Brain hernia is a neurosurgical emergency that needs to be dealt with, because once brain hernia occurs, if the increased intracranial pressure caused by brain hernia is not relieved in a timely manner, the patient will soon experience respiratory and circulatory failure and lead to death, so the main points of nursing care for patients with brain hernia mainly include: 1, the head of the bed is routinely elevated by 30 degrees in favor of reducing the jugular venous reflux in order to reduce the intracranial pressure; 2, this type of patient’s respiratory function is usually not very good, and requires urgent endotracheal intubation and respiratory ventilation, and nursing care needs to be aware of the respiratory frequency, oxygen saturation, etc. 3, the nursing care also needs to monitor closely the changes in body temperature, pulse rate, and blood pressure, etc.
