It makes more sense to operate on a patient with a herniated brain because once a brain hernia occurs, it means that the patient is currently in a critical condition and in a near-death state. If the patient is not treated aggressively, the patient may die at any time due to brainstem failure. Patients with brain herniation generally need to clarify the cause of the disease, reduce intracranial pressure and other treatments, as follows: 1, clarify the cause of the disease: the main cause of brain herniation should be clarified, and it is generally recommended to give the patient an emergency room, and perform a cranial CT examination. Cranial CT helps to clarify whether intracranial hemorrhage, obstructive hydrocephalus, or other causes of brain herniation, only to clarify the cause to do targeted treatment.2, reduce intracranial pressure: reduce intracranial pressure can be considered, choose intravenous drip mannitol, dehydration to reduce intracranial pressure, for the next step in the treatment of time, and finally you can choose to be treated through the craniotomy method of treatment. Only in this way can the patient’s life be effectively saved.
