以超声波及／或尿激酶对健康人静脉血形成的不同凝龄体外血栓行溶栓实验。结果显示，超声波具有优于尿激酶的溶栓效应（Ｐ＜０．０５）并可强化尿激酶的溶栓效应。超声波加用尿激酶较单纯超声波溶栓效果更佳（Ｐ＜０．０５）。超声波的溶栓效应与血栓凝龄有关，血栓愈陈旧，则超声波溶栓效应愈差（单纯超声波组ｒ＝－０．７４１，ｎ＝９６；超声波加尿激酶组ｒ＝－０．８０２，ｎ＝９６）。结论为，超声波具有肯定的溶栓效应和强化尿激酶溶栓效应，血栓形成时间愈短，超声波溶栓效果愈佳
Thrombosis of thrombus in vitro with different age-related coagulation in healthy human venous blood with ultrasound and / or urokinase. The results showed that ultrasound has better than urokinase thrombolytic effect (P <0.05) and can enhance the thrombolytic effect of urokinase. Ultrasound plus urokinase compared with simple ultrasound thrombolysis better (P <0.05). Ultrasound thrombolytic effect and thrombosis related, thrombosis more old, the worse the effect of thrombolysis ultrasound (ultrasound group r = -0.741, n = 96; ultrasound plus urokinase group r = -0.802, n = 96). The conclusion is that the ultrasound has a positive effect of thrombolysis and urokinase thrombolytic effect, the shorter the thrombosis time, the better the effect of ultrasound thrombolysis
