Once a cerebral infarction is diagnosed, if thrombolysis is indicated, it is best to give thrombolytic therapy, which will be very effective. If there is no indication for thrombolysis, conservative treatment is needed. First of all, anti-platelet and anticoagulation treatment is given, and the commonly used drugs are aspirin enteric tablets and low molecular heparin, and then dehydration and intracranial pressure reduction treatment are given. Because cerebral edema and intracranial hypertension will occur after cerebral infarction, commonly used drugs for dehydration to reduce intracranial pressure include 20% mannitol, compound mannitol, glycerol fructose injection, albumin, and tachyphylaxis, all of which can reduce intracranial pressure. Cerebral protective drugs such as cytarabine and gangliosides are also given, and blood-activating drugs such as Salvia injection and Chuanxiongzin injection are applied to resolve blood stasis. Stress ulcers may be caused after cerebral infarction, so proton pump inhibitors need to be given, while maintaining electrolyte balance for energy supplementation. These are the basic treatment measures after cerebral infarction.
