The risk period for brainstem hemorrhage is usually about 7 days. The brainstem is a very important center of the body, including breathing, heartbeat, blood pressure, pulse, body temperature and other vital centers are located in the brainstem. When the amount of bleeding in the brainstem is greater than 5ml, the patient is at risk. If the patient’s bleeding is more than 10 ml, the consequences are bad and may lead to the patient’s death. After brainstem bleeding, patients can develop serious complications such as intrapulmonary infections and stress ulcers of the digestive tract, all of which need to be treated aggressively. Moreover, the brainstem is a functional area and the chances of surgery are low, so there is no way to treat it through surgery, but only conservative treatment. A portion of people with bleeding greater than 5 ml may die from the failure of brainstem function.
