When brain hemorrhage occurs in coma, changes in consciousness, pupil size, blood pressure, and respiration need to be strictly noted, and comatose patients should be monitored when available . Patients with increased intracranial pressure can be given cranial pressure-lowering treatment, and the drugs commonly used clinically are mannitol, glycerol fructose and tachypnea. The patient is in passive flat position, which may easily cause aspiration pneumonia, and should be turned and patted on the back regularly. It may easily cause deep vein thrombosis in the lower limbs, and should be given limb rehabilitation treatment, and pneumatic therapy can also be given. Patients may have hemiplegia at the same time, or sensory disorders such as hemianopia or hemiplegia. If brainstem hemorrhage occurs, dysphagia and choking on drinking water may occur. If the patient has difficulty recovering in the short term, he or she should be given a lower gastric tube, retained gastric tube, nasal feeding diet and nasal drug administration. If the patient is suitable for surgery in the early stage, surgical treatment can be considered.
