Cerebral hemorrhage with dilated pupils and no spontaneous respiration and no reaction is mostly considered to be caused by increased intracranial pressure, cerebral hernia or brainstem compression.
1. Increased intracranial pressure: When cerebral hemorrhage occurs, it is easy to cause the patient’s local brain tissue to swell, resulting in intracranial occupying effect and causing increased intracranial pressure. Due to the increased pressure in the brain tissue, the patient’s nerves are easily involved, which may cause pupil dilation and unresponsiveness, and may also involve the patient’s respiratory system, resulting in the inability to breathe on their own.
2. Brain hernia: especially temporal lobe sulcus hernia, usually caused by increased intracranial pressure, resulting in the displacement of normal brain tissues and compression of the nerve centers in the patient’s brain. When the brain hernia is formed, it often involves the actinic nerve of the patient, which may cause the patient to show the pupil of the affected side to be dilated, and may be accompanied by involuntary respiration, unresponsiveness and other symptoms.
3. Brain stem compression: If the patient shows bilateral pupil dilation, it often suggests that the patient has brain stem compression, and at this time the patient is in the terminal stage, which can show symptoms such as pupil dilation, involuntary respiration, no reaction, etc., and the patient may at any time have respiratory and circulatory failure and cause death.
Cerebral hemorrhage pupil dilatation without spontaneous respiration and unresponsiveness may also be caused by other reasons, and should actively cooperate with the doctor to receive targeted treatment.
