Hypertensive cerebral hemorrhage is very dangerous and may endanger the patient’s life, brain herniation, etc., as follows: a. Life-threatening: the patient develops respiratory and circulatory failure, and then dies. Hypertension causes the greatest danger of brainstem hemorrhage, because there are many nerve, respiratory and fluid centers in the brainstem, once this part is compressed by bleeding, the patient may instantly experience apnea and cardiac arrest, and then die. Second, brain herniation: If the brain parenchyma bleeds and the bleeding volume is very large, the patient will develop brain herniation, and the risk of death in patients with brain herniation is also very high. Third, other: most patients with cerebral hemorrhage are left with sequelae, which may include paralysis, hemiplegia, or diaphoresis, speech impairment, vision loss or lead to blindness.
