Patients with cerebral infarction who have headaches need to consider the following conditions: the first condition, massive cerebral infarction. Patients with large cerebral infarction often have obvious cerebral edema, occupying effect, resulting in significantly elevated intracerebral pressure, with headache, nausea, vomiting and other symptoms of high cranial pressure, in this case, you need to strengthen dehydration, using 20% mannitol, 125ml IV q8h, you can also use glycerol fructose 250ml IV q12h. The second condition, is that cerebral infarction has involved the cerebral cortex, so that the meninges are stimulated In this case, it is seen in lobar infarcts, such as frontal lobe infarcts, temporal lobe infarcts, occipital lobe infarcts, and can be treated symptomatically with analgesic drugs, commonly used ibuprofen, depot tablets, naproxen, etc. In the third case, if the patient has infarction, it may be accompanied by post-infarction secondary bleeding, and bleeding stimulation often causes headache. If the patient has no previous history of headache and suddenly develops this kind of headache, it is necessary to improve cranial CT examination in an emergency to clarify whether the patient has newly issued blood, and if so, it is necessary to stop the anti-platelet aggregation and blood-stasis activating drugs and change to neutral treatment, and edaravone is commonly used to remove Free radicals. Depending on the amount of bleeding, the patient should decide whether to add dehydrating agents to reduce intracerebral pressure.
