Survival rates for brain stem hemorrhage are relatively meaningful for large populations around the world, around 60-70%. However, the level of treatment varies from region to region and from person to person, so the survival rate is not particularly meaningful if it is for a single individual. The survival rate is very low if there are high-risk conditions, such as brainstem hemorrhage is the main site of bleeding and the amount of bleeding is greater than 10 ml; the pupils have dilated bilaterally after the hemorrhage; it causes a decline in respiratory function, poor maintenance of oxygen saturation, and the need for tracheal intubation for respiration; and it produces a comatose state after the hemorrhage, which are high-risk factors of brainstem hemorrhage. If such conditions become more and more frequent, the survival rate will become lower and lower, and some even directly cause death. Therefore, it is important to have timely and relevant treatment for brainstem hemorrhage.
