Brain hemorrhage has been vomiting for two more common reasons: 1. The patient has obvious intracranial hypertension. The hematoma of brain hemorrhage itself has an occupying effect, and over time there will be edema bands around the hematoma, leading to an increase in the occupying effect and compression of the surrounding normal brain tissue, which increases the total content of brain contents and leads to a sharp rise in intracranial pressure. The most common manifestation of high cranial pressure symptoms is headache, vomiting, sometimes accompanied by impaired consciousness. 2. This kind of vomiting is mainly the autonomic reaction caused by vertigo. It is difficult to relieve vomiting until the hemorrhage is completely absorbed, so in addition to using dehydrating agents to reduce edema, antiemetic drugs such as gastrodia are also used for treatment.
