Once brainstem hemorrhage occurs and fever appears, it is mostly considered to be central fever. This is due to the gradual decline or loss of the function of the brainstem to set and regulate body temperature after hemorrhage, leading to abnormally high body temperatures, typically rising above 40°C, manifesting as severe central nervous system fever. This usually indicates that the patient's condition is critical and life-threatening at any time. If the fever is not central but due to pulmonary infections or other causes, it can be treated with antibiotics and antipyretics, which can achieve good therapeutic effects. Whether the patient survives depends on the location of the brainstem hemorrhage and the amount of bleeding.
