Brainstem hemorrhage is a very dangerous brain hemorrhage with poor prognosis and high morbidity and mortality rate. Although the brainstem is small in size, it contains almost all important neurological functions, including consciousness, circulation, respiration, thermoregulation, internal environment stability, visual and auditory movement, and sensation. Because of its small size and many functions, once it is damaged by hemorrhage, it can cause serious neurological dysfunction and even endanger life. The prognosis of brainstem hemorrhage is related to the amount of hemorrhage, the site of hemorrhage and clinical symptoms. The amount of hemorrhage is an important factor affecting the prognosis of patients. According to statistics, the efficiency of conservative medical treatment is 100% for bleeding volume < 2 mL; for bleeding volume 2-5 mL, the morbidity and mortality rate is 16.7-33.3%; for bleeding volume 5.1-10 mL, the morbidity and mortality rate is >75%; and for very heavy patients with bleeding volume >10 mL, the morbidity and mortality rate is nearly 100%. According to statistics, the incidence of brainstem hemorrhage is lower in women than in men in all age groups, and there is a tendency for the disease to develop at a younger age. Clinical observation, in recent years, there is an increasing trend of male brainstem hemorrhage patients in their thirties, which is related to the stressful life and work of young men, uncontrolled diet, lack of exercise, etc. More seriously, the lack of awareness and attention to hypertension eventually leads to evil consequences. Young men, be alert to brainstem hemorrhage, make sure to control blood pressure, regular work and rest, moderate diet, and control weight.
