The severity of an epidural hematoma depends mainly on the epidural hematoma, the amount of which is not severe and severe in two cases, as follows: I. Not severe: Because the most critical relief in the treatment of all neurosurgical disorders is to ensure that the pressure inside the head is normal. If there is only a small amount of epidural hematoma, the intracranial pressure may have been in the normal range, or mildly increased intracranial pressure. For this patient the relative symptoms and condition will be milder and only a close review of the head CT is needed to assess the patient’s consciousness score. Severe: If the amount of epidural hematoma is relatively large, such patients will immediately have dilated pupils on one side and may even develop coma. In such patients, most prognosis is good if early surgical treatment is performed to relieve the symptoms of increased intracranial pressure caused by the hematoma. It must be treated surgically as early as possible, and if delayed for a longer period of time, the longer the damage to the nerve, the more the nerve cells enter an irreversible stage. The severity of the epidural hematoma depends mainly on the amount of intracranial hemorrhage. For epidural hematoma in patients with impaired consciousness, early surgical intervention must be performed.
