Comatose patients with cerebrovascular disease need nasal feeding, which is a manual method of placing a gastric tube into the patient’s nasal cavity and esophagus and advancing food and water through a syringe and nasogastric tube to provide the nutrition needed by the patient’s body, especially for patients with particularly severe cerebrovascular disease, which is often used. In the case of large cerebral infarction or cerebral hemorrhage that leads to coma, the patient is not able to eat normally or has difficulty swallowing or choking on water, etc., nasal feeding is required to ensure the nutrition and calories needed by the patient. The nasal feeding method can make food into a paste and inject it directly into the patient’s stomach, which can avoid frequent choking and coughing when ingesting food and choking the food into the trachea, which can easily lead to lung infection and, in serious cases, may cause asphyxia.
