Ultra-early thrombolysis Stroke is the leading disabling disease in human beings, with 2.5 million new stroke cases in China each year, and 75% of the survivors are left with varying degrees of disability, 80% of which are cerebral infarction patients. Ultra-early thrombolytic therapy is the most effective means to reduce mortality and disability in cerebral infarction patients, with the aim of dissolving the thrombus, rapidly restoring blood perfusion to the ischemic area, and saving ischemic nerve cells. Thrombolysis should be performed within a therapeutic window of 6 hours from the onset of the disease in order to save the ischemic semidark zone. Neurointerventional techniques clarify the infarct lesion through imaging techniques, and super-selective cannulation injects thrombolytic drugs directly into the thrombus site to shorten the thrombolytic time and maximize the restoration of normal brain function. Early recognition of ischemic stroke commonly has four main warning signs: (1) weakness and numbness or paralysis of one or both sides of the body, upper and lower extremities or face. (2) Sudden blurring of vision in one or both eyes, or loss of vision, or double vision. (3) Difficulty in expressing speech or understanding. (4) Dizziness and loss of balance or any accidental fall or unsteady gait. “Time is brain”. If your family member or friend has a stroke, you must go to the hospital immediately, and you must go to a hospital with thrombolytic conditions. Thrombolytic treatment for acute cerebral infarction At present, cerebrovascular disease has become the main disease that endangers the health and life of middle-aged and elderly people in China. Cerebrovascular disease is a disease with high disability rate. According to statistics, about three-fourths of patients lose their working ability to varying degrees, which, together with various indirect losses, causes a heavy burden to the country and many families. Cerebral infarction is caused by ischemia, and because the tolerance of brain tissue to ischemia is particularly poor, once ischemia occurs, irreversible damage is rapidly produced in minutes to hours, therefore, the treatment of acute cerebral infarction must be carried out early, and the earlier the better. If thrombolytic therapy is carried out within 3-6 hours after the onset of the disease to restore blood perfusion in the infarct area, reduce neuronal damage and save the ischemic semidark zone, then the paralyzed limb may be completely restored to normal, and ultra-early thrombolytic therapy can sometimes prompt the patient to recover dramatically and receive immediate effect; on the contrary, if this time is missed, then the recovery of the paralyzed limb will be very difficult, or even left with lifelong paralysis.
