If the pupils are dilated to the edge due to serious diseases, such as brainstem hemorrhage, brain hernia, brain tumor, brain hemorrhage and craniocerebral trauma, the pupils are often dilated to the edge, indicating the disappearance of brainstem reflexes, which indicates an extremely critical condition; dilated pupils to the edge often indicate a very poor prognosis and the patient may die at any time, but if, after active resuscitation and removal of the cause, the bilateral pupils However, if the cause is removed after active resuscitation, bilateral pupil retraction indicates that the patient’s prognosis is likely to improve. A prolonged period of bilateral pupillary dilatation indicates the possibility of brain death, which often indicates that the condition is irreversible and that the patient may die at any time. Bilateral dilated pupils can also be seen in other diseases, so the ultimate prognosis depends on the cause of the disease and the patient’s response to treatment. If you are sure that the patient has no trauma, you can gently turn the patient’s head to the side and let the vomit flow out of the corner of the mouth to avoid accidental aspiration. Also note that the patient should not be moved at will to avoid aggravating the condition.
