified angle）, MA value （the most wide distance between the two sides of the curve or called maximum amplitude）. Results Before thrombolysis, the R value of all patients were shortened compared with normal value, K value, α angle and MA value was normal; 1 h after thrombolysis, R, K values were increased compared with before thrombolysis; MA value and α angel was decreased, the differences were statistically significant （P〉0.05）. Conclusion The thrombelastogram can observe the blood coagulable states before and after Alteplase intravenous thrombolysis in patients with acute ischemic stroke, which is of great importance for further clinical guiding pharmacy.
