Brain stem hemorrhage is not easy to cure. Brain stem hemorrhage is often acute and dangerous, and it is one of the brain diseases with the highest mortality rate in clinical practice. Clinical causes of brain stem hemorrhage are atherosclerosis caused by high blood pressure and lesions in the surrounding tissues, which can cause brain stem hemorrhage. Clinically, the patient will have symptoms of coma and sighing breathing, which will lead to respiratory failure in the later stage and the symptom of pinpoint narrowing of the pupil. The patient may also experience gastrointestinal bleeding, which is caused by severe damage to the mucosa of the stomach and duodenum. Clinically, once a brainstem hemorrhage occurs, prompt treatment is needed, and strict control of blood pressure can effectively prevent rebleeding. At the same time, the patient needs to be put in hibernation, which effectively reduces metabolism and also reduces the oxygen consumption of brain cells.
