Patients with right-sided hemiparesis in cerebral infarction can be treated with intravenous thrombolytic therapy, including rt-PA and urokinase, if the patient is within 6 hours of onset. If the patient’s onset time has exceeded the time window for thrombolysis, the patient can be given antiplatelet aggregation therapy with oral bacitracin or poliovir. For fibrin-lowering treatment, patients can be given sedative bactrim and treatment to improve cerebral blood circulation by giving them sedative hemosiderin injection or danshen chuanxiongzin injection. In addition, it is important to exercise the limbs to avoid limb paralysis and limb contracture.
