Heavy craniocerebral injury may have symptoms such as impaired consciousness, elevated blood pressure, slowed heart rate, irregular respiration and even pupil dilatation occurring in brain herniation.
The reason why patients with severe craniocerebral injury have impaired consciousness may be due to the stimulation or destruction of the upward reticular formation in the brain that maintains normal arousal, and the patients may be lethargic or comatose, which may be manifested as unresponsive to calling, tingling and visible contraction of limbs, and so on; if they are in a deep coma, they may even be unresponsive to any stimulation, which is usually indicative of a poor prognosis.
Increased blood pressure, slowed heart rate and irregular breathing are all symptoms of Cushing’s reaction, which is mostly seen in patients with acute intracranial pressure increase, while patients with severe craniocerebral injury may have acute intracranial pressure increase due to rapid formation of large hematoma in the cranium; at this time, the hematoma may compress the movable eye nerve resulting in pupil dilatation, and persistent high cranial pressure that is not relieved may result in brain herniation, which may endanger the life of the patient.
This disease is highly specialized, should go to the regular hospital in time for salvage treatment, under the guidance of the doctor to determine the specific treatment plan, and actively cooperate with the treatment.
