Coma of cerebral infarction is a more serious manifestation, but after active treatment, some of the patients will have improvement. Cerebral infarction coma is seen in large cerebral infarction, or atrial fibrillation and other causes of blockage of large blood vessels, embolism, in a short period of time the establishment of blood vessel collateral circulation is not good, it is easy to appear coma. During this period, the patient should be treated actively, for example, by intravenous thrombolysis with rt-PA or urokinase within 6 hours of the onset of the disease. If the thrombus is completely dissolved, the blood flow in the patient’s blood vessels will recirculate rapidly and the patient will be able to wake up completely without sequelae. If the patient’s blood vessels do not recanalize in time, the patient’s symptoms will be severe. Because with the progress of the disease, large cerebral infarction will also be prone to cerebral edema and brain hernia. If necessary, the patient should be given to do debridement decompression surgery, may have to give the patient dehydration, lowering the cranial pressure of the treatment. But cerebral infarction coma is more serious, during which the patient is also prone to complications of lung infection, urinary tract infection, so it is also necessary to prevent the emergence of the above problems.
