Bleeding in the brain is very common in the clinic, and there is a relatively good treatment process for this condition, but it must be judged according to the actual situation. First of all, the head CT should be reviewed to clarify the amount of bleeding in the brain, the location and the various relationships adjacent to the surrounding area, to clarify the relevant specifics, and sometimes it is also necessary to carry out angiographic testing to clarify the specific factors, and when it is clarified, it is necessary to observe the bleeding in the brain to see exactly what the state of the bleeding is. If the bleeding volume is large and the condition is critical, craniotomy or interventional therapy is required. However, if the bleeding is relatively light, it is more likely to be treated with internal medicine, such as hemostasis, rehydration, dehydration, lowering the cranial pressure, as well as improving the cerebral circulation, cerebral protection, and a series of other measures, of which the most commonly used to lower the cranial pressure is mannitol. However, if there is some damage to renal function, glycerol fructose with furosemide can be applied for treatment. When the condition is stabilized, those with functional impairment also need to carry out rehabilitation and functional exercise in the later stage, which is more beneficial to the patients.
