Patients with cerebral infarction usually need about 2 weeks of infusion therapy, mainly applying shuxin, vincristine, sparing blood, chuanxiongzine and safflower to improve blood circulation, edaravone, cytarabine, cerebroprotein hydrolysate, piracetam, oracetam and vincristine to improve cerebral metabolism and neuroprotective therapy. Application of butylphthalide to improve the signs and symptoms of neurological deficits. Application of fibrin-lowering enzymes and ankyrase for fibrin-lowering treatment. Application of hydroxyethyl starch for volume expansion therapy. Infusion therapy is mainly applied to patients in the acute phase. The acute phase is defined as the onset of disease within 2 weeks, and if the patient is within 6 hours it is generally called the hyperacute phase. Thrombolytic therapy can be given in the hyperacute phase, and the main drugs commonly used are alteplase and urokinase. If the patient is more than 2 weeks, within 1 year, it is generally called the recovery period, and patients in the recovery period are mainly treated with rehabilitation. If the patient enters the post-acute phase, the treatment is generally less effective.
