Vomiting in cerebral infarction is generally built under the following conditions: First, it may be due to the increase of intracranial pressure caused by large cerebral infarction, and patients may have headache, nausea and vomiting, which should be mainly treated with cranial pressure lowering, and the commonly used cranial pressure lowering drugs include mannitol, mannofructose and tachyphylaxis. Secondly, it may be due to cerebral infarction combined with stress ulcers, causing upper gastrointestinal bleeding, and patients may experience nausea, vomiting, or vomiting blood, etc. Clinically, ice saline intragastric lavage should be given, and thrombin treatment can also be given. Thirdly, it may be due to electrolyte disorders caused by the treatment process of cerebral infarction, such as hyponatremia, and patients with severe hyponatremia may also have nausea, vomiting and so on, and hyponatremia should mainly be corrected, and hypertonic salt is generally applied intravenously clinically.
