It is possible to cure a relatively small amount of brainstem hemorrhage, but if the amount of brainstem hemorrhage is relatively large, the mortality rate is very high. Brainstem hemorrhage is often caused by the rupture of blood vessels in the brainstem due to hypertension or aneurysmal malformation, or the formation of brain hemorrhage flowing down various interstitial spaces into the brainstem. The compression of the brainstem by the hematoma may produce various manifestations of cranial nerve damage. After a brainstem hemorrhage, the patient may experience a sudden loss of consciousness and develop eye movement disorders, peripheral facial palsy, and tongue palsy. The presence of brainstem hemorrhage can be diagnosed by performing a CT scan. Since brainstem hemorrhage is a disease with a high mortality rate and is a neurological emergency, it should be treated promptly with emergency neurology once it is detected, otherwise high fever, stress ulcers, seizures, and severe waves to the respiratory and circulatory centers leading to brain herniation formation or death will soon occur. Treatment principles are based on maintaining the patient’s water-electrolyte balance, adjusting the patient’s blood sugar changes, lowering intracranial pressure, and anti-infection. If the patient is irritable and has a significant headache, appropriate sedatives and analgesics can be used for symptomatic treatment, and the patient needs to keep the bowels open, and surgery can be considered if appropriate.
