脑梗死具有高发病率、高致残率、高病死率,至今还未找到一种确切有效的治疗方法。在血液稀释、血管扩张及溶栓等治疗方法中,溶栓疗法被认为是急性脑梗死最有效、最有前途的治疗方法。按照“治疗时间窗”的概念,首次溶栓应在脑血栓形成3～6小时内即超早期时进行。但由于基层医院条件有限,往往超过6小时,因此我们放宽到发病7～72小时。 Cerebral infarction with high incidence, high morbidity, high mortality, so far still not find an exact and effective treatment. Thrombolytic therapy is considered as the most effective and promising treatment for acute cerebral infarction in the treatment of hemodilution, vasodilation and thrombolysis. According to the “treatment time window” concept, the first thrombolytic should be thrombosis in 3 to 6 hours in the ultra-early stage. However, due to the limited conditions of grass-roots hospitals, often more than 6 hours, so we relaxed to onset of 7 to 72 hours.
